Fig 3. Average values of the GBA (PSD in μV²) at rest and during the movement of both hands.

The values are represented according to the time intervals (initial, middle, final) for the right-handed subjects (n = 11). GBA = Gamma Band Activity, B = Basal, MR = Motor Right, ML = Motor Left, INI = Initial, MID = Middle, FIN = Final. Asterisks indicate statistically significant difference.
