Data-set: Movement Imagination channel 1: EEG of C3 channel 2: EEG of C4 channel 3: onset indicates second 2 of each trial The data is not triggered and not artifact corrected. Sampling frequency: 128 Hz Calibration: 1 in MATLAB equals to 1/50 µV. Therefore, multiply the data by 50 to have 1 µV as 1 represented in MATLAB.
