The eye has often been considered to be a "window to the soul". Accordingly, much research in psychology, neuroscience, computer science, psychiatry and neurology has made use of oculographic recordings in the study of the fundamental processes that underlie cognition, perception and motor control, as well as their alterations in psychiatric and neurological disorders. In this talk, I will present data from a number of our recent studies, including the Rhineland Study, a population-based cohort study in Bonn, Germany. Our findings show that many oculomotor measures deteriorate with age, particularly smooth pursuit velocity, prosaccade and antisaccade latency, and the rate of direction errors on the antisaccade task. Interestingly, some of that age-related variance is accounted for by reductions in grey matter volume and cortical thickness. Finally, I will summarise work showing that some oculomotor measures are impaired in schizophrenia, and I will present evidence demonstrating that these impairments can be explained in part by molecular genetic factors.
Ulrich Ettinger is Professor of Cognitive Psychology and Experimental Clinical Psychology in the Department of Psychology at the University of Bonn, Germany. He studied psychology at Goldsmiths College and neuroscience at King's College London, UK, and obtained his PhD on oculomotor endophenotypes of schizophrenia from the University of London in 2003. Following his PhD, Ulrich held a number of postdoctoral positions including a Richard H. Tomlinson Postdoctoral Research Fellowship at the Department of Psychology und Douglas Hospital, McGill University, Montreal, Canada, and fellowships from NIHR, ESCR and MRC (UK) at King's College London. In 2009, he became head of an Emmy Noether Group, a DFG funded junior researcher programme, at the University of Munich, and in 2012 he was appointed professor at the University of Bonn. His research applies experimental, psychometric, neuroimaging and pharmacological approaches to the study of cognition and brain function in healthy individuals and those with psychiatric disorders.
