Regions of interest and EEG channels used in offline analysis of amygdala BOLD activity and frontal EEG asymmetry. A) Left amygdala (LA) and right amygdala (RA) ROIs were defined anatomically according to the co-planar stereotaxic atlas of the human brain by Talairach and Tournoux. The ROIs are projected in the figure onto the standard TT_N27 template in the Talairach space. The left hemisphere (L) is to the reader's left. B) Pairs of frontal EEG channels used to quantify frontal EEG asymmetry: F3 (left) and F4 (right), F7 (left) and F8 (right). Cz channel was used as a reference.
