Replay of procedural experience is independent of the hippocampus

We use an unsupervised sequence detection algorithm to demonstrate, for the first time, replay of procedural memories in the striatum and that this replay is hippocampus-independent.

A generative model of the hippocampal formation trained with theta driven local learning rules

A model of the hippocampal formation where theta-band oscillations and local error-correcting Hebbian learning rules train weights it analagous to a wake-speel algorithm. This bioplausible hippocampal model replicates key cognitive functions including path integration.
