Birdsong is controlled in part by a discrete network of interconnected brain nuclei regulated
in turn by steroid hormones and environmental stimuli. This complex interaction results in …

The vocal control nucleus HVC in songbirds has emerged as a widespread model system to
study adult brain plasticity in response to changes in the hormonal and social environment. I …

We present the transcriptomic changes underlying the development of an extreme
neuroanatomical sex difference. The robust nucleus of the arcopallium (RA) is a key …

Gonadal hormone activities mediated by androgen and estrogen receptors, along with cell-
autonomous mechanisms arising from the absence of sex-chromosome dosage …

Birdsong is a relatively well-studied behavior, both due to its importance as a model for
vocal production learning and as an intriguing complex social behavior. Until the last few …

Adult treatments with testosterone (T) do not activate singing behavior nor promote growth of
song control nuclei to the same extent in male and female canaries (Serinus canaria) …

Highly sensitive in situ hybridization procedures (RNAScope) were used to quantify the
expression of three dopamine receptors (Drd1, Drd2, and Drd3) in two song control nuclei …

The avian homologue of oxytocin (OT), formerly called mesotocin, influences social
behaviors in songbirds and potentially song production. We sought to characterize the …

Background and Aim: Pelung chicken Gallus gallus gallus (Linnaeus, 1758) is a chicken
endemic to Cianjur, West Java, Indonesia. This study aimed to determine the effects of zinc …

Background. Behavioral sex differences are widespread in the animal world. These
differences can be qualitative (ie, behavior present in one sex but not the other, a true sex …
