Abstract: Just a song at sunrise Behavioural studies show that sleep plays a role in learning, and birdsong is a well established model system for the study of learning. It has been proposed that forebrain premotor neuron activity in sleeping adult zebra finches reflects daytime singing episodes. Now Sylvan Shank and Daniel Margoliash demonstrate a surprising role for sleep in establishing the organization of the songbird's brain at the time the bird first starts to learn to sing. In juvenile zebra finches yet to master their song, exposure to an adult 'tutor' song produced profound changes in the premotor neuronal activity during the subsequent sleep session. These changes in night-time activity are echoed in tutor-song-induced changes in singing the next day.
