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…
