Vision and Blindsight

A visual and blind feeling of conscious vision - receiving and interpreting optical signals from the environment and forming an image in their own mind - is a very complicated process. Somehow, the signal from the photoreceptor in the eye is converted into a conscious visual experience. In all aspects of vision, perhaps the most difficult thing we can scientifically understand is this concept of consciousness. For some reason, the brain interprets the light waves as affecting the retina so that we can visually understand the surroundings.

Those who are blind due to degeneration or visual cortical damage but still have functional eyes can actually have responsiveness to some degree of visual and visual stimulus but conscious You can not perceive it. Visually impaired people are often unaware that they respond to visual causes, but consciously only adapt their actions to stimuli. Hearing and hearing (adjective form: hearing) is a healthy sensation. Hearing is vibration. Mechanical receptors convert exercise into electrical nerve impulses located in the inner ear.

When it absorbs data, it unintentionally interprets, organizes, and creates a preliminary understanding. It puts each individual information into the context. Blindness is one of the most dramatic examples of unconscious perception. People who usually damage the visual area of ​​the brain due to stroke can not be consciously seen. But Beatrice de Gelder of the University of Tilburg asked a man who was injured like that to walk in a dirty corridor. He flew around obstacles to the opposite side while moving up and down the hall to deftly. As scientists load this "blind" shaped patient-shaped cards, they guess the shape of the card with amazing accuracy. Unconscious benefit when conscious gaze disappears

Blind men have been blinded in many experiments that are required to "capture" the direction and color of objects, but they are doing it in a very accurate way. This phenomenon may also be observed among people with normal eyesight and may refuse to "observe" certain events, but you can explain exactly what happened. .8 blind study is widely regarded as a source of important evidence that "sensory information that does not affect our consciousness may influence our behavior" 9
