There were nine different recording conditions: i) resting state with eyes open, ii) mixed median nerve stimulation (arm nerve), iii) mixed tibial nerve stimulation (leg nerve), iv) sensory nerve stimulation of the index finger, v) sensory nerve stimulation of the middle finger, vi) simultaneous senory nerve stimulation of the index and middle finger, vii) sensory nerve stimulation to the first toe, viii) sensory nerve stimulation to the second toe, ix) simultaneous senory nerve stimulation to the first and second toe. For each participant, there is i) the simultaneous EEG-ESG-ENG-EMG-recording which also includes electrocardiographic and respiratory signals, ii) ESG electrode positions.
