A population code for semantics in human hippocampus.

Electrophysiological dissociation of human posterior cingulate cortex contributions to value- and memory-based decision-making

Dorsal but not ventral PCC engagement was identified as a domain-general interface between evaluative and mnemonic systems, identifying dorsal PCC as a domain-general interface between evaluative and mnemonic systems.

Neural geometry in the human hippocampus enables generalization across spatial position and gaze.

It is found that neurons have mixed selective responses that map the positions of self, prey, and predator, as well as gaze direction, which suggest that hippocampal spatial knowledge is structured as a family of geometrically related manifolds that can be related through simple linear transformations.

Neural basis of compositional control

Behaviour of human participants in a prey-pursuit task reflects dynamic blending of goal-specific control policies, with hippocampus estimating latent states, anterior cingulate cortex orchestrating policy switches and orbitofrontal cortex supplying value-based contextualization rather than driving continuous policy up...
