Reduced interhemispheric coupling following the intervention during motor preparation for Hand Opening on the table. (A) Schematic of significant decreases in coupling (black) from ipsilesional M1 (47 Hz) to contralesional M1 (36 Hz) within the motor network (light gray) following the intervention. None of the other region interactions (light gray arrows) showed significant changes pre to post intervention. (B) Average coupling strength data with individual data overlaid pre/post intervention for the connection depicted in A. 6 out of 8 participants demonstrate a reduction in coupling strength for this M1-M1 connection within gamma frequencies. Positive values indicate positive coupling, while negative values indicate negative coupling. Error bars represent SEM.
