Risk-preference differentiates orbitofrontal cortex responses to freely chosen reward outcomes.
To successfully evaluate potential courses of action and choose the most favorable, we must consider the outcomes that may result. Many choices involve risk, our assessment of which may lead us to success or failure in matters financial, legal or health-related. The orbitofrontal cortex (OFC) has been implicated as critical for evaluating choices based on risk. To measure how outcomes of risky ...
متن کاملThe orbitofrontal cortex and reward.
The primate orbitofrontal cortex contains the secondary taste cortex, in which the reward value of taste is represented. It also contains the secondary and tertiary olfactory cortical areas, in which information about the identity and also about the reward value of odors is represented. The orbitofrontal cortex also receives information about the sight of objects and faces from the temporal lob...
متن کاملThe human orbitofrontal cortex monitors outcomes even when no reward is at stake.
The orbitofrontal cortex (OFC) processes the occurrence or omission of anticipated rewards, but clinical evidence suggests that it might serve as a generic outcome monitoring system, independent of tangible reward. In this positron emission tomography (PET) study, normal human subjects performed a series of tasks in which they simply had to predict behind which one of two colored rectangles a d...
متن کاملNeurons in the macaque orbitofrontal cortex code relative preference of both rewarding and aversive outcomes.
Many studies have shown that the orbitofrontal cortex (OFC) is involved in the processing of emotional information. However, although some lines of study showed that the OFC is also involved in negative emotions, few electrophysiological studies have focused on the characteristics of OFC neuronal responses to aversive information at the individual neuron level. On the other hand, a previous stu...
متن کاملEncoding predictive reward value in human amygdala and orbitofrontal cortex.
Adaptive behavior is optimized in organisms that maintain flexible representations of the value of sensory-predictive cues. To identify central representations of predictive reward value in humans, we used reinforcer devaluation while measuring neural activity with functional magnetic resonance imaging. We presented two arbitrary visual stimuli, both before and after olfactory devaluation, in a...
