Implication

Neurophysiological study demonstrates motor inhibition of auditory responses in the songbird HVc nucleus during singing, indicating central gating of sensory feedback during vocal production.

Key Points

Investigate the direct electrophysiological role of the HVc nucleus during singing and determine how motor and auditory activities interact within this song control center.
Recorded extracellular neuronal activity from nucleus HVc in awake, freely behaving songbirds during spontaneous singing and auditory playback of the bird's own song.
Evaluated song-correlated neural firing patterns in both intact and deafened songbirds.
Administered auditory stimuli during active singing and tracked the post-vocalization persistence of sensory responsiveness.
HVc neurons displayed distinct temporal firing patterns during singing that persisted identically in deafened birds.
Production-correlated neural activity patterns in normal birds were distinguishable from sensory responses elicited by auditory playback of the same song syllables.
Active singing exerted motor inhibition over auditory responses in HVc, with sensory responsiveness recovering slowly over several seconds following song termination.
