John Stein MA, MSc, BM, BCh, FRCP, FMedSci is emeritus Professor of Neuroscience, Dept. Physiology, Anatomy and Genetics and Fellow of Magdalen College, Oxford. After preclinical studies at New College, Oxford, John trained as a clinical neurologist at St Thomas’s Hospital, London SE1, Leicester and Oxford. From 1970 to 2008, he was Fellow and Tutor in Medicine and Physiological Sciences at Magdalen. In theory "retired", he still teaches neuroscience to medical and psychology students and his research still focuses on the role of vision and nutrition in the control of movement and behaviour in neurological patients, dyslexics and young offenders. John doesn’t cook fish; his brother TV fish chef, Rick Stein, doesn’t do neuroscience!
