High-conductance states and consciousness


Recommended Posts

Are there any theories which directly relate these two, that this feature of neurons could be necessary for consciousness to emerge? I've read high conductance states are found in thalamocortical radiations and I vaguely remember thalamocortical radiations being implicated in consciousness in another theory (dynamic theory?).

trying to find a paper on dynamic core hypothesis (not a theory my mistake) i can link for you to read in full and having a bit of trouble. one of the authors is giulio tononi.

 

edit: found one http://wiki.dxarts.washington.edu/sandbox/groups/general/wiki/6746a/attachments/2b0a6/Tononi-Edelman%20Science-1998-.pdf?sessionID=a4ebd3f43afa7fffb5c21749aed42be63973d1df

I'm sorry. I'm too busy at the moment to help you with this. There should still be at least one or two other neuroscientists around here. Otherwise, there are biologists and people with some psychology and philosophy background.

Presumably by high conductance you are referring to the process of myelination, in which case yes you could argue compared to patients with MS for example, normal myelination improves cognition and perhaps consciousness.

 

But my understanding of consciousness - defined as wakefulness, having a normal mental state, and ability to follow instructions, is more of a function of structural and functional integrity to certain sets of neurons in the brainstem - for example the reticular formation. If you were to reduce conductance of the reticular formation neurons you may reduce consciousness, but almost all pathologies to the brain stem would lead to the same outcome of loss of consciousness, it's not solely limited to a problem with neuronal conductance.

 

I hope this helps!

I think there is a lot more to vision and consciousness than we understand. Philosophers of science are on the right track, but I sometimes wonder if the scientific method that we use is limited ("measurement problem" issue). However, there is still the whole mathematical basis of vision, such as related to Fourier transformations, which makes me a strong believer in the mathematical universe hypothesis. With that said, I think "consciousness" can be related to a mathematical construct. I covered something like this on philosophyforums.com before it was hacked and wiped.
