Researchers developed a novel “closed-loop” system that delivered electrical pulses in a brain region to synchronize brain activity recorded from another region in the brain to improve memory. Among ...

Research suggests that both REM (rapid eye movement) and NREM (non-rapid eye movement) stages in the sleep cycle are ...

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 ...

During sleep, the brain strengthens memories it expects to use in the future. Now, scientists say they've found a way to enhance this process. This research might someday help people with memory loss.

Neuroscientists have established in recent decades the idea that some of each day's experiences are converted by the brain into permanent memories during sleep the same night. Now, a new study ...

Some forms of exercise are worse than others for sleep, too. For instance, high-intensity exercise—like HIIT, sprint ...

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, ...

We’re aware that a good night’s sleep helps to restore energy, but a new study in rats and mice, carried by scientists at Cornell University, has found that sleep also resets another vital function, ...
