SDRs in HTM model synchronized activity of a few cells in a layer of a cortical column, where activity could be a single output spike or a brief burst†. It seems that spike transmission time in long-range connections must result in some desynchronization?
I’m interested in whether this is seen as an issue in TBT, where long-range cross region connections seem to have a greater significance than in the traditional hierarchical model? Could temporal coding (spike bursts, produced by a single neuron or a cell assembly, in which the pattern of inter-spike intervals is significant) play a part in TBT models?
Also, the frameworks paper proposes that L5 displacement cells multiplex representations for movement vectors and object composition: would welcome more explanation/discussion of this.
