[Anterior cingulate cortex and processing of pain].

Anterior cingulate cortex (ACC), an important part of the limbic system, has extensive connections with other cortical areas and subcortical nuclei and is involved in modulating many functions. In recent years, an increasing body of evidence in eletrophysiology, functional imaging and behavioral study indicates that ACC is closely involved in processing of pain, especially in the affective dimension of pain. This review will focus on the progress in the study of ACC in processing of pain.
