Fortunately, the human brain is able to continuously create new pathways and neurological connections (synapses) throughout our lives, referred to as neuroplasticity. When the visual system is not working properly, providing incorrect information to other somatosensory systems, it can dramatically interfere with our quality of life. Our vision is such a powerful sense that it can override information from the other senses, which is sometimes beneficial and other times detrimental. When our eyes are open, two-thirds of the electrical activity of the brain is devoted to vision (Fixot). It is generally thought that between half and two-thirds of the brain is used for visual processing. However, as soon as we develop the necessary visual skills, vision begins to guide balance. When we are young, movement guides vision. It is this system that guides our balance, which in turn guides the development of our vision during our first years. The intimate relationship between the balance (vestibular/inner ear) and vision begins at birth, as the vestibular system is the only fully myelinated (a protective sheath around the nerve allowing the nerve impulse to move more quickly) and functioning system that we are born with (Tecklin). A deficiency in any of these three vitals systems can have a dramatic impact on the person’s ability to exist in their world. To maintain balance and navigate space in our physical world, we must organize and integrate information from the visual (eyes), proprioceptive (information perceived through our muscles and joints to tell us where we are in space) and vestibular (inner ears sensing motion, equilibrium and spatial awareness) systems. Vision is also connected to our balance system. In reality, the impact of vision on our lives is much more profound than just the clarity of the images being perceived. Balance, vision & Hearing Working Togetherįor most of us, vision is a term used to describe how clear things are.
