The Skin Keeps Time Independent Of The Brain

A type of opsin known as neuropsin is expressed in the hair follicles of mice and synchronize the skin’s circadian clock to the light-dark cycle, independent of the eyes or brain, University of Washington researchers report. “This is the first functional demonstration of opsin photoreceptors outside the eye directly controlling circadian rhythms in a mammal,” […]

How Bright Flashes Of Light Get Teens More Sleep

Teens got 43 more minutes of sleep a night after a four-week intervention that reset their body clocks and helped them go to bed earlier, Stanford researchers report[1]. The treatment had two components: brief, early morning flashes of bright, broad-spectrum white light to reset the teens’ circadian clocks, and cognitive behavioral therapy that motivated them […]

Gene Expression Rhythms Are Disrupted In Schizophrenia-Affected Brains

Rhythms in gene expression in the brain are highly disrupted in people with schizophrenia, according to a new University of Pittsburgh-led study. The findings also suggest that researchers studying schizophrenia-linked genes in the brain could have missed important clues that would help understand the disease. “Our study shows for the first time that there are […]
