visual processing • amblyopia • psychophysics • brain imaging
My research focuses on understanding low level vision, in particular cortical plasticity in the adult. We use a range of different techniques including psychophysics, brain stimulation (TMS and tDCS), brain imaging (fMRI, EEG and MEG) and computational modelling to better understand normal visual cortical function and how it can be modulated. One key application of this work is to a condition called amblyopia. This is the most common form of unilateral blindness in the adult population, with an incidence of three per cent, but currently there is no treatment beyond 17 years of age. We have developed a novel new treatment and we are also developing a related approach for children with this condition.
