Age-Dependent Effects of Testosterone on Emotion Control in Brain Development.

Testosterone has a dual role in brain development, affecting emotion control differently during adolescence and adulthood. Brain imaging scans of 71 participants showed that higher testosterone levels enhance the engagement of the brain's anterior prefrontal cortex (aPFC) during adolescence, but impede it during young adulthood. The study highlights the changing role of testosterone across developmental periods and its link with mood disorders that often arise during adolescence.
