Abstract Key questions for understanding hippocampal function in memory and navigation humans are the type source of visual information that reaches human hippocampus. We measured bidirectional pairwise effective connectivity with functional magnetic resonance imaging between 360 cortical regions while 956 Human Connectome Project participants viewed scenes, faces, tools, or body parts. developed a method using deterministic dynamical graphs to define whole networks flow both directions their over timesteps after signal is applied V1. revealed ventromedial “Where” network from V1 via retrosplenial medial parahippocampal scene areas hippocampus when scenes viewed. A ventrolateral “What” V2–V4, fusiform face cortex, lateral region TF faces/objects There major implications computations vs rodent navigation: primates fovea highly processing process about location objects, landmarks whereas rodents representations system mainly place where individual located self-motion places.
