complementary sensors39. These sensors typically allow for the measurement of (1) brain activity through electroencephalogram (EEG), (2) airflow, (3) breathing effort and rate, (4) blood oxygen levels, (5) body position, (6) eye movement, (7) electrical...

In this study, we investigated the cause of snoring sound鈥檚 variation within ...
Sleep apneaoccurs when the upper airway becomes completely or partially blocked, interrupting regular breathing for short periods of time -- which then wakes you up. It can cause severe daytime sleepiness. If left untreated, severesleep apneamay be associated with high blood pressure and the risk ...

When cells experience low oxygen levels (hypoxia) as in congestive heart failure, it triggers the activation of a protein called HIF-1α. This protein is involved in various cellular processes, such as controlling cell death, regulating blood vessel constriction, managing energy usage, and promotin...
It’s basically naptime for the nerve cells in yourbrainas you dip into non-REM sleep. They do send out a few messages, but nothing much. But like so many other bodily functions,brainactivity goes up during REM sleep, sometimes even more than during the day. Blood flow to thebrainand ...
relatively high levels of oxygenconsumptionby thebrain, increasedcerebralblood flow, and higher brain temperature. This brain activation during REM sleep has been shown to be localized in several areas of thebrainstemand thalamus as well as in neural structures usually involved in the regulation ofemot...

A combination of blood-oxygen level dependent imaging (BOLD) and EEG, was the first study to demonstrate a clear connection between slow wave sleep, hemodynamic oscillations and CSF clearance [40]. Interestingly, during sleep, the CSF flow dynamics were anticorrelated to haemodynamic oscillations, ...
High blood pressure or heart problems.Sudden drops in blood oxygen levels while you sleep can raise your blood pressure and put stress on your cardiovascular system. Obstructive sleep apnea could also put you at higher risk for recurrent heart attacks, strokes, or abnormal heartbeats. ...
