FIG. 4. — Coherence in the motor coretex in controls and mTBI patients for total hemoglobin (Hb) and oxy-Hb. Left and right refer to hemisphere of the brain. The task was right-hand finger tapping. (A) and (C) show data from the resting state, and (B) and (D) show data from the motor task. Bars indicate standard deviation of the mean (*p<0.05; **p<0.01). For total Hb, (A) and (B) there is a significant difference in coherence between left and right hemisphere of mTBI patients during the resting state and during task performance. During task performance, mTBI patients exhibit significantly lower coherence in the right hemisphere, compared to controls. Oxy-Hb (C and D) data also reveal that mTBI patients show a difference in coherence between hemispheres. mTBI, mild traumatic brain injury.
