Humans and animals use mental representations of the spatial structure of the world to
navigate. The classical view is that these representations take the form of Euclidean …

The mammalian hippocampal formation contains several distinct populations of neurons
involved in representing self-position and orientation. These neurons, which include place …

Memory and planning rely on learning the structure of relationships among experiences.
Compact representations of these structures guide flexible behavior in humans and animals …

We would like to thank our families for their patience and understanding as we took time off
to work on this book. We dedicate this book to Dr. Howard Eichenbaum, a leader in the field …

Efficient navigation from one place to another is facilitated by the ability to use spatial
boundaries to segment routes into their component parts. Similarly, memory for individual …

Licensed London taxi drivers have been found to show changes in the gray matter density of
their hippocampus over the course of training and decades of navigation in London (UK) …

Recent research indicates the hippocampus may code the distance to the goal during
navigation of newly learned environments. It is unclear however, whether this also pertains …

Remembering event sequences is central to episodic memory and presumably supported by
the hippocampal-entorhinal region. We previously demonstrated that the hippocampus …

Environmental boundaries anchor cognitive maps that support memory. However,
trapezoidal boundary geometry distorts the regular firing patterns of entorhinal grid cells …

Judging how far away something is and how long it takes to get there is critical to memory
and navigation. Yet, the neural codes for spatial and temporal information remain unclear …
