Altered intrinsic coupling within ipsilesional motor cortex following the intervention during motor preparation for Hand Opening while Lifting. (A) Schematic of significant decreases in intrinsic coupling (black) in ipsilesional M1 (44 Hz to 25 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. 7 out of 8 participants demonstrate negative coupling within ipsilesional M1 from gamma to beta frequencies following the intervention. Positive values indicate positive coupling, while negative values indicate negative coupling. Error bars represent SEM.
