Abstract
Areal-intensity combinations required to produce various criterion B-wave magnitudes of the human ERG were studied in three subjects. The relationship describing the intensity (I) and area (A) combinations required to produce a criterion B-wave was log I = -k (log A) + C. The latency of the B-wave decreased with an increase of either area or intensity. A comparison of responses from areas in the fovea, blind spot and periphery indicates that " . . . the human retinal response is primarily aroused by stray light, rather than by the calculated 'focal illumination'."
