Figure 3. Principle of audiovisual stimulation (NeurofyResearch) program. Sequence of the visual task. (A) Eight yellow still spheres are present in a virtual cube. (B) One of these spheres turns red for 15 s (cued target) and returns yellow. (C) All spheres randomly move following linear paths across the visual field encompassing the blind field and bouncing on one another and on the walls of the virtual 3D cube when collisions occurred. (D) After 30 s, spheres stopped moving. (E) The patient had to select the cued target using a hand-guided laser pointer. (F) Correct selection was considered a positive hit.
