Anterior cingulate cortex
It appears to play a role in a wide variety of autonomic functions, such as regulating blood pressure and heart rate.
Anterior cingulate cortex
The most basic form of ACC theory states that the ACC is involved with error detection. Evidence has been derived from studies involving a Stroop task. However, ACC is also active during correct response, and this has been shown using a letter task, whereby participants had to respond to the letter X after an A was presented and ignore all other letter combinations with some letters more competitive than others. They found that for more competitive stimuli ACC activation was greater.
