Vestibular System

“As we move and interact with gravity sensory receptors in the ear are activated, and impulses appraising the central nervous system about the positioning of the head in space are directed to various parts of the brain and down the spinal cord. It is believed that sensory impulses from the eyes, ears, muscles and joints must be matched to the vestibular input before such information can be reprocessed efficiently. If this is true, what we see, hear and feel makes sense only if the vestibular system is functioning adequately.” Pyter, J. Johnson, R. 1981

The vestibular system is the first sensory system to develop. It is visible at two months gestation and fully formed by the fifth month of gestation. It is one system that feeds input to the reticular activating part of the central nervous system, responsible for awareness it is sometimes referred to as the “wake up the brain system” allowing us to focus our attention. Electric stimulation of the Median Nerve also is used to wake up coma patients by stimulating the reticular system.

Neuro-Optometry Rehabilitation

The cerebellum contains more then 50 percent of the brains neurons!  The brain consumes 20 percent of the body’s oxygen.  Blood rushes to the cerebellum when a person prepares to perform a task.  Oxygen molecules pass from the blood, reaching the neurons with the help of glial cells that out number neurons 10 to 1.

The cerebellum of course, has a regulatory effect on eye movement.  The eyes have two types of functions, A. Image delivery from central visional function, and B. Peripheral or ambient vision.  The Lateral Geniculate Body connects the optic nerve with the occipital cortex, but it also relays visual information to parts of the brain other then the visual cortex.

Myofascial Release

by: Raymond H. Cralle

We all know that injuries induce the muscles to splint in order to support the area and protect it from further trauma.  Fibroblasts are stimulated to lay down more collagen fibers to prevent movement.  The inactivity of the splinted area causes the ground substance in the connective tissue to gel around the muscle fibers, which puts pressure on the capillaries, decreasing the oxygen supply to the muscle, and on the nerve endings, decreasing the efficiency of the neural signal.
