  1. Structures where 51°C activity > 41°C activity, generated by subtraction of 41°C activation maps from 51°C activation maps. Each line represents a cluster within the corresponding VOI. I: ipsilateral to stimulation, C: contralateral to stimulation. Coordinates are based on the stereotactic atlas by Talairach & Tournoux [19]. See Table 1 for structure abbreviations.
