I came across a nice summary of a few neocortical plasticity mechanisms that some deep learning researchers are trying to incorporate in their models.
Most of it reminded me of the HTM neuron described in the beginning of the BAMI document.
Some additional info may interest the community.
On a side note, the paper put an emphasis on Martinotti interneurons with a functional role that seems similar to the HTM spatial pooler. But I was thinking that the HTM SP was modeling the role of basket and/or chandelier cells, not Martinotti cells. Is it something different?
Martinotti neurons, which are activated by such cliques of pyramidal neurons, and subsequently inhibit pyramidal dendrites (Silberberg and Markram, 2007) provide well-timed inhibition to block further NMDA spikes (Doron et al., 2017), and put a limit on the maximal pyramidal clique size, but also suppress activation of competing cliques (e.g. Winner-take-all (WTA) dynamics).
The paper is available here (short read)
