Qualitative and quantitative recording of these oscillations is called nystagmography. Electronystagmography (ENG) and electrooculography (EOG) are based on the recording of variations of the standing potential. The existence of an electrical potential difference between the anterior and the posterior segment of the eye was demonstrated first by De Bois Raymond in 1849 and later studied by Dewar, who considered it to be a simple artifact. Mayers thought the observed potentials were of muscular origin. Mowrer, Rush and Miller showed it to be a corneo retinal potential and this was confirmed by Noell.en10.1159/000307115info:eu-repo/semantics/closedAccessArticle1691991104413208Q1
