          Sleep Brain Waves Linked to Consciousness in Coma

          A new study finds that sleep spindles—bursts of brain activity during sleep—may predict recovery in unresponsive patients with recent brain injuries. Researchers analyzed EEG recordings of 226 comatose patients and found that those with sleep spindles were significantly more likely to regain consciousness and functional independence.

          Short-Term Rhythms Shape Sleep Spindles and Brain Health

          Sleep spindles—brief bursts of brain activity crucial for memory and sleep stability—are guided primarily by short-term timing patterns lasting less than 15 seconds. Researchers found these patterns are highly individualized, consistent across nights, and change with age, outweighing the influence of other factors like brain rhythms or sleep depth.

          How Deep Sleep Brain Waves Can Impact Blood Sugar Levels

          Deep-sleep brain waves could be a significant factor in regulating blood sugar. The research shows that a combination of sleep spindles and slow waves can predict an increase in insulin sensitivity, subsequently lowering glucose levels.

          Researchers Find Human Infant Brains and Bodies Are Active During New Sleep Stage

          Infants produce sleep spindles every 10 second, whether in REM or non-REM sleep. Sleep spindles and twitching are synchronized, allowing for twitch reactions to occur during non-REM sleep in infants.

          How the Brain Strengthens Memories During Sleep

          The reactivation of learned material during slow oscillation/sleep spindle complexes, and the precision of SO-spindle coupling predicts how strong a memory will be reactivated in the brain.

          NMDA receptors may link psychosis and sleep deficits

          NMDA receptor hypofunction is involved in the reduction of sleep spindles and delta oscillations, which appear in the brain during deep natural sleep. Findings confirm the role NMDA receptors play in sleep disorders that accompany psychotic states.

          Sleep history predicts late-life Alzheimer’s pathology

          Your sleep history during middle age may predict Alzheimer's pathology later in life. A decrease in sleep quality between 50 and 70 years of age is associated with higher levels of tau and amyloid beta in the brain. Changes in brain activity and quality of sleep could be a biomarker for Alzheimer's disease.
