Now we will attach the electrodes that will measure eye movement overnight. ​

Take two more of the gold cup electrodes and tape provided and prepare them in the same manner as the others. 

Place one of the electrodes on the prepared area just below the outside of the participant’s left eye with the tape and the wire running diagonally up towards the temple.

Insert the plug into the EOG port 2nd in from the front right of the headbox.

Place the other electrode on the prepared area just above the outside of the participant’s right eye with the tape and wire running diagonally down towards the jaw bone.

Wrap the wire behind the neck and over the left shoulder before inserting the plug into the EOG port 2nd in from the front left of the headbox.
