Fig, 6. Variation of response from a single goldfish ganglion cell with change in
wavelength of stimulus, Wavelength of stimulus in millimicrons at upper right hand
of each record. The duration of stimulus is indicated by the step in the signal trace
at the base of each series. From Wagner et aZ. (1960).
