Abstract
Map-Like Representations of an Abstract Conceptual Space in the Human Brain.
Highlights
Much of higher cognition involves abstracting away from sensory details and thinking conceptually
How do our brains learn and represent such abstract concepts? Recent work has proposed that neural representations in the medial temporal lobe (MTL), which are involved in spatial navigation, might support learning of higher-level knowledge structures (Behrens et al, 2018; Bellmund et al, 2018)
A range of MTL neurons such as place cells, grid cells, and headdirection cells may support the ability to mentally “navigate” through conceptual spaces. This extends the original proposal by Tolman (1948) that people construct “cognitive maps” that support broad psychological functions, and offers the exciting potential of understanding the cognitive processes that underlie category learning, reinforcement learning, and spatial navigation under a single unified framework
Summary
Much of higher cognition involves abstracting away from sensory details and thinking conceptually. Recent work has proposed that neural representations in the medial temporal lobe (MTL), which are involved in spatial navigation, might support learning of higher-level knowledge structures (Behrens et al, 2018; Bellmund et al, 2018).
