Professor Barry Winkler, PhD, of the Eye Research Institute of Oakland University will give his final lecture before official retirement this term. March 19th, in Oakland Center, on our campus. Barry Winkler has made important contributions to understanding how the neural retina functions, in great detail over 40 years as an NIH funded investigator. Many people, all over the world, have learned where the cellular components of the basic ERG (Electro Retina Gram) come from, from both his papers and from attending his seminars.
