Astrocytes could be as important as neurons when it comes to regulating sleep. Read More
Obstructive sleep apnea alters the gut microbiome in mice. Transplanting gut bacteria from mice with OSA to those without the disorder caused sleep disruptions. Read More
Parkinson's disease can be divided into two variants that start in different places in the body. For some, the neurodegenerative disease starts in the intestines and spreads to the brain. In others, the disease begins in the brain and spreads to the intestines and other organs. Read More
When a child reaches the age of two-and-a-half, the primary purpose of sleep changes from brain-building to brain maintenance and repair, a role it maintains for the rest of our lives. Read More
HIRREM, a closed-loop acoustic stimulation neurotechnology, reduced insomnia symptoms, and improved autonomic nervous system function. Read More
Cortical representations for the sounds and meanings of new words learned form within an hour or two following exposure. Read More
Shorter sleep duration causes people to react more emotionally to stressful events and find less joy in positive events the next day. Following a good night of rest, people's reaction to positive and negative events improves dramatically. Read More
Researchers have identified a neural circuit responsible for inducing insomnia associated with stress. The same neural circuit also induces changes in the immune system. Read More
Study reveals how sleep deprivation can greatly affect soldiers on the battlefield. Read More
Current sleep patterns could help determine your risk of developing Alzheimer's disease as you age. People who experience more fragmented sleep and less non-REM slow-wave sleep are more likely to have increased levels of amyloid-beta. Read More
During wakeful periods, the glymphatic system diverts cerebrospinal fluid to lymph nodes in the neck. The CSF may act as a "fluid clock" that helps initiate the body's infection-fighting capabilities during the day. Astrocytes in the suprachiasmatic nucleus may serve to control CSF through the central nervous system. Communication between astrocytes in different brain regions may optimize the glymphatic system's function as we sleep. Read More
Digital sleep therapy could be an effective method to treat insomnia and reduce the use of sleeping pills. Read More
