People with insomnia have greater brain activity in regions associated with conscious awareness during NREM sleep, researchers report.
Researchers uncover how specific retinal cells respond to the artificial light generated by cell phone and tablets. The study reveals how retinal ganglion cells process ambient light and reset our circadian clocks, leading to sleep disruptions.
Researchers report they have identified the neurons responsible for why delaying bedtime can create chronic daytime sleepiness.
Neurologists at the University of Michigan reveal why some people get headaches when wearing their hair in ponytails. According to researchers, ponytail headaches are an example of allodynia, a normal stimuli interpreted as painful. A lack of sleep and a predisposition to migraine are some factors that may make the experience of pain worse.
