Using positron emission tomography (PET), we found contralateral activity correlated with graded cooling stimuli only in the dorsal margin of the middle/posterior insula in humansA. D. Craig; K. Chen; D. Bandy; Eric M. Reiman. Thermosensory activation of insular cortex. Nature Neuroscience 3(2):184-190, 2000. PMID: 10649575. DOI: 10.1038/72131. WOBIB: 56.
In particular, activity within the posterior insula was contralateral to the site of stimulation, tested using regions of interest (ROI) analysis: significant side x site interaction (P = 0Jonathan C.

Significant rCBF increases to 50 degrees C stimuli were found contralaterally in the thalamus, anterior cingulate cortex, premotor cortex, and secondary somatosensory (S2) and posterior insular corticesK.

Both genders showed a bilateral activation of premotor cortex in addition to the activation of a number of contralateral structures, including the posterior insula, anterior cingulate cortex and the cerebellar vermis, during heat painP.
