Sex hormone

- sex hormones were causing brain cells to grow and sprout extensions in teenage brains .' These unfinished— unmyelinated—extension cords, most prominent in the connections from the emotion center of the amygdala to the emotional control center of the prefrontal cortex, need to be coated with a substance called myelin that allows for fast conduction before they can function reliably under stress. This may not happen until the late teens or early adult years. Without the fast connection to the prefrontal cortex, big downloads of emotional impulses often result in immediate, raw behaviors and circuit overload'' (pg 50 female brain)
