Based on a wide variety of data, it is now clear that birds and teleost (bony) fish possess a
core “social behavior network” within the basal forebrain and midbrain that is homologous to …

About 10 years ago, a sexually differentiated nucleus was identified in the preoptic area
(POA) of the Japanese quail in the course of studies analyzing the dimorphic mechanisms …

It is currently accepted that most sex differences in brain and behavior do not result from
direct genomic actions, but develop following early exposure to a sexually differentiated …

Seasonal changes in the brain of songbirds are one of the most dramatic examples of
naturally occuring neuroplasticity that have been described in any vertebrate species. In …

The distribution of androgen receptors was studied in the brain of the Japanese quail
(Coturnix japonica), the zebra finch (Taeniopygia guttata), and the canary (Serinus canaria) …

Estrogens play an important role in the control and differentiation of species‐typical behavior
and in endocrine homeostasis of birds, but the distribution and evolution of cells that contain …

A primary goal of the field of behavioral neuroendocrinology is to understand how the brain
modulates complex behavior. Over the last 20 years we have proposed various brain …

Investigations of the cellular and molecular mechanisms of physiology and behaviour have
generally avoided attempts to explain individual differences. The goal has rather been to …

The activational effects of testosterone (T) on male copulatory behavior are mediated by its
aromatization into estradiol. In quail, we have shown by stereotaxic implantation of steroids …

The present study was carried out to determine steroid biosynthesis from cholesterol in the
brain of adult male Japanese quails. As an initial step of the experiments, the concentrations …
