Neural representation of behavioral outcomes in the orbitofrontal cortex.
The orbitofrontal cortex (OFC) is important in processing rewards and other behavioral outcomes. Here, we review from a computational perspective recent progress in understanding this complex function. OFC neurons appear to represent abstract outcome values, which may facilitate the comparison of options, as well as concrete outcome attributes, such as flavor or location, which may enable predi...
متن کاملLateral Orbitofrontal Cortex Involvement in Initial Negative Aesthetic Impression Formation
It is well established that aesthetic appreciation is related with activity in several different brain regions. The identification of the neural correlates of beauty or liking ratings has been the focus of most prior studies. Not much attention has been directed towards the fact that humans are surrounded by objects that lead them to experience aesthetic indifference or leave them with a negati...
متن کاملThe Causal Role of Right Frontopolar Cortex in Moral Judgment, Negative Emotion Induction, and Executive Control
Introduction: Converging evidence suggests that both emotional and cognitive processes are critically involved in moral judgment, and may be mediated by discrete parts of the prefrontal cortex. The current study aimed at investigating the mediatory effect of right Frontopolar Cortex (rFPC) on the way that emotions affect moral judgments. Methods: Six adult patients affected by rFPC and 10 hea...
متن کاملThe role of the orbitofrontal cortex in human discrimination learning.
Several lines of evidence implicate the prefrontal cortex in learning but there is little evidence from studies of human lesion patients to demonstrate the critical role of this structure. To this end, we tested patients with lesions of the frontal lobe (n=36) and healthy controls (n=35) on two learning tasks: the weather prediction task (WPT), and an eight-pair concurrent visual discrimination...
متن کاملSingle-cell and population coding of expected reward probability in the orbitofrontal cortex of the rat.
The orbitofrontal cortex (OFC) has been implicated in decision-making under uncertainty, but it is unknown how information about the probability or uncertainty of future reward is coded by single orbitofrontal neurons and ensembles. We recorded neuronal ensembles in rat OFC during an olfactory discrimination task in which different odor stimuli predicted different reward probabilities. Single-u...
