### <i> Biosignal Recording and EEG Parameterisation <i>
The EEG recordings were performed with electrodes secured at sites FP1, FP2, F7, F3, Fz, F4, F8, T3, C3, Cz, C4, T4, T5, P3, Pz,
P4, T6, O1, O2 with 19-channel equipment (WAVi). A headset containing the electrodes is placed on the patient. The electrodes are
examined to ensure quality contact. If contact is unacceptable, conductive gel can be added and the eSocs can be rubbed along
the scalp to exfoliate the location of the electrode in order to assist in gaining proper contact. Once contact is deemed
acceptable, a auditory P300 Eyes Closed Protocol is run. The patient is instructed to avoid any synchronized motions and blinks
during the P300 test as this will affect the quality of the data.
