Welcome to the web pages of the St Paul's Visuomotor Group.

Based in the oculomotor labs of Dr Paul C. Knox in the Institute of Ageing and Chronic Diseaseís Department of Eye and Vision Science (which have just moved into the new Apex building in the University), we have a number of research projects in which we are investigating the control of eye movement and visually guided behaviour in health, ageing and disease, the effect of visual illusions, and the wider impact of visual disability. Details of ongoing projects and publications can be found on the appropriate pages. Recent publications and other information are listed below.
