I am studying temporal memory and I understand its function, but I still have doubts on some points. The main question is in relation to the receptive field of the distal segments, I understand how it works in the SP between the proximal segment and the input space, but I still cannot see how it works in the lateral connections between the mini columns. The HTM theory does a simplification, where the receptive field would be all the winning or active cells of t-1? I believe that my doubt is related to my lack of knowledge about axonal projections of neurons in the TM layer, could anyone clarify me?
Another point is the synaptic learning of the distal and apical segments, is it pure Hebbian learning? This confuses me because of the modulatory characteristic of these segments, for the learning of Hebbian to work is not necessary a greater relationship between dendrite activation and the neuron action potential?
