The first time a breathing rhythm in the human hippocampus found during sleep Breathing is the metronome that coordinates sleep oscillations Findings are important for people with disordered breathing ...

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 ...

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.

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 new study reveals that while we sleep, our brains quietly sort through the day’s experiences, keeping what we intend to remember and letting emotion-driven moments drift away. Study: Top-down ...
