We live and navigate easily in a complex three-dimensional world. However, little is known how this three-dimensional space and our movements within it are represented in the human brain. Kim et al. scanned participants while they were performing a virtual navigation task. Behaviorally, subjects had similarly accurate memory for vertical and horizontal locations. For a direction judgment task, vertical tilt facilitated performance. A brain region called the right anterior hippocampus contains place information that is sensitive to both horizontal and vertical axes. Vertical directional information, however, is represented in the right posterior hippocampus in an area called the retrosplenial cortex.
