HBM_22040_sm_SuppFig1.tif522KSupplementary Figure 1. Tactile detection experiment: a) mean tactile detection calibration results. Detections at stimulus intensity 0% are false alarms, whereas detections from 82-90% are hits. b) Mean correct tactile detections (hits). c) Incorrect tactile detections (false alarms). Tactile control experiment: d) mean reaction times for suprathreshold detection. *Significant difference between means (p < .015). Error bars represent SEM.
HBM_22040_sm_SuppFig2.tif523KSupplementary Figure 2. Auditory control experiment. a) Mean accurate auditory detection rates (hits). b) Incorrect auditory detections (false alarms) c) Likelihood of reporting auditory stimulation (bias) and d) ability to discriminate no auditory stimulation and auditory stimulation trials (sensitivity/ dprime). Error bars represent SEM.
HBM_22040_sm_SuppFig3.TIF4249KSupplementary Figure 3. Cortical surface (Panel A) and axial slices (Panel B) showing low threshold maps (p < .05, uncorrected) of the object, action and interaction (appropriateness) contrasts in the regions significantly activated by the contrast of interest in the main analysis. Images shown are in radiological convention (left side of image corresponds to right side of brain).

HBM_22040_sm_SuppTab1.doc28KSupplementary Table 1. Average across-subject correlation coefficients are shown for regions-of-interest in somatosensory cortex/IPL and MCC, separately for grasps of and withdrawals from painful objects (* p < 0.1; ** p < .05). IPL = inferior parietal lobule, PCG = postcentral gyrus, SI = primary somatosensory cortex, MCC = midcingulate cortex.
