Spectral response curves of single cones in the carp.

Abstract Single cone spectral response curves were obtained with the aid of specially designed equipment. Statistical analysis of 142 records selected from hundreds, based solely on the greatest signal-to-noise ratio, revealed three groups of cones; the red cones (74 per cent) with the peaking wavelength at 611±23mμ, green cones (10 per cent) at 529±14mμ , and blue cones (16 per cent at 462±15mμ). These peaking wavelengths are in close accord with those of single cone absorption spectra measured by Marks and MacNichol in the goldfish by a microspectrophotometer. Apparently, Young's trichromatic theory applies at the photoreceptor level in Cyprinidae.
