Question

Quizplus · Accepted Answer

Paralysis of the extra-ocular muscles causes motion perception when eye movements are attempted because the inability to move the eyes creates a mismatch between the visual information received and the motor commands sent to the eye muscles, resulting in the sensation of motion even when there is none. This is known as the oculomotor hypothesis of motion perception.
