The Surprising Cognitive Control of Tiny Eye Movements.

Researchers at Weill Cornell Medicine have discovered that ocular drift, a subtle and seemingly random type of eye movement, can be influenced by prior knowledge of the expected visual target, suggesting a surprising level of cognitive control over the eyes. The study adds to the scientific understanding of how vision is controlled and directed by cognitive processes. The findings could lead to better insights into the neuroscience of vision and visual disorders, which may sometimes have a motor component too.
