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.
A study from Rochester University researchers adds to growing evidence that school start times can have an impact on adolescent mental health.They reveal teens who start school before 8:30 am are at an increased risk of developing depression and anxiety due to compromised sleep quality.
A simple eye test may be a useful tool in helping to diagnose ASD, a new study reports. Researchers measured eye movement in those on the autism spectrum and found they continually missed a specific target. The researchers suggest sensory motor control in the cerebellum that is usually responsible for eye control could be impaired in those with ASD.
A new study in Scientific Reports concludes human herpesvirus 6 may impair the brain's ability to repair itself in demylination diseases, such as multiple sclerosis. HHV-6 is the most common human herpes virus, with an estimated 80% of people being exposed to infection during childhood. Researchers found the virus produces a protein that can impair the ability of brain cells to repair damaged myelin.
Microglia play a critical role in reorganizing neural connections, fighting infections, and repairing damage to neurons while we sleep.
According to researchers, a small alcoholic drink each day may be beneficial for brain health. Using mice, researchers found low levels of alcohol consumption is associated with less brain inflammation and a more effective glymphatic system. This allows CSF to flow more efficiently through the brain and remove waste that can lead to neurodegenerative diseases.
Combining neuroimaging data with artificial intelligence technology, researchers have identified a complex network within the brain that comprehends the meaning of spoken sentences.
Study reinforces and explains the links between sleep deprivation and neurodegenerative diseases, researchers say.
