Reward encoding in the monkey anterior cingulate cortex.
The anterior cingulate cortex (ACC) is known to play a crucial role in the fast adaptations of behavior based on immediate reward values. What is less certain is whether the ACC is also involved in long-term adaptations to situations with uncertain outcomes. To study this issue, we placed macaque monkeys in a probabilistic context in which the appropriate strategy to maximize reward was to iden...

متن کاملApplication of magnetic resonance spectroscopy for evaluating metabolic alteration in anterior cingulate cortex in Alzheimer's disease
Introduction: Alzheimer’s disease (AD) is the most common cause of dementia worldwide. Mild cognitive impairment (MCI) is often the prodromal stage to AD. Most patients with MCI harbor the pathologic changes of AD and demonstrate transition to AD at a rate of 10–15% per year. Accumulating evidence indicates that the asymmetry changes of left and right brain have happened in the early stage of A...
متن کاملAnterior cingulate cortex regulation of sympathetic activity.
the anterior cingulate cortex (ACC) is active in such a wide variety of cognitive and emotional tasks has become an important issue in recent research. In this issue of Brain, Critchley et al. (2003) report changes in heart rate in both cognitive and motor tasks related to the strength of activation in the ACC. They interpret their ®ndings as supporting a view that the anterior cingulate is inv...
متن کاملSurprise signals in anterior cingulate cortex: neuronal encoding of unsigned reward prediction errors driving adjustment in behavior.
In attentional models of learning, associations between actions and subsequent rewards are stronger when outcomes are surprising, regardless of their valence. Despite the behavioral evidence that surprising outcomes drive learning, neural correlates of unsigned reward prediction errors remain elusive. Here we show that in a probabilistic choice task, trial-to-trial variations in preference trac...
