As rats learn to search for multiple sources of food or water in a complex environment, they generate increasingly efficient trajectories between reward sites. Such spatial navigation capacity involves the replay of hippocampal place-cells during awa

A computational model for spatial cognition combining dorsal and ventral hippocampal place field maps: multiscale navigation

Autor: Alfredo Weitzenfeld, Jean Marc Fellous, Pablo Scleidorovich, Martin Llofriu

Publikováno v: Biological Cybernetics. 114:187-207

Classic studies have shown that place cells are organized along the dorsoventral axis of the hippocampus according to their field size, with dorsal hippocampal place cells having smaller field sizes than ventral place cells. Studies have also suggest
