Abstract Reorientation, the process of regaining one’s bearings after becoming lost, requires identification of a spatial context (context recognition) and recovery of facing direction within that context (heading retrieval). We previously showed t

When people view an object, they can often guess the setting from which it was drawn and the other objects that might be found in that setting. Here the authors identify regions of the human visual system that represent this information about which o

Landmark objects are points of reference that can anchor one's internal cognitive map to the external world while navigating. They are especially useful in indoor environments where other cues such as spatial geometries are often similar across locat

Adaptation is thought to improve discrimination by pulling neural representations of similar stimuli farther apart. Here, the authors separately show that adaptation to a 3D shape class leads to better discrimination performance on similar shapes, an

In familiar environments, the firing fields of entorhinal grid cells form regular triangular lattices. However, when the geometric shape of the environment is deformed, these time-averaged grid patterns are distorted in a grid scale-dependent and loc

A lost navigator must identify its current location and recover its facing direction to restore its bearings. We tested the idea that these two tasks--place recognition and heading retrieval--might be mediated by distinct cognitive systems in mice. P

Summary We propose a unified explanation for the diverse distortions in time-averaged activity of grid and place cells observed after environmental deformations. In our account, input from border cells resets the spatial phase but not the spatial sca

Biologically inspired deep convolutional neural networks (CNNs), trained for computer vision tasks, have been found to predict cortical responses with remarkable accuracy. However, the internal operations of these models remain poorly understood, and

The parahippocampal place area (PPA) is one of several brain regions that respond more strongly to scenes than to non-scene items such as objects and faces. The mechanism underlying this scene-preferential response remains unclear. One possibility is
