Slow synaptic inhibition in nucleus HVc of the adult zebra finch.
Nervous systems process information over a broad range of time scales and thus need corresponding cellular mechanisms spanning that range. In the avian song system, long integration times are likely necessary to process auditory feedback of the bird's own vocalizations. For example, in nucleus HVc, a center that contains both auditory and premotor neurons and that is thought to act as a gateway...
متن کاملThe electrophysiological properties of HVC-RA synaptic transmission in the adult zebra finch in vivo.
The synaptic connection from high vocal center (HVC) to robust nucleus of the arcopallium (RA) is a pivotal part of vocal motor pathway in songbirds. Electrophysiological properties of HVC-RA synaptic transmission in adult male zebra finch (Taeniopygia guttata) in vivo was investigated by using field potential recording method. Following electrical stimulation of HVC, the evoked field potential...
متن کاملMultiple cell types distinguished by physiological, pharmacological, and anatomic properties in nucleus HVc of the adult zebra finch.
Nucleus HVc of the songbird is a distinct forebrain region that is essential for song production and shows selective responses to complex auditory stimuli. Two neuronal populations within HVc give rise to its efferent projections. One projection, to the robust nucleus of the archistriatum (RA), serves as the primary motor pathway for song production, and can also carry auditory information to R...
متن کاملGlobal synchronous response to autogenous song in zebra finch HVc.
1. The spatial distribution of neuronal responses to autogenous song (AS) was investigated in the HVc of urethan-anesthetized adult male zebra finches (Taeniopygia guttata). In seven birds, penetrations covered the entire mediolateral, rostrocaudal, or dorsoventral extents of HVc. In an eighth, control birth penetrations were made near to but outside of HVc. Reconstruction of recording sites fr...
متن کاملLearning-Related Neuronal Activation in the Zebra Finch Song System Nucleus HVC in Response to the Bird’s Own Song
Like many other songbird species, male zebra finches learn their song from a tutor early in life. Song learning in birds has strong parallels with speech acquisition in human infants at both the behavioral and neural levels. Forebrain nuclei in the 'song system' are important for the sensorimotor acquisition and production of song, while caudomedial pallial brain regions outside the song system...
