Experts have succeeded in mapping the visual activity of the brain in stroke survivors with vision loss
The loss of vision is one of the consequences that can cause stroke, which is the leading cause of acquired disability in adults. Well, a new study has given a glimmer of hope in the rehabilitation and recovery of the view.
A group of scientists have managed to map the visual activity of the brain in survivors of a stroke with loss of sight. The study has been published in the journal 'Frontiers in Neuroscience'. The research has been led by scientists from the University of Nottingham (UK).
As detailed in the article, scientists have combined data from clinical eye tests with brain imaging. All this with the aim of accurately mapping the areas of the brain affected by loss of sight.
In this way, the visual areas of the brain have been identified where function could potentially be improved with rehabilitation. In this case, the study has combined detailed perimetry and multiple brain imaging datasets from four stroke survivors.
Thus, it is shown that perimetry can be augmented with brain imaging data to provide a novel measure of residual visual field function.
Stroke »affects vision through a particular eye»
“A common misconception with stroke-related vision loss is that it affects the vision through one eye in particular”, says the author of the study, Anthony Beh.
