Abstract: During the past three decades research on the hormonal control of singing has fundamentally altered our basic concepts about how hormones modulate brain function and activate behavior. Exciting discoveries first documented in songbird brains have since been documented in a wide variety of vertebrate species, including humans. Circulating hormones organize sexual dimorphisms in brain structure during development, activate changes in brain structure during adulthood, and modulate the… 

Differential effects of global versus local testosterone on singing behavior and its underlying neural substrate

POM is a key site where T acts to activate copulation and increase song rate, an appetitive sexual behavior in songbirds, but T action in other areas of the brain or periphery is required to enhance the quality of song as well as regulate context-specific vocalizations.

Steroid Hormones Act Transsynaptically within the Forebrain to Regulate Neuronal Phenotype and Song Stereotypy

It is found that ARs and ERs in the song-control nucleus HVC mediate systemic testosterone-induced changes in song stereotypy but not rate, part of a concerted change in key premotor nuclei, enabling stereotyped song.

Social context affects testosterone-induced singing and the volume of song control nuclei in male canaries (Serinus canaria).

The effects of T on singing rate and on the volume of the song control nuclei are modulated by the social environment, including the presence/absence of a potential mate and dominance status among males.

Testosterone‐induced neuroendocrine changes in the medial preoptic area precede song activation and plasticity in song control nuclei of female canaries

Although testosterone increased the number of newborn neurons in HVC rapidly, it is unlikely that these new neurons affect singing behavior before they mature and integrate into functional circuits, and rapid action of testosterone in POM supports its proposed role in controlling singing motivation.

Sex hormone influence on human infants' sound characteristics: melody in spontaneous crying

It is suggested that oestradiol may have effects on the development and function of the auditory–vocal system in human infants that are as powerful as those in vocal-learning animals.

Hormonal acceleration of song development illuminates motor control mechanism in canaries

This research shows that the known effect of testosterone on the neural circuits gives rise to the stereotyped categories of respiratory motor gestures in canaries, and all previously identified categories of adult song were observed.



Circulating estrogens in a male songbird originate in the brain.

It is reported that in zebra finches, the brain synthesizes large quantities of estrogen from androgen and releases this estrogen into blood.

Hormonal Restructuring of the Adult Brain: Basic and Clinical Perspectives

The idea that gonadal hormones could direct brain development and alter synaptic structure was revolutionary, and, in fact, a number of years passed before it was widely accepted that Gonadal hormones programmed cellular structure within areas of the developin brain.

Unraveling the enigma: The role of melatonin in seasonal processes in birds

Data indicate that the interaction of day length and hormones of different classes affects the ability of melatonin to affect seasonal processes in birds, and appears to be modified by the same central, thyroid‐dependent mechanism that controls the reproductive state of birds.

Estrogen synthesis in the male brain triggers development of the avian song control pathway in vitro

It is shown that estrogens are produced autonomously in cultured juvenile male zebra finch brain slices, and this brain-derived estrogen is both necessary and sufficient to trigger formation in vitro of a key male-specific synaptic connection in the telencephalic song control circuit.

The Role of Androgen Metabolism in the Activation of Male Behavior a

Research has highlighted the possibility that many behaviors which have been described as androgen dependent will prove in fact to be dependent on estrogens formed from androgenic precursors, for estrogenic metabolites play an important role in activating male behaviors in many species.

Neuronal production, migration, and differentiation in a vocal control nucleus of the adult female canary brain.

It is concluded that neuronal precursors exist in the HVc ventricular zone that incorporate tritiated thymidine during the S phase preceding their mitosis; after division these cells migrate into, and to some extent beyond, HVm, which seems to be a normally occurring phenomenon in intact adult female canaries.

Neuroendocrine Suppression of Female Courtship in a Wild Passerine: Corticotropin‐Releasing Factor and Endogenous Opioids

The hypothesis that stress neuropeptides orchestrate coping behaviors in wild birds support the hypothesis that an alternate, central mechanism mediates the inhibition of reproductive behavior during stress in passerines.

Intraventricular Infusion of Arginine Vasotocin induces Singing in a Female Songbird

It is hypothesized that both in the breeding and non‐breeding seasons, AVT increases motivation to sing, and the effects of AVT on vocal behavior may not require breeding levels of gonadal steroids and are probably not seasonal.

Modification of synapses in androgen-sensitive muscle. I. Hormonal regulation of acetylcholine receptor number in the songbird syrinx

There is a sex difference in the number of acetylcholine receptors (AChRs) in the syrinx and that alterations in the levels of circulating testosterone can cause changes in AChR number in syringeal muscles, and results suggest that the size or number of endplates in the Syrinx may be increased by circulating testosterone.
