Chinese researchers from Peking University found the suprachiasmatic nucleus encodes time.

Chinese researchers from Peking University discovered that the suprachiasmatic nucleus (SCN), a mammal's brain region known as the central circadian pacemaker, encodes time using a group decision-making mechanism. Using a high-speed dual-view two-photon microscope, the team imaged calcium ion signals from up to 9,000 neurons to predict hourly time with 99% accuracy at a cohort size of 900, providing new insights into human biological clock systems.
