The hypoglossal motor neurons that innervate the vocal organ (syrinx) of the male zebra finch show a selective, long-latency (50-millisecond) response to sound. This response is eliminated by lesions to forebrain song-control nuclei. Different song syllables elicit a response from different syringeal motor neurons. Conspecific vocalizations may therefore be perceived as members of a set of vocal gestures and thus distinct from other environmental sounds. This hypothesis is an avian parallel to… Expand
Song-selective auditory input to a forebrain vocal control nucleus in the zebra finch.
TLDR
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. Expand
Auditory–vocal mirroring in songbirds

  • 2014
TLDR
The auditory and motor-related properties of these cells are discussed, their potential role on song learning and communication in relation to classical studies of birdsong is considered, and the circuit and developmental mechanisms that may give rise to auditory–vocal mirroring in the songbird's brain are pointed to. Expand
Behavioral state modulation of auditory activity in a vocal motor system.
TLDR
Sleep induced complex patterns of bursts in ongoing activity and uncovered vigorous auditory responses of RA neurons, suggesting motor access to auditory feedback, which zebra finches require for song learning and maintenance, may be regulated through neuromodulation. Expand
Song learning in birds: the relation between perception and production.
TLDR
The vocal control system of oscine songbirds has some perplexing properties that are not predicted by common views of how vocal learning takes place and the relation between the direct pathway for the control of learned song and the recursive pathway necessary for song learning is not understood. Expand
Vocal learning in birds and humans.
TLDR
A review of some of the salient anatomical, developmental, and behavioral features of vocal learning, alongside parallels and differences between vocal learning in songbirds and humans are reviewed. Expand
Song Selectivity in the Song System and in the Auditory Forebrain
TLDR
Three levels of selectivity found in the primary auditory forebrain areas, the secondary auditory fore brain areas, and the song system suggest a form of hierarchical sensory processing, the functional connectivity between these areas and the mechanisms generating the specific selectivity for songs that are behaviorally relevant or crucial in song learning and production have yet to be revealed. Expand
Altered Auditory BOLD Response to Conspecific Birdsong in Zebra Finches with Stuttered Syllables
TLDR
Auditory responses in two groups of zebra finches that differ in the type of song they sing after being tutored by birds producing stuttering-like syllable repetitions are examined to suggest a relationship between an altered response related to familiarity and/or saliency of song stimuli and the production of variant songs with stuttered syllables. Expand
Intrinsic and Extrinsic Contributions to Auditory Selectivity in a Song Nucleus Critical for Vocal Plasticity
TLDR
In vivo intracellular recordings from LMAN projection neurons, coupled with local circuit inactivation, reveal that much of LMAN′s song selectivity is supplied by its extrinsic inputs, but selective blockade of GABA receptors indicates that local inhibition is required for the expression ofsong selectivity.

Abstract: A hallmark of sensitive periods of development is an enhanced capacity for learning, such that experience exerts a profound effect on the brain resulting in the establishment of behaviorsExpand
Experimental test of the birdsong error-correction model.

  • 2004
TLDR
The results suggest that BOS tuning in LMAN is not used for error detection and constrain the nature of any error signal from LMAN to the motor system, and that a large portion of the input to this nucleus is from the motor control signals that generate the song rather than from auditory feedback.

Sexual dimorphism in vocal control areas of the songbird brain.
TLDR
In canaries and zebra finches, three vocal control areas in the brain are strikingly larger in males than in females, believed to be the first report of such gross sexual dimorphism in a vertebrate brain. Expand

TLDR
The auditory response properties of units in one of the telencephalic nuclei controlling song have recently been shown to respond to acoustic stimuli are investigated using a technique that permitted great flexibility in manipulating complex stimuli such as song. Expand

Forebrain lesions disrupt development but not maintenance of song in passerine birds.
TLDR
Lesions in the magnocellular nucleus of the anterior neostriatum of passerine birds disrupted song development in juvenile male zebra finches but did not affect maintenance of stable song patterns by adult birds. Expand
Coordinated activities of middle-ear and laryngeal muscles in echolocating bats.
TLDR
The middle-ear muscles and laryngeal muscles of the little brown bat (Myotis lucifugus) are highly developed and apparently activated in a coordinated manner not only by the nerve impulses from the vocalization center, but also by those from the auditory system. Expand
Central control of song in the canary, Serinus canarius
TLDR
Central nervous pathways controlling bird son in the canary are traced using a combination of behavioral and anatomical techniques and direct connections were found onto the cells of the motor nucleus innervating the syrinx, the organ of song production. Expand
Species song discrimination in choice experiments with territorial male swamp and song sparrows
TLDR
Syllable morphology influences the discrimination of conspecific song from song sparrow song in adult swamp sparrows, but temporal pattern does not; this result duplicates that found in studies of song learning of the young in this species. Expand
Connections of vocal control nuclei in the canary telencephalon
TLDR
Connections of two telencephalic vocal control nuclei, the hyperstriatum ventrale, pars caudale (HVc), and robust nucleus of the archistriatum (RA), were investigated in adult canaries, suggesting that HVc is composed of rostrocaudally organized clusters of cells, with little lateral communication between them.

The modifiability of the brown-headed female cowbird's response to male song is investigated, and data on song perception are contrasted with those previously obtained for male production and indicate different constraints onsong perception as opposed to song production. Expand

TLDR
Female song sparrows were sensitive to both syllable type and temporal, pattern, in contrast to male swamp sp Sparrows, which show no preference for swamp sparrow temporal patterns. Expand
