Neurons in area 24b of the rabbit anterior cingulate cortex are activated in response to painful stimuli. Like the nociceptive neurons in the medial thalamic nucleus that innervate the anterior cingulate cortex, area 24b neurons have large receptive fields that are often bilateral. The neurons are specific to nociceptive information, i.e., they are not activated by nonpainful somatosensory stimulation, and they show some specificity to the nature of the painful stimulus. These neurons are also activated during the learning of responses that lead to the avoidance of painful stimuli.

Lesions in the anterior cingulate cortex retard such learning and have been shown to reduce pain sensitivity in monkeys.
