DOI: 10.3389/fncir.2022.924016
Abstract: Grid cells or grid-like responses have been reported in the rodent, bat and human brains during various spatial and non-spatial tasks. However, the functions of grid-like representations beyond the classical hippocampal formation remain elusive. Based… read more here.

DOI: 10.3389/fnhum.2021.620056
Abstract: 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… read more here.
