(A) Neural time course of somatosensory cortical responses during the paired-pulse stimulation paradigm. As depicted, the individuals with CP had weaker responses overall and hypergated the response to the second stimulation relative to the healthy adult controls. (B) Group-averaged sLORETA images of the somatosensory-evoked cortical activity emanating from the contralateral (left) somatosensory cortex for the first (32–136 ms, left) and the second stimulation (532–636 ms, right). As shown, the strength of the response was significantly weaker following the second stimulation, indicating a gating effect (P = 0.001). (C) The coordinates of the peak voxel from the grand-averaged sLORETA image were used to generate a mask around the somatosensory hand area from which the cortical thickness estimates were generated.
