Scientists Map the Wiring of the Biological Clock

Researchers report the discovery of a crucial part of the biological clock: the wiring that sets its accuracy to within a few minutes out of the 1440 minutes per day. The wiring uses GABA to connect the individual cells of the biological clock in a fast network which changes strength with the time of day.
