A special type of eye movement, rapid eye movement sleep, rapid eye movement, occurs during REM sleep. The eyes are the visual organs of the human body, and move using a system of Extraocular muscles, six muscles. The retina, a specialised type of tissue containing Photoreceptor cell, photoreceptors, senses light. These specialised cells convert light into electrochemical signals. These signals travel along the optic nerve fibers to the brain, where they are interpreted as vision in the visual cortex. Primates and many other vertebrates use three types of voluntary eye movement to track objects of interest: smooth pursuit, vergence shifts and saccades. These types of movements appear to be i ...
