New sleep-promoting brain cells identified

On September 4, 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. …

Bad sleep increases Alzheimer's-related brain proteins

On July 12, 2017, Posted by , In Buzz, By ,,,, , With No Comments

Researchers from the United States and the Netherlands have shown that bouts of bad sleep can significantly increase the amount of tau and amyloid beta in the brain, which are linked to a higher risk of Alzheimer’s disease. A study of healthy, middle-aged adults has found that poor sleep can…

How do we override sleepiness? Brain region identified

Research presented at the latest Canadian Neuroscience Meeting connects fascinating insights into the science of dreams with the risk of developing neurological disorders. Scientists examine what goes on inside our brains when we dream and find surprising connections with neurodegenerative disorders. Research presented at the 2017 annual gathering…

A specific brain activity pattern for dreaming

On April 12, 2017, Posted by , In Buzz, By ,,,, , With No Comments

A specific pattern of activity changes within a particular brain region can indicate when a person experiences a dream during both rapid eye movement (REM) sleep and non-REM (NREM) sleep, reports a paper published online in Nature Neuroscience. The study challenges the current understanding of the pattern of brain…

Sleep apnea in children may stunt brain development

On March 18, 2017, Posted by , In Buzz, By ,,,,, , With No Comments

Sleep apnea, a common condition in which breathing briefly stops during the night, may reduce the amount of gray matter in a child’s brain, finds a recent study. Although further research is needed, the results are worrying. Sleep apnea’s effect on the developing brain is currently little understood. …

Visual evidence shows brain 'resetting' during sleep

On February 5, 2017, Posted by , In Buzz, By ,,,,,, , With No Comments

Throughout the day, the human brain absorbs a torrent of knowledge, processes the information, and learns, before “switching off” over night. New research explains this process in action. Microscopic images of synapses – the junction between two nerve cells – have been shown to expand with daytime stimulation and…

Experts have found that in order to maintain a healthy brain and stay mentally sharp, we must make it a priority to get the required amount of sleep in later life. What happens to our sleep as we age The new report into sleep in…

Recovery from brain injury and better sleep go hand in hand

On December 23, 2016, Posted by , In Buzz, By ,,,,,, , With No Comments

After a traumatic brain injury (TBI), people also experience major sleep problems, including changes in their sleep-wake cycle. A new study shows that recovering from these two conditions occurs in parallel. The study is published in Neurology®, the medical journal of the American Academy of Neurology. “These…
