Tsukuba, Japan—Researchers at the Tsukuba University in Japan report that memories acquired while awake are stored in a more permanent form (called memory consolidation) during the REM stage of sleep, ...

A context-driven memory model simulates a wide range of characteristics of waking and sleeping hippocampal replay, providing a new account of how and why replay occurs.

A gene that plays a key role in regulating how bodies change across the 24-hour day also influences memory formation, allowing mice to consolidate memories better during the day than at night.

Sleep plays a crucial role in memory consolidation. It is during deep sleep that the brain organises and stores information ...

These distinct tests enabled the scientists to observe specific hippocampal activity during learning and then memory replay and consolidation in sleep. Because of the way our pupils change in response ...

The researchers found that measures of obstructive sleep apnea-related hypoxemia significantly predicted global white matter hyperintensity volume of the brain, which was driven by hypoxemia severity ...

People spend about one third of their lives sleeping. Fingers glide across a phone screen or thoughts drift toward the day ahead, but soon, eyelids grow heavy, and sleep begins to take hold. During ...
