BA 20 , in both frontal lobes right: The latter identified many of the erotic pictures as negative, especially those depicting males and male couples.
The average beta value of all voxels within the respective cluster as reported in table 2 was used. Then, activation patterns during event-related and blocked stimulus presentation inside this VOI were compared using paired t-tests. It is a huge part of who we are and the part of ourselves we think and live from. Positive erotic picture stimuli for emotion research in heterosexual females.
