Comparison (IMAGE) Neural Regeneration Research Caption This is a comparison of gray matter volume in brain areas using voxel-based morphometry analysis. (a) The left superior parietal lobule (post-traumatic stress disorder patients group < trauma control group); (b) the right superior frontal gyrus (post-traumatic stress disorder patients group < trauma control group); (c) the right lingual gyrus (post-traumatic stress disorder patients group < symptoms-improved group); (d) the right middle occipital gyrus (symptoms-improved group < trauma control group); (e) the left middle frontal gyrus (symptoms-improved group < trauma control group). A: Anterior; P: posterior; L: left; R: right. Data were analyzed using one-way analysis of covariance and adjusted with Alphasim. The color bar in each image represents the T value, and the higher T values indicate greater differences.
