Article Synopsis
- - The study investigates how genetic selection and early social environment affect sociability in quail, focusing on lines selected for high (S+) or low (S-) motivation to approach others.
- - Researchers found distinct differences in brain markers related to social behaviors between the S+ and S- quail, indicating that sex and brain regions play a role in these behaviors.
- - Additionally, introducing S- males to S+ groups improved social skills in S- without changing S+ sociability, suggesting early social interactions can influence genetic outcomes in behavior.
Brain sexual differentiation is a developmental process leading to the establishment of stable neural sex differences. In birds and rodents, this process is largely driven by estrogens during a critical period. In rodents, estrogens drive the masculinization of the brain, a process that partly depends on microglia.

Estrogens derived from brain testosterone aromatization (neuro-estrogens) are critical for the activation of male sexual behavior. Their effects on this behavior are typically associated with long-term changes in circulating levels of testosterone and the transcriptional activity of their liganded nuclear receptors. According to this view, neuro-estrogens would prime the neural circuits controlling the long-term expression of behavior, which would then be acutely regulated by neurotransmitter systems conveying information from the social environment.
