Drawing our inner selves

I'm trying to review what I've been doing over the last few years and as I do I realise I repeat myself over and over again, so forgive me, but as I get older I forget what I have said, or I need to say it again, slightly differently to ensure what I said still makes sense, even though I now have more but perhaps contradictory information. 

Lines in the visual field (circular left) map to lines in the striate cortex: From Bressloff et al

When trying to visualise interoception, I often go back to entoptic forms, those shapes that we generate from inside ourselves, because both sets of phenomena are encountered as 'inner' experiences. Heinrich Klüver extrapolated four groups of entoptic visual phenomena that he called 'Form Constants'; these were, lattices, cobwebs, tunnels, and spirals. It has been theorised that structures of neural interconnectivity could dictate the type of emergent phenomena that are produced. Neural network models of geometric hallucinations have incorporated empirical insights from neural anatomy and physiology, including the spatial arrangements associated with different neuronal cell types. It has therefore been argued that the worldwide prevalence of certain types of geometric visual patterns found in prehistoric art can be best explained by humanity’s shared neurobiological embodiment. The mathematical biologists Jack Cowan and G. Bard Ermentrout who created the first mathematical model of visual hallucinations in the 1970s, were the key researchers behind the realisation of why these specific shapes happen. Our primary visual cortex maps what we see using a grid-like coordinate system and when our brain is hyper-excited, whether by psychedelics as in Klüver's case or sensory deprivation, such as being immersed in a dark cave for a long time, migraines, or near-death experiences, it triggers spontaneous electrical waves of activity. Because of the way our brain's visual field is physically mapped (a mathematical transformation called log-polar mapping), straight lines of electrical activity in the brain are perceived by your mind as being bent, producing perceived images of spirals, tunnels, and lattices. The human visual system naturally performs a log-polar transformation in the process of sending signals from the spherical retina to the flat primary visual cortex. Because entoptic images are cast directly onto the retina, they are subjected to this exact same mathematical warping before your brain ever "sees" them, In short, when you see a form constant, you are quite literally looking at the physical wiring of your own brain.

Klüver's form constants

But I am also an image maker and my area of research covers the complex relationships between how we read symbolic material culture, how we encounter and attempt to visualise first-person experience and how insights into neurobiology can be used to give meaning to the ongoing awareness of our inner selves. In particular I'm interested in neurobiology as a growing area of research focused on the interrelated concepts of sense-making, value and sensorimotor activity and how the mapping of our complex interconnected bodies can effect our visual ideas of embodied thoughts. 




Images from an interoception workshop

Workshops exploring how other people might visualise interoception have revealed the fact that images related to entoptic forms will emerge over and over again, these workshops are held at regular intervals and during the time I have been holding them, I have also made images of my own interoceptual experiences and other people's; as in the two prints below. In these images I attempt to synthesise an awareness of the expressive power of figurative distortion, alongside the embodiment of shapes and forms that are of an entoptic nature; spirals, zig-zags and dots, engaging the visual field alongside more figurative symbols.

The fact that Karl Deisseroth, Peter Hegemann, and Georg Nagel won the 2026 Nobel Prize in Physiology or Medicine for their discoveries concerning light-gated ion channels and optogenetics, has furthered my intrigue as to how our cells communicate to shape brain functions such as memories, feelings, and behaviours. Their discovery is built on an awareness of how green algae of the genus chlamydomonas can swim towards light by sensing it through a primitive eyespot. Experiments revealed that the eyespot contained a light-sensitive protein that helped convert photons into an electrical signal, causing chlamydomonas to move. This signalling system works like a switch, light sensitive proteins being at the switch's heart and since its discovery, optogenetics has helped researchers pinpoint exactly which neurons control different brain functions including pain, thirst, food intake, reward, attention, some social behaviours and caring for the young. Neurons in mammals normally use voltage-gated, ligand-gated, or mechanically-gated ion channels to communicate and fire electrical signals. They are not naturally photosensitive (with the exception of specialised photoreceptor cells in the retina like rods and cones, which use a G-protein-coupled signalling cascade, rhodopsins coupled to second messengers, rather than direct light-gated ion channels). However, neurons can be made to have light-gated ion channels through the application of optogenetics, whereby scientists introduce genes from microorganisms (such as the green alga Chlamydomonas reinhardtii) into neurons using viral vectors (a genetically modified, harmless virus used as a delivery vehicle to transport therapeutic genetic material (DNA or RNA) into target cells) or other forms of genetic modification. By now being able to switch neurons on and off, as well as being able to identify neurons controlling brain functions, scientists also discovered the neurons that regulate functions beyond the brain, like the circadian rhythm and certain immune responses.

I'm particularly interested in the developments surrounding the application of optogenetic technologies because I have ventricular arrhythmia, an abnormal heart rhythm. This disruption in my heart rhythm can reduce blood flow and lead to serious or life-threatening complications, including sudden cardiac death. Individual heart cells (cardiomyocytes) possess molecular clocks, driven by core clock genes, that regulate ion channels and energy metabolism. These cellular rhythms control how the heart's pacemaker and electrical waves function at different times of day. Therefore my condition may well be due to a fault in a clock gene that regulates an ion channel. Optogenetic advances have now led to medical applications that may at some point in the future come to have an impact on how my condition is treated.

So on the one hand I try to keep up with recent scientific advances, but on the other hand some things in relation to the evolutionary history of human beings, are very old indeed.  My reading implies that basic formal elements or 'form constants' can be used to carry information in a format that would have been familiar to humans experiencing drawings over 40,000 years ago and ideas which may have been communicable at the time may become so again but perhaps within a new/old context. In the image below the prints of hands, the dots and the drawings of the animals are all working together to tell a story. It is a story that would have been very different when first told and as these images reach today's humans, new stories are shaped by the concerns of life now. 

From the caves at Lascaux

As these forms emerge within a contemporary framework, they arrive into the existing matrix of beliefs that society has about art, the body, the unconscious, belief, superstition, science, magic and religion. Old ideas become re-formed and re-read, the runes and symbols of ancient beliefs, such as those used by various shamanistic societies, now forming a texture out of which emerges new beliefs, truths are questioned and our faith in science begins to crack and at the same time it continues to produce wonders. It is into these cracks that my work tries to insert itself. Sometimes I can think of it as a contemporary answer to a loss of belief and yet also as a type of chaos magic, whereby it operates as a way to effect a change in thinking. All images are perhaps hallucinations, as they are never reality, but forms conjured up by our physiological makeup, as ways to help us make decisions as to what to do. Whether we think of art as a problem, echoing Plato's worry about mimicry or like Aristotle, see it as a way of rehearsing for life, we are faced with a never ending conundrum, one which I'm very happy to play with and offer yet another opportunity for others to join in with too.  Our inner lives are so rich, that science alone cannot depict them, but what these imaginary explorations can do, is to intimate the richness and celebrate the wonder of this strange thing called life.

Olivia Bax in Yorkshire

Olivia Bax has work on display in one of the Leeds City Art Gallery upper floor galleries. I have now looked at the work several times and earlier this week we went over to the Yorkshire Sculpture Park to see her work on display in the Weston Gallery, in the exhibition entitled, 'Olivia Bax: Double Take'.
I was particularly interested in her work because of its three dimensional relationship with two dimensional thinking. I'm always flitting between drawing, sculpture and making ceramics and the Leeds exhibition opened a window into how Bax had herself responded to two dimensional images by making 3D forms. 


It was fascinating to see how she had responded to still life imagery. The sculpture above being tilted in space to suggest a halfway house between these two modes of looking; a sort of two and a half D.
I am still working on how the imagined interior of the body could be visualised and in the wall mounted sculpture below I can see some possibilities for a direction my own art could take. For a while now I have been thinking of returning to papier-mâché as a way of working and 
Olivia Bax has been dyeing her paper pulp to integrate colour and form. I'm also considering using iron rods to support slightly larger possibilities and her use of materials was a useful reminder of how organic forms can be fused with the geometry of metal engineering.

Olivia Bax: Double Take

I was particularly impressed with the subtle colouration of the sculpture presented on the white shelf above and this has made me think about whether or not I could combine shiny ceramic glazed forms with the matt finish that papier-mâché has. Perhaps it's time to invest in a powerful blender that can cope with the demands of paper pulp production. 

Bax has also used wheels on her sculptures, and again this is something I have looked at before, as it is an interesting way of inducing both imaginary and real movement into sculptural objects. My sculpture 'How to move a plant in flower' in comparison looks dour, having a different type of formal coherence than her work and a much lower colour saturation.


Olivia Bax: Double Take


How to move a plant in flower

The Weston Gallery exhibition, also asked questions about the presentation of work. White geometric forms had been developed by Bax, ranging from skatepark influenced ramps, to shelving, that I thought echoed Haim Steinbach's work from the 1980s. 

Haim Steinbach

I wasn't convinced by the presentation, finding it beginning to overpower the work it was presenting. Perhaps what she was doing was setting up a 'battle' between formal approaches, a thought that came to me as I was exiting the exhibition. 

Just outside the Weston Gallery there is a shop which had four of Bax's small drawings in the window, entitled Battaglia VII, II, IX and XXX. Battaglia is the Italian word for "battle" or "fight," and battaglia is a form of Renaissance and Baroque programme music imitating a battle. I wondered if she was thinking more about the Renaissance form which is typically a madrigal for four or more voices where cannons, fanfares, cries, drum rolls, and other noises of a battle are imitated by voices. Something that I imagined as being very Cabaret Voltaire, the sound poem, being far older than we tend to think. The Baroque form is more often an instrumental depiction of a battle, perhaps her drawings are meant to be just that, depictions of visual battles. I always enjoy seeing other artist's drawings, as I like to think I can get a better insight into how they think. 




Olivia Bax: Battaglia VII, II, IX and XXX

There is much to glean from these two exhibitions and I shall no doubt return to Bax's work in the future, she is an artist that I had not come across before and from her drawings I can see that she has that restless searching eye, that I always think makes for an artist that will continue to make interesting work.

Art and Religion

Votives

I have been thinking more about the relationship that exists between art and religion. For instance the objects I have made that operate as votives, are linked to a need to work with a belief in their effectiveness. Even though these are what I describe as non-religious votives, or secular votives, people still seem to find them effective, as they allow the envisaging of change. A model of a frozen shoulder, allows someone to imagine their frozen shoulder pain, travelling out of their actual shoulder, to now inhabit a new shape, one designed to work as a pain receiver or taker away. In being able to now more actively imagine the pain moving out of their body, somehow this loosens the hold that pain has on the person with the problem. However, in order for the transfer to take place, it has also been found to be far more effective if some sort of verbal ritual is designed to accompany it. Even something as simple as: 

Pain, pain, go away

Move on out of me today

Pain pain, in my shoulder

You are banished to a holder

This simple rhyme, seems to operate not dissimilarly to a spell, it can be chanted in the mind or spoken out loud with others and in some way it seems to help by giving some sort of agency to the pain and with that agency a choice. But if I'm working with votive type objects, what does this have to say about the role of related disciplines such as magic and religion in all this? 

The longer I continue to make art that in some way I see as being able to operate as a way of transforming  a situation, by allowing people to work with an idea that has emerged out of the body/mind and is now an externalised thought, the more I wonder if the making of images would have been inseparable from the way communication with the 'spirit world' was maintained and established by early humans. In particular animist societies would not have had a divide between the two worlds, as they had a belief in the ability of the spirit to move between alive and inanimate things. There would have been no problem for an image to operate as a vessel or substitute for a body. It might become a portal or carrier, working to operate as a doorway into an alternative state of consciousness or as a messaging service, whereby information was passed between the physical and spiritual worlds. In fact visual images can simultaneously operate in all of these various ways and that is one of their unique properties. 

Bison: The Cave of Altamira in northern Spain

For instance an image of a bison could represent the spirit of an animal, become an entry point into the 'animal' as a spirit,  be a message about how the tribe wanted to think about a relationship with that animal, perhaps to establish a communication channel with the many dead animals that had been part of successful hunts, or to make sure the bison was going to continue to be seen alive again during the following hunting year, so that future hunts would be successful. But perhaps the image could be a portal through which a human could pass to become a bison. To be a bison is to know a bison and to know a bison is to be able to hunt it much more effectively. The bison is also a powerful beast and may have been envied as to its strength and resilience, perhaps in some ways it also becomes a figure of worship, an entity whereby a human may want to establish an invisible communication channel, down which the bison entity could pass on aspects of its strength and virility. For a hunting community a bison was their lifeblood, its life was interwoven with theirs as was its death. The mystery of a bison's reappearance each year, probably at similar times and places would have to be explained somehow, also any bison glut or scarcity would have to be responded to, and humans had imagination. Therefore they would imagine why a bison might not reappear. It might be simply fed up in that it had not been appreciated properly last year or it might have encountered a much fiercer predator, in imagination perhaps a creature much more lion like. Gradually a link between ideas, perhaps thoughts communicated around the first warming night fires, would help give form to the materials surrounding early peoples; initially a shape like a bison might have been seen in a rock form lit by a fire, then at another point in the shape of some clay fingered whilst people talked around that fire, or outlined in burnt wood, as a stick was taken out of a hearth.

The Lion Man of Hohlenstein-Stadel 

 The Lion Man of Hohlenstein-Stadel is a very early example of an animal / human hybrid and it would take hundreds of hours to carve images of that sort, therefore the idea must have been long established by then, that material objects could be used as important intersessions in the relationship between humans and what I shall call the spirit world. Whether the lion man carving operated as a doorway, a substitute, a communication channel or in other ways we will never know, but as a physical object it carries an idea of transformation and hybridity that clearly connects humans and lions. Perhaps it was used to channel down a lion's strength and ferocity before setting off for a hunt, or to give to a member of the tribe as an award of some sort, anointing them with the title of 'lion' because of their prowess in battle, the lion-man being part of a symbolic transfer of power. Rulers like to be seen to be anointed and appointed by a God of some sort and this might have been an object taken from a very early example of a ritual process whereby power was both acknowledged and passed on. In all of these cases the image/object lies at the centre of the process and allows for thoughts to be shaped and held in certain forms. I'm also sure that a narrative would have surrounded this object, its function would have been 'talked out', amongst those present. Whether a shaman held court, or it was more a collective experience, who knows, but some sort of ritual collective experience would have been woven around the object, its significance understood by all present. This could be what we would eventually think of as religion. 

My questions in relation to this, are in what way is the visual materialising of thought related to the structures within our brains that help visualise information and are these structures and the processes they support in some way responsible for our religious feelings? If so there would be a necessary connection between the visions made and the spiritual feelings invoked. 

In his book, Paleopoetics, Christopher Collins tries to trace our collective history back much further than when the lion man was being used. He begins by observing that before verbal language, early humans must have had ways of dealing with complex understandings of the world. He refers to Jacob Von Uexküll's idea that each creature's own 'unwelten' or phenomenal world is different. This implies that living beings perceive their worlds in terms of species-specific, spatio-temporal, "self-in-world" subjective reference frames. So if we go back to the special nature of our perceptual systems, visual information is passed from each eye into the brain via the optic nerve. Once information reaches the visual cortex, (Ungerleider and Mishkin, 1982) argued that it is then split into two neural streams, one going to the parietal lobe, (the dorsal stream)  the other the temporal lobe (the ventral stream). The dorsal stream being associated with spatial perception, the ventral stream being associated with object recognition. The ventral stream essentially transforms visual information into representations that hold form or shape, in such a way that things emerge out of the undifferentiated colours and shapes of our complex environments, the brain's processing giving importance to things that hold significance to us. For instance although in our early history there would be no word for ripe fruit yet, the brain would still need to be able to associate the changing colour of fruit with its readiness for eating. That old natural symbol is still in operation and I believe it may have something to do with why we still need to make art, part of our old brain is still stimulated by visual alerts, even manufactured ones like paintings and drawings, triggering our ancient neural pathways, a process that we now call tacit knowledge, instinct, intuition or gut feeling. 

Higher order visual pathways

However the dorsal and ventral streams don't operate separately, they work together. They are like two highways that have multiple connecting roads between the two. As the brain develops, more connecting roads form as information gets exchanged. As more information gets exchanged, the system becomes increasingly efficient at identifying and interacting with objects in the visual world. The dorsal stream never acts alone, nor does the ventral stream. Instinct and rationality become entwined. 


The interconnections between dorsal and ventral pathways

In fact, where, what and how are intermingled and cross reference each other, (Sheth and Young, 2016), one element of the picture is always being checked out by another, until a 'something' emerges out of the complicated moving background jumble of scanned perceptions. The visual materialising of a thought, as in a drawing, could be regarded therefore as following a similar process. Could, I begin to think, certain types of drawings be regarded as models of how visual perception itself operates?
What if you see a shaking of the leaves of a tree. Sometimes it's obvious what is causing the shake, but at other times it's not. Is it a creature moving along a branch? Is it the wind? But what if you can see no animals and you feel no breeze? Your imagination will quickly come into play. It's complex but simple at the same time. Interconnected in parallel with the “what” of the ventral pathway, is the dorsal stream, 
the vision for action stream of "where” and “how”. The guidance of actions is decided upon alongside having to locate associated objects in a space. Do you want to grab or avoid these objects in space, i.e. stay and see what's going on or run away? In fact all of the brain’s lobes participate in vision, and multiple visual centres are located throughout the brain, but all of them are as they become attuned to each other, subject to bayesian inference, that statistical method that updates the probability of a hypothesis as more evidence or information becomes available.

Instinct is the stuff of chimpanzees as well as humans, so how does it relate to the forming of religions? I think its got to do with trust and belief. In order for all that dorsal and ventral pathways stuff to work at the speed it does, we cant actually think about it, we need to trust in our instincts. Gut feeling for one reason or another seems to work for us. But what happens when we develop higher order thinking mechanisms such as inductive logic? They are slower, but in their step by step logic, they can stand up to scrutiny and you can decide whether or not the logic is 'true' or not. Hence we have scientific reasoning. Of course this works well for us, but as we have seen in the past it can also lead not to war, but to an ability to wage war with an efficiency that becomes inhuman. As a necessary balance, I believe that art still in many ways allows us to use instinct or an internal sense of rightness, when either trying to solve non scientific problems or to simply re-engage with the world. As an artist you develop a belief in your feelings for materials, in the particular way your body moves, for certain sounds or ways of making images, but you don't have to know what these things mean; you operate using tacit knowledge.


Ramsey Dukes: Diagram of the relationships between disciplines

Looking at the magic researcher Ramsey Dukes's diagram, you can see the relationship between art and religion, both emerging from a belief in intuition, but religion has to work with more thinking than feeling, i. e. it needs structures within which to work, such as codes of behaviour as set out by the various religions or the stories told by a shaman to make sense of the spirit world that shamanic practices might help you enter. Hence religion needs a certain amount of inductive logic, so that followers can be shown reasons for the truth of their beliefs. Art still operates as a more 'open' portal into intuitive logic, which is why it is both useful to religion and at the same time a problem; because all visual images are open to interpretation. According to Dukes, magic is simply 'what works', using any combination of logic, symbols, rhetoric, atmosphere, influence etc. to effect an impact on others. Art in many ways 'bleeds' into both religion and magic, its edges of 'effect' being formed by whatever surrounding narratives are being told. 

For instance the image below is a meditation on paper, made by people who were Indian tantric mystics. The image operates as a portal for the mind and is for individual contemplation.

Indian tantric art

The black square by Malevich, below, was hung high up in the corner of a room, the traditional spot for a sacred Russian Orthodox religious icon, signalling a shift from religious worship to pure, secular artistic devotion.

Malevich

The 'Ultimate Painting' 1963 by Ad Reinhardt, is an example of 'Art-as-Art' or 'Art for Art’s Sake'. Reinhardt insisted on separating art from everyday life, trying to erase any content other than the art itself. He described the work as "a pure, abstract, non-objective, timeless, spaceless, changeless, relationless, disinterested painting"

Ultimate Painting' 1963 by Ad Reinhardt

However Reinhardt's paintings have been interpreted as meditations on death, the ultimate end of things and have also been seen as portals into other worlds. Show any group of people a black square and ask them what it means and you will get a wide range of answers, its meaning to each individual being dependent on its use value. 
I have recently completed a commission for a church, the work I installed created a situation that I was able to evaluate in real time, as I was taking tours of the graveyard within which the work was set. 
St Michael's Church installation (Details)

I had made large ceramic ears, installed as portals, many of which were embedded into trees, so that people encountering them could both listen to nature and talk to the trees. But some were free standing, such as the one above, a two sided form that now replaced a former stone cross that had been broken off many years ago. One, (left) was designed to echo the form of the virgin Mary, the other side a more  'normal' ear. It was interesting to hear what people said as they encountered the work, those with an already Christian disposition 'saw' the virgin in the ear, those who had to be shown the idea, mostly then 'got it'. I made the ear as a portal, or ear trumpet, that could enable people to speak to the dead. When we attempted to speak to Alice via the ear below, we were all aware that the graveyard had been covered by brambles for many years. Alice's memorial was broken; no one had put flowers on her grave for many years. Alice had died young and she had had no words of comfort given to her since her grave had been abandoned. To then 'speak' of her, to address her directly was an emotional moment. Some people were brought to tears as a few words were said. A few words of comfort to let Alice know that she was being acknowledged by people who had never known her, but who on this day, in the Autumn of 2026, were minded to try and comfort her. 

An ear for Alice

The fact that an object could be a portal between the mundane world of today's busy city and the spirit of a long dead child did seem to work, an idea as ancient as the one whereby an image of a bison, allowed early humans to communicate with its spirit.

Imagined and neurobiological maps

 (c) Lee lab

I am often creating imagined maps of the body. But I'm also very aware there are other approaches to visualising the internal body and one I'm often thinking about is the mapping process that neurobiological scientists are constantly developing as they attempt to follow the complex interconnections that the body's neurological systems undertake.

Wei Chung Allen Lee of the Harvard Medical School research team that are looking at mapping the body's neurological systems has this to say, “The brain is structured so that each neuron is connected to thousands of other neurons, and so to understand what a single neuron is doing, ideally you study it within the context of the rest of the neural network. In essence, the structure of how our neurons are wired is our “self,” and connectomics is the key to understanding this structure." My lab is interested in... how those neurons are active within the functioning circuit. We do this in the context of behaviour, ranging from making decisions to executing actions."

However it is the fruit fly that is providing the material for the research and initially what we are looking at is a map of drosophila.  

The fruit fly: Drosophila

As an animist, I wondered what it must be like to be immersed into the fruit fly's umwelten or subjective reality. The project had revealed that complex behaviours and motor control were driven largely by distributed local neural circuits throughout the body rather than a single top-down brain command centre. I began to wonder how similar we might be to a fruit fly, how many of our own behaviours were the result of distributed local circuits. 

As a result of all this work the first complete synapse-level wiring diagram of the entire adult fruit fly central nervous system, uniting brain and nerve cord connectomes has been published and the images are wonderful.


The Male CNS dataset covers the fruit fly’s brain and ventral nerve cord.

Artificial deep neural networks, computer models inspired by the human brain that use multiple layers of interconnected processing units, to learn complex patterns from raw data, are used to extract information about cells and their connectivity from massive datasets. That being so, I do think there is room for some doubt on how the final pattern works, as the computer models will be looking for certain patterns and perhaps not others, but it does all seem pretty impressive.  The fruit flies, pretty impressive in themselves, are not the only animals used, mice also provide models used to help study the basic principles of how neural circuits are built and operate, thus helping to find out how neural networks are connected to each other to perform the different computations that underlie behaviour. People, flys, mice and artificial neural networks, all deeply interconnected, as they weave a new set of patterns. 
As I read about these things I was reminded of my time in Gothenburg, where I became very aware of how monkeys were used in the development of new spinal injury treatments. At the time I wrote about how Bruno Latour used the image of a constant fermentation that arises as a physical/chemical/quantum/emotional/psychological and economic mix, all being part of the currents that flow within vast energy seas of interconnected information, but the bit we think we swim in tends to be experienced as being very shallow and we easily forget its depths.  Therefore we need to be reminded that amongst many other things, we are beholden to dead animals, who have given their lives for our research. As a child in the 1950s the short prayer we had to say before meals, whereby we thanked God for there being enough food to eat went,

“For what we are about to receive,
may the Lord make us truly thankful. Amen.”

That small moment, whereby as a child I had to think about where the food came from was important. It would seem to me that we need something similar as a recognition of the role of other creatures in providing us with information that helps us to think about how we are ourselves constructed. The images below are provided curtesy of a mouse and we can think of them as visual prayers or simply that they look magical.

An image of two granule cells (light and dark blue) connected to three mossy fibers (red, pink, and yellow) in the mouse cerebellum.

As a small token of appreciation, I have written a short poem; like the one about being grateful for the food we have, it is targeted at children, my 1950s brain, still wired in a particular child focused way and yet at the same time I'm mindful that magic practices often require a rhyming spell in order to make them effective. Even Sooty had to chant, "Izzy wizzy, let's get busy!" before his spells would work, all of which is part of the life soup, or witches brew,  that consists of the physical/chemical/quantum/emotional/psychological and economic mix that Bruno Latour was thinking about. 

All creatures of the earth and sky,
Of tiger, monkey, fish and fly.
Please listen to my humble prayer.
My endless, heavy debt of care.
For creatures of the land and sea.
Who've given up their lives for me.

So how does this mapping of 
body's neurological systems relate to what I'm doing as a creator of imagined interiors of the body? Studies have shown that within an area of the brain known as the somatosensory cortex there exists a map of the body, with different regions corresponding to different body parts. These maps are responsible for processing sensory information, such as touch, temperate and pain, as well as body position. For example, if you touch something hot with your hand, this will activate a particular region of the brain; if you stub your toe, a different region activates. For decades now, the commonly-accepted view among neuroscientists has been that following amputation of a limb, neighbouring regions rearrange and essentially take over the area previously assigned to the now missing limb. But this has presented a conundrum. Most amputees report phantom sensations, a feeling that the limb is still in place, this can also lead to sensations such as itching or pain in the missing limb. Also, brain imaging studies where amputees have been asked to ‘move’ their missing fingers have shown brain patterns resembling those of able-bodied individuals. I.e. the body itself has an imagined map, one that remains in place, even if parts of the body are no longer there. In my own imagination therefore, the imagined body map I internally possess myself, becomes merged with the imagined body that I am over the years constructing and externalising, not only of my own interoceptual feelings, but of other people's.

The mystic interior

The more I talk to people about their pain, the more I realise it is a complex issue. For instance, sclerotomal pain is typically felt as something deep down or dull and it is poorly localised; people often describe it as “achy” or “boring”. In contrast: dermatomal pain, that connected to an area of the skin linked to sensory neurons from a particular spinal nerve, can be sharp and burning and well defined, as when a spinal nerve root is compressed, irritated, or inflamed (such as from a herniated disc, spinal stenosis, or a viral infection like shingles). This is closely linked to myotomal pain, as felt by a group of skeletal muscles supplied by a single spinal nerve root; the pain symptoms occurring when a nerve root in the spine is compressed, irritated, or injured. This time a pain might feel crampy and be associated with restricted movement or fatigue. There also exist maps of acupuncture points that treat deep connective tissue pain as well as sclerotomal maps that assist clinicians in tracing the origin of pain that doesn’t follow a typical dermatome or myotome, such as pain around the shoulder blade from lower cervical irritation or deep pelvic pain from sacral sclerotome involvement. I. e. where pain seems to be in the mind map, is not necessarily, where an actual problem lies in the body.  It is as if the body can tell lies or at least stories that are hard to read or understand. These issues chiming with my own continuing struggle to visualise the sensations I have when inhabiting this old body of mine. These other maps all operating as parallel forms of awareness, that lie in that area of associated attempts to visualise the internal body from the point of view of other disciplines. My imagined interoceptual maps acknowledge their existence and participate in diagrammatic dialogues with the observer but the area of overlap is one of intuitive feeling and never one of scientific verisimilitude, as much about diagrams taken from magic rituals as maps of Yorkshire's underlying geology.
