Perceptual adaptation

Perceptual adaptation is a unique function of the brain that accounts for the differences viewed in the world, as it relates to the senses. This phenomenon occurs in all senses, including vision, hearing, touch, and smell. An example is when images sensed through the eyes are relayed to the visual cortex of the brain, and if vision is altered slightly, the brain accounts for the difference and will allow one to perceive the world as "normal." This is a compensation mechanism the brain uses for the world to appear normal in our minds when our world has obviously been altered from its regular state. This is an important aspect in potential alterations to the visual field, effectiveness in compensating for alterations in the visual field, visual adaptation, and face recognition.
