Parasubiculum

The parasubiculum is a retrohippocampal isocortical structure, and a major component of the subicular complex. It receives numerous subcortical and cortical inputs, and sends major projections to the superficial layers of the entorhinal cortex (Amaral & Witter, 1995). It is postulated to play an integral role in spatial navigation, including place cells (Chrobak & Buzsaki, 1994; Taube, 1995).
