Geometric determinants of the postrhinal egocentric spatial map - Cell.com

TL;DR Rat postrhinal cortex neurons encode environmental geometry in an egocentric reference frame. The study explores if these neurons encode high-level global parameters or respond to the bearings and distances of nearby walls.

Animals use the geometry of their local environments to orient themselves during navigation. Single neurons in the rat postrhinal cortex (POR) appear to encode environmental geometry in an egocentric (self-centered) reference frame, such that they fire in response to the egocentric bearing and/or distance from the environment center or boundaries. The study investigates whether these neurons truly encode high-level global parameters or are simply responsive to nearby walls by recording from POR neurons in rats foraging in environments with different geometric layouts and modeling their responses based on either global geometry or local boundary encoding.
