Successor-like representation guides the prediction of future events in human visual cortex and hippocampus

Early visual cortex (V1) and hippocampal cortex represent a predictive map of the visual world akin to the successor representation.

Nice to see a resurgence of predictive coding (now called successor representation). We discovered this in hippocampus 25 years ago! Remarkably, place cells develop predictive coding even in highly familiar environments, everyday! Also, some place fields turn on abruptly after a few trials, even when the rat did the same simple task, walkin on the same narrow linear track, for weeks!

Expansion and Shift of Hippocampal Place Fields: Evidence for Synaptic Potentiation during Behavior

Rat hippocampal neurons fire in a spatially selective fashion [1]. We show that place fields enlarge (by 75%) and shift (by 1.4cm) in a direction opposite to the direction of movement of the rat, within a few traverses of a route, even if the environment has been...
