Fig 1a and b: Subgenual prefrontal cortex (SGPFC) response to a monetary incentive delay task in 11 special force (SF) soldiers and 11 healthy civilian controls. (a) Mean (± SE) % BOLD signal change in the right SGPFC region of interest in response to a high reward and neutral cue after covarying for IQ [group × condition interaction: F_(1,19)=5.29, p=0.03; effect size Cohen’s d=1.102]. (b) Regional activation in the right SGFC rendered on a single-subject T1 image [P <.01 (t = 2.85)].
Fig 1c and d: Ventral striatal response to a monetary incentive delay task in 11 special force (SF) soldiers and 11 healthy civilian controls. (c) Mean (± SE) % BOLD signal change in the right accumbens (Acc) region of interest in response to a high reward and neutral cue after covarying for IQ [(group × condition interaction: F_(1,19)=3.74, p=0.07; effect size Cohen’s d=1.005). (d) Regional activation in the right Acc rendered on a single-subject T1 image. [P <.01 (t = 2.85)].
