Overview over connectivity findings. Anatomical connectivity studies in animals and functional connectivity studies in humans converge on the following: bilateral connections convey spatial information between dorsal visual regions, parahippocampal cortex (PHC), posterior-medial entorhinal cortex (EC), and hippocampus (HC), and object information between ventral visual regions, perirhinal cortex (PRC), anterolateral EC, and HC. Importantly, these parallel circuits are interconnected on the level of PRC-PHC and EC; and some connections skip levels. Not depicted are differential connectivity patterns between EC subregions and HC subfields, and intrinsic connections within subregions. See “Connectivity and functional implications” Section for details. A, anterior; P, posterior; L, lateral; M, medial.
