The researchers proposed that these aromatase-expressing regions of the brain could form an interconnected network that regulates sex-specific behaviors, but Shah cautioned that much more research needs to be done on the role of the development of sex-specific neural pathways, and that many additional factors, including genetics and socialization, could contribute to sexual differentiation.--Co-authors on the paper include UCSF researchers Devanand S.
