I understand that evolution incorporated arbitrary qualia into the default network to inform consciousness (the largest cranial global processing information subnetwork) about properties and qualities of the body in spacetime. However, how does the feeling in my toe know to appear near my toe when nerves there are stimulated? Is this an illusion, and there is extraneous processing that matches the visual stimulus of me looking at my toe and the tactile stimuli of someone touching it to make those qualia feel related, even localized in the same area in space?
What if my somatosensory cortex was moved to my stomach (say all dendrites and axons were chopped off and were replaced with wireless hubs that signaled to the newly transplanted somatosensory cortex in my stomach). I would presumably experience no change in consciousness, which indicated localization of qualia is not achieved by the spatial embedding of the neurons, but by their graph-theoretic interconnection.
If I swapped the information processing (in some information-theoretic sense, say graph-dynamics) associated to the smell of strawberry (it's much more complicated than that but just go with it for a second) with the brain's processing of thermal information from afferent skin sensors, would I appear to feel the smell of strawberry all over my body when it's cold and the feel of cold in my nose when I smelled strawberry? I am excluding affect swap here so the qualia of strawberry smell now feels unpleasant like cold and the qualia of cold feels pleasant like strawberry smell.
Now what if in mad science I permuted the thermal sensors all over my body? Say my foot and hand neurons got swapped (say through a nanobot intercepting wireless relay). Would my hand feel cold when my foot is immersed in ice and vice versa? This would indicate these qualia are processed in consciousness in the brain rather than at the afferent sensor sites.
For bonus credit: How does this relate to phantom limb syndrome? Are there other observed processing defects that lead to faulty localization? E.g. Out of body experiences, certain particularly nasty mental disorders like dementia, rewiring of somatosensory map due to stroke, that engineering dean who wanted his arm chopped off (I forgot the name but I heard this from V.S. Ramachandran)
Second bonus credit: I've read "butterflies" in your stomach are serotonin releases in the enteric nervous system. Doesn't consciousness have to be informed of this release for you to feel it? If not, how do disconnected information graphs allow you the cohesive ability to feel in love?
