Control of Vocal and Respiratory Patterns in Birdsong: Dissection of Forebrain and Brainstem Mechanisms Using Temperature

Learned motor behaviors require descending forebrain control to be coordinated with midbrain and brainstem motor systems. In songbirds, such as the zebra finch, regular breathing is controlled by brainstem centers, but when the adult songbird begins to sing, its breathing becomes tightly coordinated with forebrain-controlled vocalizations. The periods of silence (gaps) between song syllables ar...

Birdsong: models and mechanisms.

Recent studies have provided important information concerning the neural signals that subserve vocal learning in songbirds: advanced signal processing techniques are beginning to clarify the behavioral trajectories followed by developing birds; single-unit physiology in behaving animals is providing important clues about sensory and motor representations during learning; in vitro whole-cell rec...

Brains and birdsong

Birdsong and singing behavior.

Birdsong provides neuroscientists with a uniquely powerful model for studying imitative vocal learning in a system where the brain structures responsible for song learning and production are well known. The 4,500+ species of songbirds provide a remarkable diversity of songs with a variety of tonal, structural, and learning characteristics, but most studies of the neural bases of learning have c...
