Abstract
Utilizing a Maxwellian view optical system to present light flashes to the right eye, electroretinograms (ERG) and visual evoked cortical potentials (VECP) were recorded from normal subjects. The first 120 mS post flash onset was examined. A series of 5 VECP wavelets were recorded with implicit times of 50, 72, 82, 90 and 101 mS, at the highest radiance used. Recordings of ERG in the same experimental session revealed a series of 3 wavelets with implicit times of 23, 30, and 38 mS. It is concluded that the VECP wavelets are not volume conducted from the retina, and probably represent initial arrival of visual information at the cortex or subcortical activity.
