Now take the eye electrodes and stick one to the prepared area beside and just above the outer right eye. 

Take the other electrode and stick it to the prepared area beside and just below the outer left eye (between the edge of the eye and the top of the cheekbone).

The right eye electrode plugs into the port labeled EOG on the far left of the headbox.

The left eye electrode plugs into the EOG port on the far right of the headbox.

Just like the electrodes behind the ear, it is important that these are not confused .
