n.
an electrical method of recording eye movements. Tiny electrodes are attached to the skin at the inner and outer corners of the eye, and as the eye moves an alteration in the potential between these electrodes is recorded. The size of this potential at rest also gives an indication of the health of the retina. The recording itself is called an electrooculogram (EOG).
