The part of our sleep cycle involving Rapid Eye Movement (REM), otherwise known as paradoxical sleep, is a crucial phase of sleep identified in mammals and birds involving the random … Continue Reading Researchers identify neurons responsible for rapid eye movements/REM during sleep.
Insomnia is a sleep disorder where people have difficulty falling asleep or staying asleep for a healthy amount of time, with over 770 million people suffering from sleeplessness worldwide. Currently, … Continue Reading 1.3 million patient genetics study identifies brain cells involved in insomnia.
Sleep deprivation is the condition of not having enough sleep; it can be either chronic or acute. A chronic sleep-restricted state can cause fatigue, daytime sleepiness, clumsiness, and weight loss … Continue Reading Short-term sleep deprivation shown to affect heart function.
Sleep apnea’s variable oxygen levels cause damage that is detectable at the tissue level. Although many other confounding factors exist, sleep apnea is shown to be an independent factor associated … Continue Reading Study shows that sleep apnea can help enable the spread of lung cancer cells.
It is known that salt is important for cognitive function. Although some studies do link a lower level of sodium with a reduction in blood pressure and heart disease, studies … Continue Reading Study shows that levels of salts in the brain controls whether a person is alseep or awake.
All animals need to sleep for varying durations and in humans, sleep duration changes over their lifetime, gradually reducing from birth through to old age. The mammalian body appears to … Continue Reading Researchers identify neurogenetics responsible for sleep duration.
One in 15 adults has moderate to severe obstructive sleep apnea (OSA), a disorder in which a person’s breathing is frequently interrupted during sleep, as many as 30 times per … Continue Reading Neuroimaging confirms that sleep apnea takes a toll on brain function.
It is known that a 24-hour circadian rhythm controls nearly all brain and body processes, such as the sleep/wake cycle, metabolism, alertness and cognition. These daily activity patterns are regulated … Continue Reading Researchers map the circadian neurogenetics involved in brain aging.
Caring for patients with heart failure costs the United States $40 billion a year. Despite the condition’s enormous impact, few new treatments have been developed, and those that exist produce … Continue Reading Human study identifies sleep gene linked to heart failure.
Sleep seems simple enough, a state of rest and restoration that almost every vertebrate creature must enter regularly in order to survive. However, the brain responds differently to stimuli when … Continue Reading Researchers identify the calcium channel in the brain essential for deep sleep.
Using a simple device for eight hours a night to treat sleep apnea can help people with prediabetes improve their blood sugar levels and may reduce the risk of progressing … Continue Reading Study shows that effective sleep apnea treatment lowers diabetes risk.
Autism spectrum disorder (ASD) can produce strikingly different clinical outcomes in young children, with some having strong conversation abilities and others not talking at all. Now a study from researchers … Continue Reading Researchers identify biomarker for language outcomes in infants with autism spectrum disorder.
A team of researchers form the UT Southwestern Medical Center and University of Tsukuba have identified key cells within the brain that are critical for determining circadian rhythms, the 24-hour … Continue Reading Researchers identify elusive cell type in the brain that control circadian rhythms.
Stating that sleep is an essential biological process seems as obvious as saying that the sun rises every morning. Yet, researchers’ understanding of the molecular mechanisms underlying the effects of … Continue Reading Lipidomics study identifies common biomarkers of sleep debt in humans and rats.
Researchers at Massachusetts General Hospital (MGH) and Massachusetts Institute of Technology (MIT) have added another piece to the complex puzzle of how the brain controls one of the most essential … Continue Reading Optogenetics study identifies neurons important for induction of natural REM sleep.
