title: The response of rabbit ciliary nerve to luminance intensity.
abstract: Using cervical sympathectomized and immobilized rabbits, the relationship between the luminance intensity and the magnitude of the response in pupillo-constrictor units of the ciliary nerve was investigated. It was revealed that the intensity--response relationship of the units closely resembled that of retinal receptors. Therefore, it would seem that retinal information concerning luminance is relayed without alteratin to the ciliary nerve in spite of passing through a number of synapses.
