Anatomical Basis of Colour Vision

  title={Anatomical Basis of Colour Vision},
  author={W. E. Le Gros Clark},
ONE of the criticisms commonly made in respect of the Young-Helmholtz trichromatic theory of colour vision is the lack of any anatomical evidence for the three sets of sensory receptors in the mammalian retina which are postulated by the theory, or for the three sets of optic nerve fibres which presumably connect them with the brain. It is worth while, therefore, to direct attention to the fact that there is a possible anatomical basis for the three sets of fibres.
