Stress-induced reduction in reward-related prefrontal cortex function
Acute psychological stress can trigger normal and abnormal motivated behaviors such as reward seeking, habitual behavior, and drug craving. Animal research suggests that such effects may result from actions of catecholamines and glucocorticoids that converge in brain regions that regulate motivated behaviors and incentive processing. At present, however, little is known about the acute effects ...
متن کاملP142: The Prefrontal Cortex and Stress-Related Psychopathologies
The prefrontal cortex (PFC) plays a central role in processing both normal and pathological affective states and it is among the brain regions most closely associated with stress-related psychopathology in humans. The ventromedial PFC (vmPFC) in particular has been shown to be required for healthy emotional regulation, social function and risk assessment and decision-making. Also this region ex...
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 کاملHeterogeneous reward signals in prefrontal cortex.
Neurons encode upcoming rewards throughout frontal cortex. Recent papers have helped to determine that these signals play different roles in different frontal regions. Neurons in orbitofrontal cortex (PFo) appear to be responsible for calculating the specific value of an expected reward, information that can help efficiently guide decision-making. Similar signals are also present in the cingula...
