Complete activation maps for all regions shown in the table are obtainable from the authors.www.frontiersin.orgJuly Volume Short article Ebner et al.Neural mechanisms of reading emotionsFIGURE Location of vmPFC where satisfied faces angry faces (T contrast): (A) Left ventral medial frontal gyrus,anterior cingulate (BA ; MNI: x ,y ,z ; cluster size: voxels; maximum T value for cluster:). The area of activation represents the T map of the contrast; it can be displayed around the standard reference brain in SPM. The crosshair indicates the peak voxel (nearby maximum) within the area of activation. (B) Bar graphs show the imply left vmPFC parameter estimates (beta values) separately for facial expression and age of participant (acrossage of face); betas for this area of activation identified by the T contrast content faces angry faces have been extracted for every individual from a mm sphere around the local maximum inside the region of activation and averaged to generate a single worth for each and every situation of interest,respectively. (C) Mean distinction in participants’ left vmPFC BOLD response to happy relative to angry faces in relation for the percentage of appropriately identified satisfied relative to angry faces for young and older participants,respectively.left vmPFC (MNI: x ,y ,z ) for the contrast delighted faces angry faces. Followup pairedsample t tests collapsed across the entire sample on extracted beta values in the peak voxel of activation showed that left vmPFC activity was higher for happy than angry [t p .] and neutral [t p .] faces. Figure B presents these extracted beta values separately for young and older adults. The pattern of final results was rather comparable for the two age groups with both young [t p .] and older [t p .] participants showing higher left vmPFC activity for happy than angry faces. Note that vmPFC deactivation is usually observed throughout cognitive tasks and vmPFC activation for the duration of rest (Raichle et al. Selfrelevant andor emotional processing has been related with activation in vmPFC (Johnson et al or with much less deactivation (Ames et al,as observed inside the present study.Subsequent,we have been enthusiastic about examining amygdala activity to delighted when compared with.
