    In the present paper, we reviewed a large body of evidence, mainly from quantitative EEG studies of our laboratory, supporting the notion that sleep is a local and use-dependent process. Quantitative analyses of sleep EEG recorded from multiple cortical derivations clearly indicate that every...

    The article reports on research which shows that an internal clock hidden in skin cells could reveal if your body clock is not in sync with your lifestyle. The brain's circadian clock causes a gene called Bmal1 to be more active in peripheral cells during the daytime. Researchers used a virus to...
