  1. Shown are the median number of voxels (min, max) (i.e., volume of activation) and percent change in BOLD signal (mean ± SE) in different brain areas in response to aggressive motivation following SRX251 and fluoxetine treatment. These BOLD time course data were compared by taking the fifty data points following stimulus presentation for each condition and using a repeated measures 2-way ANOVA to assess if there was a significant difference between conditions. Significant differences in volume of activation between SRX251 and fluoxetine for each brain region are shown. The numbers in parenthesis shown after each brain area is the average number of voxels from ten subjects that occupy that brain volume after registration in the 3D atlas. Brain areas shown in bold italic comprise the putative neural circuit of aggressive motivation. p < 0.05*; p < 0.01**
