Representation of navigational affordances and ego-motion in the occipital place area.

ABSTRACT: Humans effortlessly use vision to plan and guide navigation through the local environment, or "scene." A network of three cortical regions responds selectively to visual scene information, including the occipital (OPA), parahippocampal (PPA), and medial place areas (MPA)-but how this network supports visually guided navigation is unclear. Recent evidence suggests that one region, in particular, the OPA, supports visual representations for navigation, while PPA and MPA support other aspects of scene processing. However, most previous studies tested only static scene images, which lack the dynamic experience of navigating through scenes. We used dynamic movie stimuli to test whether OPA, PPA, and MPA represent two critical kinds of navigationally relevant information: navigational affordance
