Notes: Thomson's "Neocortical Layer 6, A Review"

@jhawkins ,

From my reading I suspect that the L4 projections serve to establish and maintain thalamocortical resonance and the deep layer projections serve as a supervisory circuit for the feedback direction pathways.

See references 5 and 8 in this post:

HTMs, Time Locking, and Neural Oscillation (Brain Waves)

The basic HTM theory describes region updates as synchronous, with the SDRs as a static presence during each cycle evaluation; updated whole throughout the region after each evaluation. It is implied in all discussions for predictive dendrite segments (SDRs) that there is a “before” and “after” in regards to global states for the local region; the processing of the SDR neurons in a region could be considered as the evolution of the current region state to the next state as a coherent whole.
