In both animals and humans, vocal signals used for communication contain a wide array of different sounds that are determined by the vibrational frequencies of vocal cords. Knowing how the brain sorts out these different frequencies -- which are called frequency-modulated sweeps—is believed to be essential to understanding many hearing-related behaviors, like speech.
