Adolescent peer interaction and trait surgency weaken medial prefrontal cortex responses to failure.
Adolescent risk taking has been known to increase in the presence of peers. We hypothesized that peer interaction reduces the activation of the medial prefrontal cortex (mPFC) that is required for self-regulation of reward-driven behavior. We also expected that mPFC activity would be reduced more in those with greater surgency, a composite trait of behavioral approach, sensation seeking and pos...
متن کاملInverse amygdala and medial prefrontal cortex responses to surprised faces.
Here we show inverse fMRI activation patterns in amygdala and medial prefrontal cortex (mPFC) depending upon whether subjects interpreted surprised facial expressions positively or negatively. More negative interpretations of surprised faces were associated with greater signal changes in the right ventral amygdala, while more positive interpretations were associated with greater signal changes ...
متن کاملprelimbic of medial prefrontal cortex GABA modulation through testosterone on spatial learning and memory
Prefrontal cortex (PFC) is involved in multiple functions including attentional , spatial orientation, short and long-term memory. Our previous study indicated that microinjection of testosterone in CA1 impaired spatial learning and memory. Some evidence suggests that impairment effect of testosterone is mediated by GABAergic system. In the present study, we investigated the interaction of test...
