Human electroretinograms ERG of 191 subjects were taken in the ERG laboratories of the Bascom Palmer Eye Institute, with reference to 1 doubling of a and b components, 2 correlation with dark - adaptation, 3 general inhibitory effects, 4 general systemic ERG inhibition and enhancement, 5 binocular interaction effects, and 6 ERG in relation to maturation. Supportive animal studies are included in this research. The doubling of the b - wave may be related to photophobia and skin pigmentation. The ERG can be used as an objective index of dark -adaptation. The absence of the b - wave in the night blind is interpreted as an example of possible specific inhibition rather than of specific loss of structure. Possible binocular interaction effects are noted. The role of the ERG in general systemic retinal functioning is noted. The ERG in neonates presents clear evidence of the existence of dark - adaptation at birth. The chemical maintenance of the ERG in the isolated animal retina is reported.
