Hippocampal Replay

Neurobiological process modeled by REM sleep in active inference; re-running past outcomes under new model

Neighborhood — ranked by edge-count

concept

REM Sleep
associated_with
Associated with reevaluation of posteriors under new model structure after non-REM synaptic regression

cosine ≥ 0.65 · no typed edge

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

Hippocampusconcept0.810
Brain region corresponding to the memory/conjunction component in TEM; memory neurons resemble place cells.
Hippocampal representation of related and opposing memories (McKenzie et al., 2014)concept0.767
Experimental evidence that hippocampal neurons respond to more than two task variables; motivates multi-input extension of TEM-t.
Hippocampal Formationconcept0.758
Brain region complex whose spatial representations TEM-t is shown to replicate.
Hippocampal Indexing Theoryframework0.750
Theory that hippocampus provides an index binding together cortical patterns across different brain regions; TEM-t is shown to instantiate this.
The hippocampus as a predictive map (Stachenfeld et al., 2017)concept0.733
Graph representation model of hippocampus; related work category 2.
Experience Replaymethod0.728
RL technique using episodic memory to improve sample efficiency; used in some game-playing agents.
The hippocampus as a spatial map (O'Keefe & Dostrovsky, 1971)concept0.721
Original discovery of place cells; the neural phenomenon TEM-t memory neurons resemble.
The Hippocampal Indexing Theory and Episodic Memory (Teyler & Rudy, 2007)concept0.713
Original paper on hippocampal indexing theory; TEM-t is shown to instantiate this theory.
