Memory routinely transforms continuous experience into discrete episodes that support flexible retrieval. We propose that these structured representations are established via rapid neural reactivation...

How past experiences are reconstructed from memory remains unclear. Here the authors used intracranial EEG to show that hippocampal ripples reshape the geometry of cortical representations, supporting...

Hippocampal ripples are considered a key mechanism of sleep-dependent memory consolidation. In humans, however, their direct investigation has relied on invasive recordings from patients with epilepsy...

Gaze behavior and brain activity are tightly coupled during perception and mental imagery. Whether this coupling extends to eyes-closed states remains largely unknown, primarily because measuring eye ...

Slack is a new way to communicate with your team. It’s faster, better organized, and more secure than email.

Noninvasive methods are making it possible to study neural replay in humans. Although focused on alignment with rodent findings, human research often …

Using direct recordings from the human brain, Frank et al. show that hippocampal ripples increase ahead of unpredictable events and tune the visual cortex to respond faster and more strongly to surpri...

Hippocampal ripples are transient, high-frequency oscillations linked to memory replay and consolidation. Ripples are well-characterized in rodents to occur during periods of behavioral inactivity (i....

A combined MEG + fMRI benchmark dataset with known neural sequences to validate replay detection methods (TDLM and SODA).

Studies in rodents and humans using invasive electrophysiology have established that neural replay is a ubiquitous phenomenon in the brain that is associated with a wide range of cognitive functions, ...

Using simultaneous EEG-fMRI, we identify two types of NREM slow waves with distinct thalamic profiles. Large, synchronized waves involve early thalamic activation and arousal markers, whereas smaller ...

Nature Human Behaviour, Published online: 27 May 2026; doi:10.1038/s41562-026-02446-zChowdhury et al. report the discovery of a 19–45-Hz thalamic oscillation that is present during human wakefulness and REM sleep, but not NREM sleep.

Context-dependent behavior selects actions according to task demands. Using direct brain recordings in humans, Binish et al. uncover how coordinated population activity efficiently channels informatio...

By definition, episodic memory is a conscious phenomenon. Memory traces reactivated by the hippocampus and reinstated in the sensory cortices need to enter conscious awareness for them to be re-experi...

Blumberg et al. present video evidence of twitching during adult sleep in a diverse sample of animals. Adult twitching appears to selectively involve appendages used for active sensing, mirroring thei...

Join our 4-day summer school on memory consolidation, neural replay, and sleep. May 31–June 3, 2026 in Heidelberg. For Master, PhD students & postdocs.

Testing items in working memory improves long-term memory, especially for deprioritized items. This benefit shows when WM retrieval requires continuous recall, suggesting self-generated reports streng...

How aperiodic 1/f noise drives ripple activity in human brain and impacts on ripple detections is not fully understood. Here authors show that ripple detections should be driven by the 1/f noise, whic...
