Answer to Question 1

ANS: B
Electrodes are placed on the skin surface in the periorbital region, specifically approximately 1 cm lateral to the outer canthi of the eyes and offset from the horizontal plane (i.e., 1 cm above the horizontal plane on one side and 1 cm below the horizontal plane on the other side).

Answer to Question 2

ANS: D
The height or depth of the deflection depends on the movement of the eyes relative to the fixed electrodes. Eye movement away from the electrode shows an upward deflection on the elec-trooculogram, and eye movement toward the electrode shows a downward deflection. When looking up with the electrodes in place, the left eye has moved away from its electrode, and the right eye has moved toward its electrode. Because the movement is not directly toward either right or left, the deflections produced by either electrode are smaller than left or right movement.
