GSTM1 and Aphasia: Oxy-Hb D-values were significantly greater in the left FP area and right superior temporal gyrus compared to the control group. Among non-global aphasia patients, acupuncture improved comprehension and naming tasks, with lower Oxy-Hb in the right visual association cortex and angular gyrus. In global aphasia patients, improvements were seen in the Repetition scores, with higher OxyHb in the right inferior prefrontal gyrus
