Document Summary
Humans rely more on vision that any of sense. We gather light through our eyes and the visual processing occurs in our brain. Vision is a perceptual process of what happens in the brain. Light > photoreceptor photo activation > neural activity > awareness. Perceptual adaptation after a while, your brain adapts to the new incoming stimulus. Hemi spatial neglect damage to parietal lobe. You can see the left side of the world; they just do not pay attention to it. The only pay attention to the right side of the world. after damage to one hemisphere of the brain is sustained, a deficit in attention to and awareness of one side of space is observed. The rods are most sensitive to light and dark changes, shape and movement and contain only one type of light-sensitive pigment. Light must pass through all layers of the retina before reaching the photoreceptors.
