The roles of the hippocampus and prefrontal cortex (PFC) in memory processing—
individually or in concert—are a major topic of interest in memory research. These brain …

Attention is the gate through which sensory information enters our conscious experiences.
Oftentimes, patients with major depressive disorder (MDD) complain of concentration …

Spatial working memory, the caching of behaviourally relevant spatial cues on a timescale of
seconds, is a fundamental constituent of cognition. Although the prefrontal cortex and …

When rats come to a decision point, they sometimes pause and look back and forth as if
deliberating over the choice; at other times, they proceed as if they have already made their …

Some have claimed that the medial prefrontal cortex (mPFC) mediates decision making.
Others suggest mPFC is selectively involved in the retrieval of remote long-term memory. Yet …

Search is a ubiquitous property of life. Although diverse domains have worked on search
problems largely in isolation, recent trends across disciplines indicate that the formal …

The hippocampal formation (HPC) and medial prefrontal cortex (mPFC) have well-
established roles in memory encoding and retrieval. However, the mechanisms underlying …

The theta rhythm is one of the largest and most sinusoidal activity patterns in the brain. Here
I survey progress in the field of theta rhythms research. I present arguments supporting the …

The nucleus reuniens of the thalamus (RE) is a key component of an extensive network of
hippocampal and cortical structures and is a fundamental substrate for cognition. A common …

Hippocampal information processing is discretized by oscillations, and the ensemble activity
of place cells is organized into temporal sequences bounded by theta cycles. Theta …
