Auditory experience is critical for vocal learning in songbirds as in humans. Therefore, in a search for neural mechanisms for song learning and recognition, the auditory response properties of neurons in the anterior forebrain (AF) pathway of the songbird brain were investigated. This pathway plays an essential but poorly understood role during the period of song development when auditory feedback is most crucial. Single-unit recordings demonstrated that both the lateral magnocellular nucleus… Expand

Song- and order-selective neurons develop in the songbird anterior forebrain during vocal learning.
TLDR
The anterior forebrain pathway of songbirds has an essential but poorly understood function during song learning, a process requiring auditory experience, and these neurons are one of the clearest examples of experience-dependent acquisition of complex stimulus selectivity. 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. 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
Anterior Forebrain Neurons Develop Selectivity by an Intermediate Stage of Birdsong Learning
TLDR
Extracellular single neuron recordings in 60-d-old zebra finches revealed that AF neurons had significant song and order selectivity for both tutor song and BOS (the bird’s plastic song), raising the possibility that both aspects of the birds’ sensory experience during learning are reflected in properties of AF neurons. Expand
Neural encoding of auditory temporal context in a songbird basal ganglia nucleus, and its independence of birds' song experience
TLDR
It is found that order selectivity strongly depends on the mean syllable duration of individual songs, decreasing markedly as this duration approaches 150–200 ms, which suggests that song neurons integrate acoustic information over a relatively limited time window. Expand
Cellular, Circuit, and Synaptic Mechanisms in Song Learning
TLDR
Experiments that explore the properties of the songbird anterior forebrain pathway show that the AFP contains cells that reflect learning of both BOS and tutor song, as well as developmentally regulated synaptic and circuit mechanisms well‐suited to create temporally organized assemblies of such cells. Expand
Development of selectivity for natural sounds in the songbird auditory forebrain.
TLDR
It is suggested that the emergence of natural sound selectivity in field L could be important for the behavioral development of song recognition. Expand
Song selectivity and sensorimotor signals in vocal learning and production.
TLDR
Experiments that explore a role for the songbird anterior forebrain pathway (AFP), a basal ganglia-forebrain circuit, in evaluating song feedback and modifying vocal output illustrate that sensory and motor processes are highly interrelated in this circuit devoted to vocal learning, as is true for brain areas involved in speech. Expand
Intrinsic and thalamic excitatory inputs onto songbird LMAN neurons differ in their pharmacological and temporal properties.
TLDR
The differences between these two inputs suggest that intrinsic circuitry plays an important role in transforming DLM input patterns into the appropriate LMAN output patterns, as has been suggested for mammalian thalamocortical networks. Expand
Neural auditory selectivity develops in parallel with song.
TLDR
It is reported that the auditory response of the song motor system and motor output are linked early in song development, indicating that selective tuning to BOS mirrors the vocalization that the bird is currently producing. Expand

TLDR
The results suggest that there is a song-selective pathway directly from HVc to RA in addition to the circuit via L-MAN, suggesting that the songbird brain contains multiple auditory pathways specialized for song, which may vary in their functional importance at different stages of learning. 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

TLDR
During song learning the response properties of HVC neurons appear to be dynamically modified, perhaps by auditory feedback from the bird's own vocalizations, both for song learning and for song perception in adult birds. Expand

TLDR
The data suggest that song-specific neurons use long-lasting hyperpolarization as a mechanism to integrate auditory context, an important component of temporal order selectivity, and may increase the precision of spike timing, which could be important for the neural code subserving song learning and production.

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
Selective impairment of song learning following lesions of a forebrain nucleus in the juvenile zebra finch.
TLDR
It is reported here that lesioning Area X disrupts normal song development in juvenile birds, but does not affect the production of stereotyped song by adult birds, and the behavioral results suggest Area X is important for either the acquisition of a song model or the improvement of song through vocal practice.

TLDR
Evidence is provided that HVc neurons encode information about temporal structure by using a variety of mechanisms including syllable-specific inhibition, excitatory postsynaptic potentials with a range of different time courses, and burst-firing nonlinearity. Expand
Hierarchical Organization of Auditory Temporal Context Sensitivity
TLDR
HVc neurons can integrate auditory context over periods much longer than neurons in field L and suggests that additional mechanisms are required to explain the marked sensitivity of HVc neuron to the temporal structure of the bird’s own song. Expand

It is suggested that the parcellation of area X into smaller domains by the projection from IMAN highlights a functional architecture within X, which might correspond to units of motor control, to the representation of acoustic features of song, or both. Expand

TLDR
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. Expand
