The team is studying the development and function of the retina, thalamus and visual cortex using rodent, cat and primate (including human) models.

Some research focuses on the development of photoreceptors and blood supply in the mammalian eye, and this may lead to advances in the treatment of ophthalmological disorders using interferon and other tools.

Other team members study the ways visual information is processed in two streams through the brain’s thalamus and cortex to tell us “where” and “what”, and relate the psychological experience of vision to this biological mechanism.

Recently, the vision group has conducted research unlocking the secrets of colour vision. The work, focused on colour discrimination in peripheral vision, was published in the prestigious journal Nature.
