Abstract
The primate orbitofrontal cortex receives inputs directly from the inferior temporal visual cortex. The orbitofrontal cortex contains visual neurons that learn in one trial which visual object is associated with a reward such as a taste and represent reward value; error neurons that respond if there is a mismatch between the reward expected based on the visual input, and the (taste) reward actually obtained; neurons that respond to the sight of faces encoding information about identity or about expression; and neurons that respond to novel visual stimuli. The human orbitofrontal cortex is activated by visual stimuli that show how much monetary reward has been obtained; and by mismatches in a visual discrimination reversal task between the face expression expected, and that obtained. Discrete lesions of the human orbitofrontal cortex impair visual discrimination reversal and face expression (but not face identity) discrimination. Thus the orbitofrontal cortex plays a fundamental role in visual processing related to emotion.
