image: Neurons in the suprachasmatic nuclei (SCNs) control the timing of daily activities in mammals. Green EGFP labeled neurons within these nuclei, which express the key clock gene, per1, send a unique pattern of electrical firing indicating the time of day. These unique bioelectrical behaviours, missed by electrophysiologists for over 30 years, were predicted by mathematical modeling. This image relates to an article that appeared in the October 9 issue of Science, published by AAAS. The study, by Dr. M.D.C. Belle at University of Manchester in Manchester, UK, and colleagues, was titled, "Daily Electrical Silencing in the Mammalian Circadian Clock." view more
