Question

Quizplus · Accepted Answer

The anterior cingulate cortex (ACC) is involved in the emotional processing of pain and becomes more active in anticipation of pain. This suggests that Michael's ACC is likely to become more active as he anticipates the pain of the needle insertion. In contrast, the intralaminar nuclei of the thalamus are involved in pain perception, but they do not become more active in anticipation of pain. The posterior cingulate cortex (PCC) is associated with the default mode network and self-referential processing, but not specifically with pain processing. The somatosensory cortex is involved in the perception of physical sensations, but it does not become more active in anticipation of pain.
