Visual rehabilitation after stroke guided by anatomical and functional neuroimaging (360G-Wellcome-211896_Z_18_Z)

£0

Approximately 60% of stroke survivors are left with significant visual impairment such as visual field loss. There are currently no effective rehabilitations for visual field loss, and perceptual retraining has only been shown to be effective for specific stimuli and visual field locations, rather than generalising to an overall improvement. However, functional imaging responses can reveal spared striate and extra striate cortex which opens up the possibility of retraining residual brain networks to detect and discriminate visual input in the visual field thought to be cortically blind. This project aims to assess the feasibility of combining diffusion weighted measurements with functional MRI data to establish maps of residual visual function and anatomical connectivity in stroke survivors with visual field loss. Furthermore, whether these spared areas support the generation of conscious visual perception in the damaged visual field. This will be perfomed on existing data from one stroke survivor, who will then return for behavioural experiments which present stimuli in areas that have been determined to be spared. With the knowledge gained in this project, we will be able to maximise the benefit of visual rehabilitation by targeting the training interventions to specific locations and kinds of stimuli.
