Traumatic brain injury. A, Brain lesion overlay map. Brain lesions were identified by CT scans. The color indicates the number of veterans in the frontal lobe lesion group (n = 121) with damage to a given voxel (with blue lowest and red highest). B, Brain volume loss (mean ± SEM). The Met/− and Val/Val BDNF carriers of the frontal lobe lesion group demonstrated no significant percentage volume loss differences in various brain subdivisions (LH, left hemisphere; RH, right hemisphere; vlPFC, ventrolateral prefrontal cortex; vmPFC, ventromedial prefrontal cortex; dmPFC, dorsomedial prefrontal cortex; dlPFC, dorsolateral prefrontal cortex).
