In recent years, the field has reached an impasse between models suggesting that the
hippocampus is fundamentally involved in spatial processing and models suggesting that …

Navigation is an inherently dynamic and multimodal process, making isolation of the unique
cognitive components underlying it challenging. The assumptions of much of the literature …

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 …

Electroencephalography (EEG) frequencies have been linked to specific functions as an
“electrophysiological signature” of a function. A combination of oscillatory rhythms has also …

Resting state functional MRI (R-fMRI) studies have shown that slow (< 0.1 Hz), intrinsic
fluctuations of the blood oxygen level dependent (BOLD) signal are temporally correlated …

Active navigation seems to yield better spatial knowledge than passive navigation, but it is
unclear how active decision-making influences learning and memory. Here, we examined …

During normal aging resting-state brain activity changes and working memory performance
declines as compared to young adulthood. Interestingly, previous studies reported that …

Investigations using noninvasive functional magnetic resonance imaging (fMRI) have
provided significant insights into the unique functional organization and profound …

Humans possess the remarkable ability to search their memory, allowing specific past
episodes to be re-experienced spontaneously. Here, we administered a free recall test to …

Low-frequency (delta/theta band) hippocampal neural oscillations play prominent roles in
computational models of spatial navigation, but their exact function remains unknown. Some …
