Sleeplessness slows down our brains, which affects how we perceive stimuli. This may put us in dangerous situations. New research confirms that lack of proper sleep has a severe impact on how the brain functions, with potentially dangerous consequences arising in daily life. Lately, many studies have focused on how sleep affects…

New sleep-promoting brain cells identified

On September 27, 2017, Posted by , In Buzz, By ,,, , With No Comments

Neurons that express the so-called Lhx6 gene may promote sleep by “switching off” other neurons. New research in mice identifies a range of neurons that may be involved in promoting sleep. The findings may soon change therapeutic practices for treating sleep disorders. Insomnia affects around 60 million people in the…

Sleep biology discovery could lead to new insomnia treatments that don't target the brain

UCLA scientists report the first evidence that a gene outside the brain controls the ability to rebound from sleep deprivation – a surprising discovery that could eventually lead to greatly improved treatments for insomnia and other sleep disorders that do not involve getting a drug into the brain. …
