Experimental setup during EEG acquisition and BMI-control: A 64-channel EEG system was used for recording brain activity.
During motor imagery and BMI control, the instructions and the visual stimuli, including the BMI feedback as shown in the picture, were presented on a computer screen. Participants sat comfortably in front of the screen, keeping their hands on their thighs with the palms up.
