In this set of lectures, Jeremy Nathans explores the molecular mechanisms within the retina that mediate the first steps in vision and discusses photoreceptors that mediate human color vision. The first lecture focuses on the structure of the light sensing receptors, the intracellular signals that are triggered by light absorption, and the ways in which the retina extracts information from a complex scene.
The second lecture focuses on the photoreceptors that mediate human color vision and the molecular basis for the common inherited anomalies of color vision.
The third lecture describes recent work on the evolution of trichromatic color vision in humans and our primate relatives.
Jeremy Nathans is a Professor in the Departments of Molecular Biology and Genetics, Neuroscience, and Ophthalmology at the Johns Hopkins University School of Medicine. He is also an Investigator of the Howard Hughes Medical Institute. He received B.S. degrees in Chemistry and in Life Sciences from the Massachusetts Institute of Technology in 1979, and Ph.D….
