This is a report of dysjunctive eye movements, both spatial and temporal, that were noted while recording eye movements by means of electro-oculography.1,2 It has recently been stated that "... the nonfixing eye follows the movements of the fixating eye quite faithfully."3 It is the purpose of this report to demonstrate, with electrooculographic records, the independent nature of each eye, as well as the dysjunctive eye movement patterns.
Electro-oculography is based upon the cornea-retinal potential, which was first demonstrated by du Bois-Reymond4 in 1849. The eye acts as a small dipole, so that, if electrodes are placed about the eye, a change in the electrode potential will occur when the cornea becomes closer to one electrode and farther from the diametrically opposite electrode. A record of the eye movements is obtained when the electrodes are placed in the principle meridians, vertical and horizontal, of each eye and recorded
