Social Context–Induced Song Variation Affects Female Behavior and Gene Expression

It is demonstrated that females detect and prefer the features of directed song and suggest that high-level auditory areas including the CMM are involved in this social perception.

Singing modulates parvalbumin interneurons throughout songbird forebrain vocal control circuitry

Overall, singing but not social context significantly affected EGR1 expression in PV neurons throughout the vocal control nuclei, and singing altered the amount of PV expression in neurons in HVC and Area X and that distinct PV interneuron types in Area X exhibited different patterns of modulation by singing.

Social behavior modulates songbird interpeduncular nucleus function

A possible source of modulation of singing-related activity in the anterior forebrain nuclei lateral magnocellular anterior nidopallium and Area X is investigated, the midbrain interpeduncular nucleus, by monitoring immediate early genes and synaptic activity.

Forebrain circuits underlying the social modulation of vocal communication signals

The pattern of context‐dependent differences in EGR‐1 expression in the Bengalese finch was highly similar to that in the zebra finch and suggests that social context affects song structure by modulating activity throughout vocal control nuclei.

Modulation of singing‐related activity in the songbird ventral tegmental area by social context

Recording from neurons in the ventral tegmental area of the VTA suggests that VTA activity could carry signals related to motivational aspects of singing, as well as more primary sensory and motor signals.

Male mice song syntax depends on social contexts and influences female preferences

The results suggest that although mice have a much more limited ability of song modification, they could still be used as animal models for understanding some vocal communication features that songbirds are used for.

Long-term Devocalization of Zebra Finches.

A new surgical procedure is developed to relatively easily and almost completely devocalize female zebra finches semi-permanently, without affecting other behaviors, which enables researchers to record directed songs with almost no contamination by female calls.

Social context modulates singing-related neural activity in the songbird forebrain

It is shown that, in the adult zebra finch, the pattern of singing-related neural activity in several high-level brain areas specialized for song learning is dependent on whether a bird sings by itself or to another bird; thus, this activity can indicate not only that a bird is singing but also the social context of the song.

Natural Changes in Brain Temperature Underlie Variations in Song Tempo during a Mating Behavior

It is shown that brain temperature recorded in freely behaving male finches exhibits a global increase in response to the presentation of a female bird, which strongly correlates with, and largely explains, the faster tempo of songs directed at a female compared to songs produced in social isolation.

The act of singing, but not hearing song, induces a rapid and striking increase in expression of the transcriptional regulator ZENK in the high vocal center and other song nuclei.

Brain gene regulation by territorial singing behavior in freely ranging songbirds

It is concluded that singing behavior in the context of territorial defense is associated with gene regulation in brain centers that control song perception and production, and that behaviorally regulated gene expression can be used to investigate brain areas involved in the natural behaviors of freely ranging animals.

It is suggested that the learned features of oscine songbird vocalizations are controlled by a telencephalic pathway that acts in concert with other pathways responsible for simpler, unlearned vocalizations.

Temporal Hierarchical Control of Singing in Birds

In zebra finches, songs include notes and syllables (groups of notes) delivered in fixed sequences, and neurons in the forebrain nucleus HVc exhibited reliable changes in activity rates whose patterns were uniquely associated with syllable identity.

Circuits, hormones, and learning: vocal behavior in songbirds.

New data on the architecture of the song system is described that suggests strong similarities between the songbird vocal control system and neural circuits for memory, cognition, and use-dependent plasticity in the mammalian brain.

Identification of a forebrain motor programming network for the learned song of zebra finches

The study of the motor control system for birdsong has provided the most direct evidence to date for localizing the programming of a skilled motor sequence to the telencephalon and the observation that unilateral forebrain perturbation was sufficient to alter the pattern of this bilaterally organized behavior suggests that (non-auditory) feedback pathways to the forebrain exist to coordinate the two hemispheres during singing.

ZENK protein regulation by song in the brain of songbirds

ZENK protein regulation can be used to assess activation of brain areas involved in perceptual and motor aspects of song in zebra finches and canaries after presentation of song playbacks.

The principal aims in the present study were to determine exactly how similar the vocal control system in budgerigars is to that in songbirds and whether the vocal Control System in budgers receives auditory inputes from areas other than Field L.
