The human electroretinogram in the light and during dark adaptation

On the Oscillatory Potentials of the Human Electroretinogram in Light and Dark Adaptation

“…At more intense background illumination (log IB = 0) the maximum was attained at higher stimulus intensity (about log I, = -1.0). This behaviour of the a-wave and b-wave is in agreement with the findings of Elenius & Ahlas (1961) and Auerbach (1967) although their recording and procedure were different.…”

On the Oscillatory Potentials of the Human Electroretinogram in Light and Dark Adaptation

“…There is no simple method to separate the electrical responses to stimulus flashes into the two mechanisms reflecting scotopic and photopic processes (Granit & Munsterhjelm 1937 Auerbach 1967, and many others). The stimulus flash used (log I, = 0) elicits even after 30 minutes of dark adaptation, a large mixed a-wave and a dominating photopic b-wave in response to a single exposure.…”

Prognostic Value of Visual Evoked Potentials in Occipital Blindness following Basilar Artery Occlusion

“…The retinal responses were photo graphed. Under our conditions the normal steady state amplitudes after completed dark adaptation are of 120-200 //V for the negative and 430-550 /<V for the posi tive wave [2],…”
