Colloquium: Visual processing in Migraineurs: what happens between the headaches?
|Visual processing in Migraineurs: what happens between the headaches?
Migraines are experienced by a substantial proportion of the population and, appropriately, the focus of discussion is usually on the headache phase. There are often visual sequelae associated with the headache but our research has been directed at visual performance in the period between headaches. The talk will describe a number of quite long-lasting changes in visual performance. I will outline the details of those changes, outline our investigation of what other migraine and cognitive characteristics they are associated with, examine and describe our effort to ascertain what aspects of the visual pathways and visual performance are affected, how long the effects last, and describe a re-assuring study examining potential impact on driving behaviour.
Winthrop Professor David Badcock is an ARC Australian Professorial Fellow at The University of Western Australia in the School of Psychology. He received his D.Phil. in Experimental Psychology at Oxford University as a Rhodes Scholar, and then held post-doctoral appointments at UC: Berkeley and Durham University before returning to Australia to Melbourne University. In 1996 he was appointed Professor at The University of Western Australia and served a period as Head of School and is currently an Honorary Professor of Vision Science at The University of Nottingham and President of the Psychology Foundation of Australia.
The focus of his research is on behavioural measurement of human visual performance in both normal and abnormal groups of observers. Currently the laboratory group is running long-term projects examining 1) how humans integrate signals across space and time to perceive both the speed and direction of object and self-motion, 2) the processes that allow us to determine the location of objects within the environment and 3) the processes that help us to integrate local signals to determine object shape. This work is also being applied to determine the nature of the long-lasting changes in visual performance that arise as a consequence of migraine headaches, to early detection and functional understanding of the losses associated with Glaucoma and to an investigation of the unusual pattern of strengths and weaknesses of the visual processing in Autism.
