Topic: environmental boundaries

Efficient spatial navigation in complex environments relies on the construction of an egocentric cognitive map. Recent studies have reported that subpopulations of excitatory neurons in the granular retrosplenial cortex (RSC) are selectively activated at specific distances and orientations relative to environmental boundaries and vertices, tuned by the heading directions of the animal, to perform egocentric vector coding of the environmental geometry. However, the neural circuit mechanisms explaining how egocentric representation of vertices and boundaries emerges are yet unknown. One possible

The subiculum (SUB) is the major output structure of the hippocampus. It is involved in spatial learning and memory and it contains neurons that exhibit different electrophysiological and functional properties. This variety might suggest the involvement of the SUB in multiple circuits supporting distinct cognitive processes. The diversity in projection targets for different cell types further supports this notion. Our study aimed to investigate the electrophysiological properties of neurons in the subiculum, their spatial modulation response, and the relationship between them. We implanted sil
