Results of absolute power difference for frequency bands, (a) Delta (1-4 Hz), Theta (4-8 Hz), Alpha (8-12 Hz), Beta (12-25 Hz) and High Beta (25-30 Hz), (b) Gamma (30-40 Hz), High Gamma (40-50 Hz), Alpha-I (8-10 Hz), Alpha-II (10-12 Hz), and Beta-I (12-15 Hz). (‘Red’ color indicates high value of the first variable and ‘blue’ color indicates high value of the second variable in the absolute difference).
