Delta wave activity disruption during sleep may be a useful metric to identify those at an increased risk for cardiovascular disease and cardiovascular mortality. An international team of researchers ...

Brain activity and breathing rhythms decouple during deep sleep, offering new insights into Parkinson's and anesthesia.

Scientists pinpoint the molecular epicenter of deep-sleep regulation. The findings, based on research in mice, identify a gene that makes a protein that regulates delta waves -- electrical signals ...

During sleep, the brain cleans itself, turning up the flow of cerebrospinal fluid through the gray matter parenchyma to wash away waste. What powers this flow? In the February 28 Nature online, ...
