Many studies have linked poor sleep with a decline in brain functioning. A research team focused on the glial-lymphatic (glymphatic) system, a fluid transport pathway that plays a vital role in clearing waste from the brain.
Researchers have discovered how perceptual memories linked to positive emotions are strengthened during sleep—with a surprising sleep stage playing a key role.
The device is designed to improve insomnia by delivering a small electrical pulse to the head for 30 minutes before bed.
Sleep-deprived participants had difficulty activating the part of the brain responsible for controlling memories, making it harder for them to manage unwanted memories over time.

Sleep apnea may lead to increased brain growth in the hippocampus, which could have implications for memory and cognitive function.

Brain waves that allow memory consolidation are synchronized by breathing. The findings are important for people with sleep-disordered breathing.

Sleep Cycle has partnered with researchers from the University of Cambridge and University College London to explore how combining its sleep data with navigational data can aid in the early detection of Alzheimer’s disease.

It has been known for nearly 20 years that slow, synchronous electrical waves in the brain during deep sleep support the formation of memories. Why that is was previously unknown.

The cognitive benefits of moderate-to-vigorous exercise can last up to 24 hours, especially when paired with good sleep.

Place cells are well known to encode individual locations, but new experiments and analysis indicate that stitching together a “cognitive map” of a whole environment requires a broader ensemble of cells, aided by sleep, to build a richer network over.

A new study reveals that sleep helps the brain store words and grammar, making it easier to learn and remember.

Researchers found that NREM sleep enhances brain function and discovered a way to replicate its benefits artificially without requiring sleep.

The locus coeruleus, a brainstem region, has so far been known as the major regulator of the ability to react to challenging situations during wakefulness, not sleep.
