Electronystagmography

Principle

Electronystagmography (ENG) is an electrophysiological diagnostic procedure for measuring the movement of the eyes. Several electrodes measure the potential differences that are caused by the eye movements. When looking at a moving, regular, repetitive pattern (e.g. the wagons of a passing train, stripes on a rotating drum), the eyes usually try to follow one point for as long as possible. When the object that the eyes are fixed on leaves the field of vision, the eyes then move rapidly in the opposite direction (regressive saccade) and seek a new fixation point.

Tasks

Record an electronystagmogram of your eye movements while looking at the stripes on a rotating drum.
