| Citation | Distinguished for his work on the physiology of vision (underlined).
Most of the recent advances in physiology lie in the application of new equiplent to old problems. Bridley's achievements have resulted rather in observing what others have overlooked and by his powerful analysis as to the significance. Thus by studying the way that colour matches break down under very strong illumination he was able to deduce for the first time the spectral sensitivity of the visual pigments in the cones, and estimate the density of the red-sensitive pigment, its photosensitivity and its rate of regeneration. Amongst other work he has made important contributions to the analysis of the electroretinogram, the (subjective) electric phosphene and the nature of after-images. |
