People with a hemianopic visual field defect are unable to see stimuli presented to the affected quadrants. However, they are still able to imagine visual stimuli in the affected quadrants. In this project, we try to examine whether the affected parts of visual cortex activate while hemianopic participants and age-matched control participants engage in
visual imagery. Moreover, we aim to determine whether hemianopic participants can learn to self-regulate activity in early visual cortex by means of real-time feedback, and if so, to which degree this leads to changes in perception.
This project will use functional magnetic resonance imaging (fMRI), realtime fMRI, and behavioural methods (psychophysics, eye tracking)
