A mouse virtual reality system is presented which allows normal spatial behavior and place, grid and head-direction cell firing patterns in 2-D arenas, and is compatible with electrophysiology and multi-photon imaging.
When mice use vision to choose their trajectories, a large fraction of parietal cortex activity can be precisely predicted from navigational attributes such as spatial position and heading.

Functional magnetic resonance imaging performed while people imagined directions from stationary viewpoints supports theories suggesting that spatially tuned cells such as grid cells underlie mental simulation for future thinking.

Extensive field studies in poison frogs reveal that sex and species differences in parental behavior drive differences in space use patterns but not navigational performance and highlight the interplay between androgen levels and poison frog spatial behavior.

The spatial and temporal patterns of eye movements exhibited by humans in virtual reality reveal how they plan paths when navigating in complex, naturalistic environments.
The BB model explains spatial cognition in terms of interactions between specific neuronal populations, providing a common computational framework for the human neuropsychological and in vivo animal electrophysiological literatures.
Parahippocampal neurons increase their activity rates following navigational errors, and the error signal magnitude is related with overall task performance.
