Further, as shown in Figs. 8 & 9, major gender differences observed in LORETA were: 1) during both loss and gain conditions, females activated both anterior and posterior areas while males activated either anterior or posterior areas, 2) differences across task conditions in the ORP activity were observed in males (the larger amounts of loss and gain (i.e. +50 and −50) had significantly higher activity in medial frontal gyrus (BA 10, 11) and anterior cingulate cortex (BA 32) as compared to the smaller amounts (+10 and −10) but not in females, and 3) Specific brain areas have been activated during the comparisons within gender, valence, and amount.
