Spatial representation in the brain

Nice video explanation of hippocampus and episodic memory

Mapping of a non-spatial dimension by the hippocampal–entorhinal circuit

See here. Individual place cells correspond to places/states. However, their activation patterns correspond to the places/states that one is most likely to visit in the future (in a discounted way, see paper). This is the Successor representation

Dynamic updating of hippocampal object representations reflects new conceptual knowledge

Hippocampal replay

Replay of remembered or imagined trajectories

We will probe the role of hippocampal replay events in learning the structure of state spaces by assessing whether the frequency and content of such events is influenced on encountering changes in the maze structure, and test for a causal role of such events in structure learning using closed loop optogenetic inhibition of the hippocampus during sharp waves.
