Stock, J.B., A.M. Stock, and J.M. Mottonen. Signal transduction in bacteria. The author, a Howard Hughes Medical Institute investigator, discusses how the perception of color is detected by cone photoreceptors in the retina and interpreted by various nerve sites in the brain. By isolating and analyzing the genes for the four proteins in the eye responsible for detecting light, scientists have a means for understanding the molecular basis of color blindness in humans. Pennsylvania Biotechnology Association.
Specific genes are responsible for the development of eyes.
Schnapf, J.L. and D.A. Baylor. How photoreceptor cells respond to light. This article examines how rods and cones, the photoreceptors found in the retina of the eye, respond in the visual process and generate electrical signals that are then transmitted to the brain. Society for Neuroscience. This four-page brochure discusses types of eye movements and why they are crucial.
