Discrete telencephalic nuclei HVc (hyperstriatum ventrale, pars caudale) and RA (nucleus robustus archistriatalis) have been implicated by lesion studies in the control of vocalization in songbirds. We demonstrate directly the role of HVc in vocalization by presenting neuronal recordings taken from HVc of singing birds. Intracellular recordings from anesthetized birds have shown that many neurons in HVc respond to auditory stimuli. We confirm this result in the extracellular recordings from…

A Synaptic Basis for Auditory–Vocal Integration in the Songbird
It is found that CM neurons are active in response to song playback and during singing, indicating their potential importance to song perception and processing of auditory feedback.
Song-selective auditory input to a forebrain vocal control nucleus in the zebra finch.
The results show that an input other than that from LMAN must be primarily responsible for auditory responses in RA, and that the direct projection from HVC is the most likely pathway by which song selective auditory information arrives in RA.
Different Subthreshold Mechanisms Underlie Song Selectivity in Identified HVc Neurons of the Zebra Finch

In vivo intracellular recordings from morphologically and electrophysiologically identified HVc neurons revealed that both relay cell types fire song-selectively, however, their firing arises via markedly different subthreshold processes, and only X-projecting neurons appear to be sites for auditory refinement.
Thalamic Gating of Auditory Responses in Telencephalic Song Control Nuclei
The results suggest that Uva can gate auditory responses in HVC through a mechanism that involves inhibition local to HVC as well as withdrawal of auditory-evoked excitatory drive from NIf, which could play an important role in state-dependent gating of auditory activity in telencephalic sensorimotor structures important to learned vocal control.

It is demonstrated that the entire population of auditory neurons in the HVc is selective for autogenous song, which can contribute to the ability to distinguish the fine differences among conspecific songs.
A bird's eye view: top down intracellular analyses of auditory selectivity for learned vocalizations
Evidence for an auditory-perceptual role of the song system, the anatomical pathways by which auditory information enters the songSystem, the synaptic events underlying highly selective action potential responses to learned song, and the possible roles such activity could play in song learning and maintenance are discussed.

Young songbirds memorize a tutor song and use the memory trace as a template to shape their own song by auditory feedback, and it is not known whether the gating is involved in switching between the premotor and auditory function of neurons in the song control system.

It is proposed that HVc auditory neurons may contribute to a bird's ability to discriminate among conspecific songs by acting as an “autogenous reference” during perception of those songs.
Functional organization of forebrain pathways for song production and perception.
It is suggested that a major role of the anterior forebrain pathway is to resolve the timing mismatch between motor program readout and sensory feedback, thereby facilitating motor programming during birdsong learning.
