thalamus

The inputs one feed in through the eyeballs and thalamus play a large role in the dynamical state.

It also seems more practical to plug the signal "into the cables" than to try to pass information through the complexity of the eye. In which case I believe it is the thalamus[1] that we should aim to plug into.

Cheers to the team for sure!I have done a little bit of corticofugal recording where we'd stimulate thalamus and record from cortex, and i was impressed enough at that.

If you had bits of your brain replaced with identically functioning machinery, would you still be you?What if you had your whole brain replaced piecemeal like that?What about if you had a prosthetic thalamus or visual cortex?

"... shown that many difficulties associated with dyslexia can potentially be traced back to a malfunction of the medial geniculate body in the thalamus.

Their high density in the thalamus, striatum, limbic system, and neocortex suggest that cholinergic transmission is likely to be critically important for memory, learning, attention and other higher brain functions.

This wiring pattern is much more difficult to experimentally measure than simply counting neurons because it would involve flashing tiny, contrast-y dots of light in front of a fixated mammal while poking an electrode around in the thalamus.

A single-photon emission tomography study6 found increased serotonin transporter availability in the thalamus, but not in the raphe nuclei, in patients with SAD relative to healthy control individuals.

Now that I think about it, perhaps an even better definition of a physiological pixel would be a functional measure: the number of distinct, electro-physiologically measured center-surround fields in the thalamus.

Some areas are tuned to react to points, some to bars, some to grids, some to movement, some to rotation, etc. Perhaps it would be simpler to make the comparison in the other direction: "How intricate do I have to make this visual scene to fully exercise the perceptual abilities of grating-sensitive neurons in the Lateral Geniculate Nucleus of the thalamus.
