Hi Jeff, I've been following your work for a few years now and am very excited to read your latest thoughts on the TP mechanism. I was hoping (a little belatedly) to clarify some aspects. Regarding the paragraph:
"As a general rule, sub-cortical neurons that generate behavior have split axons. One branch generates the behavior and the other is sent to the cortex. If the cortex didn't get copies of motor commands you couldn't function. Every time you moved your eyes or turned your head it would appear as if the world was spinning and shifting." In previous descriptions of the biology in the white paper and in the literature (such as Sherman 2007), a signal is passed a) to motor regions and b) to higher cortical regions via a thalamic relay. How does your new approach fit into this biological understanding? More specifically: - Is this the copy of the motor command that is input to Layer 4? If not, is it additional or an alternative understanding? - Does the connectivity of the splitting axons as described, occur between layers as you move up the hierarchy, or just at the sub-cortical to cortical level?
