ECG, EEG and IMU data for local motion artefact removal

<div>ECG and EEG data collected from a single participant using our custom device with inertial measurement units (IMUs) placed on each electrode, to enable recording of local motion activity (accelerometer and gyroscope) during electrophysiological recordings. This is to enable improved motion artefact removal. Please see paper for description of the device, placement of the electrodes and testing procedure. </div><div><br></div><div>Data is in CSV format, with a sample rate of 220 Hz.</div><div><br></div>If using this data please cite:<div>C.
