Why the Brain and Breath Part Ways During Heavy Slumber

New research reveals that during the deepest non-REM sleep, the brain’s neural rhythms become independent of breathing, a discovery that could unlock new treatments for Parkinson’s.

Less Deep Sleep Linked to Brain Shrinkage, Alzheimer’s Risk

New research shows that reduced time in slow wave and REM sleep is associated with smaller brain volumes in regions vulnerable to Alzheimer’s disease. Using sleep studies and brain imaging data from 270 participants, researchers found that poor sleep architecture was linked to brain atrophy over time—particularly in the inferior parietal region, an area affected early in Alzheimer’s.

Deep Sleep Drives Brain’s Waste Clearance, Aiding Cognitive Health

Deep sleep may clear the brain of toxic waste via a process driven by norepinephrine, a molecule that creates rhythmic blood vessel contractions. This "brainwashing" system, part of the glymphatic system, helps remove harmful proteins linked to neurological disorders.

Clues Into a Sleep Mystery

Using gene editing to disrupt a gene in the thalamus that codes for a protein that binds to GABA boosted the activity of delta waves and promoted deep sleep in mouse models.

Enhancing Deep Sleep

SleepLoop, a newly designed mobile system, can help promote deep sleep through auditory brain stimulation. The device tracks when a person enters slow-wave brain activity, triggering an auditory signal that helps synchronize neurons and enhance the slow waves.
