Project description
Humans shift their gaze from detail to detail by using eye movements. Although each eye movement changes the position of the image that is reflected to the retinas of the eyes, we experience a spatially stable stream of vision that is uninterrupted by eye movements. To achieve this stable stream of vision, the brain must take into account the eye movement, and temporarily suppress vision during rapid gaze shifts. How the brain does this, remains to be solved. The present research approaches this question from two perspectives. First, we test a theory according to which visual stability is achieved by suppressing the ability of visual brain areas to communicate with higher brain areas during eye movements. Second, we study whether the disruption of these mechanisms leads to a breakdown in visual stability in specific clinical populations (e.g. Parkinson’s disease). Deficits in visual stability could compromise spatial cognition and lead to symptoms such as vertigo and hallucinations.
