Talairach coordinates (x, y, z) and maxima (Z-score) relative to the commonalities in brain activation (conjunction analysis) in the contrast “attentional task” versus “passive viewing” in normal, high, and low arousal (for the experimental subjects) and in three sessions of normal arousal (for the control subjects). sP, Superior parietal gyrus; iP, intraparietal sulcus/postcentral gyrus; pF, prefrontal cortex; pM, premotor cortex; aC, anterior cingulate; O, occipital cortex; Ce, cerebellum.
