Brain Activity during Hypnosis (a) Researchers found that the anterior cingulate cortex is activated in all people during the Stroop task. The anterior cingulate cortex (shown in the cross-hairs) is involved in conflict monitoring. (b) However, under hypnosis, highly suggestible people show decreased activation in this brain region compared to less hypnotizable people (Raz et al., 2005).
