This study investigates visuospatial deficits in patients who have experienced a unilateral stroke. Visuospatial deficits affect a person's ability to understand and interact with their environment visually. The researchers will study how patients' eye movements while looking at natural scenes relate to their cognitive, motor, and functional abilities, as determined by standard neuropsychological tests. Additionally, brain scans will be used to explore the relationship between brain structure and function and the patients' eye movement patterns.

Participants will be randomly assigned to receive either standard rehabilitation or an additional new training focusing on visual exploration. This training involves looking at natural scenes while receiving feedback through sounds that guide their attention to important areas of the image. The study will compare changes in the participants' eye movement behavior, cognitive tests, and brain scans with those in a control group and a group of healthy individuals.

• Who can participate: Participants must have had a first unifocal ischemic or hemorrhagic stroke. They should be vigilant and may have up to two small, clinically silent brain lesions. Symptoms must be evident in visual, attention, memory, motor, or language areas.
• Study details: Participants will undergo either standard rehabilitation or additional investigational visual exploration training. The training uses an auditory feedback system to guide eye movements toward important areas of images. A placebo is not involved in this study.
