We use brain imaging techniques to investigate the human visual system, both in its normal state and in disease and disorder.
The vision group at FMRIB uses magnetic resonance imaging (MRI) to look at the structure, function and connectivity of the human visual system. We are interested in the functioning of the visual system in its ‘normal’ state in sighted individuals, the changes that occur in people who have disorders of the visual system such as visual impairment or binocular dysfunction and the effects of damage or disease. We use multi-modal MRI, including structural, functional and diffusion MRI and magnetic resonance spectroscopy in the human brain to investigate the relationship with visual function.
One aspect of our research involves investigating how the brain determines the function of a specific region of the brain. In the case of blind subjects who are anophthalmic, in whom the eyes never developed, we are interested in how the visual pathway is recruited by other neural functions. For those who lose visual function later in life, through trauma or a stroke (hemianopia), we have several projects designed to understand the residual function and any re-organisation that occurs to minimise visual deficits (Hannah Willis). Jasleen Jolly and Aislin Sheldon are investigating the structure, function and neurochemistry of the visual cortex in people with inherited retinal disease, to determine the consequences of degeneration on the brain.
Dr Betina Ip is investigating how the neurochemistry of the early visual areas interacts with binocular vision. Dr Ivan Alvarez is applying population receptive field (pRF) approaches to multiple areas of neural processing, including contrasting pRFs quantified in different domains, such as motion and depth.
