Testosterone programs adult social behavior before and during, but not after, adolescence.
Whereas the adolescent brain is a major target for gonadal hormones, our understanding of hormonal influences on adolescent neural and behavioral development remains limited. These experiments investigated how variations in the timing of testosterone (T) exposure, relative to adolescence, alters the strength of steroid-sensitive neural circuits underlying social behavior in male Syrian hamsters...
متن کاملSexual experience and testosterone during adolescence alter adult neuronal morphology and behavior.
Steroid hormones released immediately before and after birth provoke sexual differentiation of neural circuits. Further, steroid hormones secreted during adolescence also exert long lasting effects on the nervous system. Hormones secreted during development may act through two distinct pathways: (1) hormones can directly affect neuron and synapse elimination and (2) endocrine changes in the ner...
متن کاملEffects of social conditions during adolescence on courtship and aggressive behavior are not abolished by adult social experience.
Social experience during adolescence has long-lasting consequences for adult social behavior in many species. In zebra finches, individuals reared in pairs during adolescence start to court females faster, sing more courtship motifs to females and are more aggressive compared with group-reared males. We investigated whether such differences are stable during adulthood or can be abolished by nov...
متن کاملTestosterone and Social Behavior
Popular perceptions of the effect of testosterone on “manly” behavior are inaccurate. We need to move away from such simplistic notions by treating testosterone as one component along with other physiological, psychological and sociological variables in interactive and reciprocal models of behavior. Several hormones can now be measured in saliva, removing the need for blood samples. Conceptual ...
متن کاملEndogenous Testosterone Modulates Prefrontal–Amygdala Connectivity during Social Emotional Behavior
It is clear that the steroid hormone testosterone plays an important role in the regulation of social emotional behavior, but it remains unknown which neural circuits mediate these hormonal influences in humans. We investigated the modulatory effects of endogenous testosterone on the control of social emotional behavior by applying functional magnetic resonance imaging while healthy male partic...
