Abstract representations emerge in human hippocampal neurons during inference.

ABSTRACT: Humans have the remarkable cognitive capacity to rapidly adapt to changing environments. Central to this capacity is the ability to form high-level, abstract representations that take advantage of regularities in the world to support generalization¹. However, little is known about how these representations are encoded in populations of neurons, how they emerge through learning and how they relate to behaviour^2,3. Here we characterized the representational geometry of populations of neurons (single units) recorded in the hippocampus, amygdala, medial frontal cortex and ventral temporal cortex of neurosurgical patients performing an inferential reasoning task. We found that only the neural representations formed in the hippocampus simultaneously encode several task vari
