A journey from neocortex to hippocampus

Abstract

In the mid-1960s, it was generally agreed that the engram, the neural trace of previously experienced events, must be encoded by Hebb-like neurons in which synaptic efficacy could be modified by activity. Here, I describe my attempts as a PhD student at McGill University, Montreal, to find rules governing cortical plasticity in the neocortex, and having failed, why the hippocampus seemed to offer a far better prospect.
