marginally significantp = 0.055
For the alpha + beta (8–30 Hz) band, a significant difference was found in the left leg MI task between C3 and C4 channels ( t = 2.072, p = 0.047); however, the differences in the right leg MI task reached marginally significant (t = −2.003, p = 0.055), suggesting a weaker but still notable neural response.
