Conditions
Brief summary
Hemispatial neglect is a disorder where the patient has difficulty attending to objects and information in the left side of space, which occurs following strokes to the right side of the brain. This project is designed to help us understand how optokinetic stimulation treats the symptoms of hemispatial neglect.
Interventions
DEVICEOKS
Optokinetic stimulation will be displayed on a see-through liquid crystal display lens placed in front of the subjects.
