The anterior cingulate cortex and pain processing
The neural network that contributes to the suffering which accompanies persistent pain states involves a number of brain regions. Of primary interest is the contribution of the cingulate cortex in processing the affective component of pain. The purpose of this review is to summarize recent data obtained using novel behavioral paradigms in animals based on measuring escape and/or avoidance of a ...
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 کاملMultiple signals in anterior cingulate cortex
Activity in anterior cingulate cortex (ACC) has been linked both to commitment to a course of action, even when it is associated with costs, and to exploring or searching for alternative courses of action. Here we review evidence that this is due to the presence of multiple signals in ACC reflecting the updating of beliefs and internal models of the environment and encoding aspects of choice va...
متن کاملExpectations, gains, and losses in the anterior cingulate cortex.
The anterior cingulate cortex (ACC) participates in evaluating actions and outcomes. Little is known on how action-reward values are processed in ACC and if the context in which actions are performed influences this processing. In the present article, we report ACC unit activity of monkeys performing two tasks. The first task tested whether the encoding of reward values is co ntext dependent-th...
