When something exciting or threatening happens, it can change how we move. But how do emotional signals in the brain actually reach the parts that control movement? The well-known route for voluntary ...

The brain may use dopamine to expand time between distinct events, enabling us to remember unique episodes.

MDRS is a professional society dedicated to the study of memory. Members engage in basic and clinical research into how memory works and why it fails.

Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans...

This study examined how agentic decisions in the absence of explicit rewards influence memory organization. Participants studied lists of items to assign as gifts to two characters-either choosing freely (Choice group) or following instructions (Fixed group). During free recall, participants in the …

Adaptive behavior requires integrating information from multiple sources. These sources can originate from distinct channels, such as internally maintained latent cognitive representations or external...

Episodic memory allows us to remember when an event occurred by situating it within a coherent temporal context. Pavlovian fear conditioning, a widely…

Inspired by recent discoveries of neural populations that track time for specific moments (time cells) and elapsed durations (temporal context and periodic time cells), this review, based on a minisym...

Does neural variability reflect random noise or a feature that benefits adaptive behavior? Using intracranial recordings in humans, Terlau et al. demonstrate that neural variability results from the r...

This study shows that hippocampal and entorhinal connectivity patterns drift over time in humans, providing a spontaneous neural signature of elapsed time that follows functional gradients and reveals network-specific contributions to temporal coding.

Our experience of the world is a continuous stream of events that must be segmented and organized at multiple timescales. The neural mechanisms underlying this process remain unknown. In this work, we...
