Distinct neurons drive mice's social sounds and squeaks

Mice use almost completely distinct sets of neurons for their two different types of vocalizations—the squeaks they produce when in distress or fighting and the whistle-like ultrasonic vocalizations they use when communicating socially, Cornell neuroscientists have found. The discovery is a step toward understanding how the brain is organized to control vocalization in mammals, including humans.
