^aData are mean ± SD and accompanying statistics (post hoc t test) of relative spectral power and peak frequency in the motor-related gamma oscillations in the TD and ASD groups. The power of the bilateral gamma oscillations and peak frequency of contralateral gamma oscillations were significantly different between the two groups.
