Crick received his Ph.D. in 1954. He remained with the Medical Research Council at the Cavendish Laboratory, and became head of the Division of Molecular Genetics in 1962, continuing to work closely with Sydney Brenner. He turned his attention to embryology in the mid-1960s, and in 1975 he moved to the Salk Institute in La Jolla, California, to pursue neurobiology, an interest that had vied with molecular biology from the very beginning of his career. At the Salk Institute, in collaboration with Christof Koch, he studies the neural correlates of conscious visual experience, seeking to understand how neuron firing patterns correspond to the conscious experience of seeing.
