Anterior cingulate cortex
In the human brain, the anterior cingulate cortex (ACC) is the frontal part of the cingulate cortex that resembles a "collar" surrounding the frontal part of the corpus callosum. It consists of Brodmann areas 24, 32, and 33.
Anterior cingulate cortex
It is involved in certain higher-level functions, such as attention allocation,[1] reward anticipation, decision-making, impulse control (e.g. performance monitoring and error detection),[2] and emotion.[3][4]
Tasks[edit]
A typical task that activates the ACC involves eliciting some form of conflict within the participant that can potentially result in an error. One such task is called the Eriksen flanker task and consists of an arrow pointing to the left or right, which is flanked by two distractor arrows creating either compatible (<<<<<) or incompatible (>><>>) trials.[10] Another very common conflict-inducing stimulus that activates the ACC is the Stroop task, which involves naming the color ink of words that are either congruent (RED written in red) or incongruent (RED written in blue).[11] Conflict occurs because people's reading abilities interfere with their attempt to correctly name the word's ink color. A variation of this task is the Counting-Stroop, during which people count either neutral stimuli ('dog' presented four times) or interfering stimuli ('three' presented four times) by pressing a button. Another version of the Stroop task named the Emotional Counting Stroop is identical to the Counting Stroop test, except that it also uses segmented or repeated emotional words such as "murder" during the interference part of the task. Thus, ACC affects decision making of a task.
