Relationships between rapid changes in local aromatase activity and estradiol concentrations in male and female quail brain
Abstract Estradiol-17β (E 2) synthesized in the brain plays a critical role in the activation of
sexual behavior in many vertebrate species. Because E 2 concentrations depend on
aromatization of testosterone, changes in aromatase enzymatic activity (AA) are often
utilized as a proxy to describe E 2 concentrations. Utilizing two types of stimuli (sexual
interactions and acute restraint stress) that have been demonstrated to reliably alter AA
within minutes in opposite directions (sexual interactions= decrease, stress= increase), we …
