Abstract

Birdsong is a model system for understanding how motor and sensory information interact to coordinate behavior. Neurons in one potential site of sensorimotor integration, the forebrain nucleus HVc, have premotor activity during singing and auditory activity during playback of the bird's own song. It is not known whether the high degree of selectivity for learned features of song observed during playback arises in HVc or also in structures afferent to HVc. We recorded in anesthetized adult zebra finches from two structures afferent to HVc: either the nucleus interfacialis (Nlf) or the L1 subdivision of the field L complex, and simultaneously from a second electrode in HVc. Correlations in the bursting pattern of ongoing activity of HVc and Nlf recordings were observed; these helped to localize the first electrode to Nlf recording sites. Most Nlf neurons exhibited song-selective responses, but as a population, they were less selective than were HVc neurons. MostL1 neurons were not song-selective. Nlf neurons have also been reported tohave premotor activity during singing; thus, Nlf is another potential siteof auditory-motor interactions in the song system. Evidence gathered to date suggests that those brain areas in the passerine forebrain that are recruited during song production also display the most selective learned auditory responses.
