dopaminergic activity in the medial prefrontal cortex modulates fear conditioning
the purpose of the present study was to determine the role of medial prefrontal cortex (mpfc) dopaminergic system in fear conditioning response considering individual differences. animals were initially counterbalanced and classified based on open field test, and then were given a single infusion of the dopamine agonist, amphetamine (amph) and antagonist, clozapine (clz) into the medial prefron...
متن کاملPerceived life stress exposure modulates reward-related medial prefrontal cortex responses to acute stress in depression.
INTRODUCTION Major depressive disorder (MDD) is often precipitated by life stress and growing evidence suggests that stress-induced alterations in reward processing may contribute to such risk. However, no human imaging studies have examined how recent life stress exposure modulates the neural systems that underlie reward processing in depressed and healthy individuals. METHODS In this proof-...

متن کاملMedial prefrontal cortex stimulation modulates the processing of conditioned fear
The extinction of conditioned fear depends on an efficient interplay between the amygdala and the medial prefrontal cortex (mPFC). In rats, high-frequency electrical mPFC stimulation has been shown to improve extinction by means of a reduction of amygdala activity. However, so far it is unclear whether stimulation of homologues regions in humans might have similar beneficial effects. Healthy vo...
متن کاملNoradrenergic innervation of the dorsal medial prefrontal cortex modulates hypothalamo-pituitary-adrenal responses to acute emotional stress.
The medial prefrontal cortex (mPFC) has been proposed to play a role in the inhibition of hypothalamo-pituitary-adrenal (HPA) responses to emotional stress via influences on neuroendocrine effector mechanisms housed in the paraventricular hypothalamic nucleus (PVH). Previous work also suggests an involvement of the locus ceruleus (LC) in behavioral and neuroendocrine responses to a variety of a...
