Early research of the biopsychology has proved that cerebral cortex of human being constantly manages lots of information primarily received by our eyes and ears. However, contemporary research supplements the previous findings by stating that other sensory organs are also involved in the visual process of the human brain. According to neuroscientists, visual cortex is not just associated with information received by our eyes. A separate area of the brain is responsible for discrimination of spatial information. In short, the human brain is like a super computer that normally processes a vast amount of information within seconds perceived by our sensory organs. Processing then goes through information bank located in the brain. During this phase it looks for corresponding bits of information there.
Researchers of the National Academy of Sciences (2004) came up with an important finding: they discovered that the visual area of the brain normally processes information by directly referring to what has been received by our hearing and touch. Although a sensory cortex can process information from a single sense, there are also border regions in our brain. The neurons there can receive 10% input from two different senses. This testifies that auditory neurons process as much visual information as their counterparts - sensory neurons; and visual neurons can receive auditory information, as well as they receive sensory input. To reach the maximum potential, the human brain needs to use its power effectively.
Disorder of Selective Attention and Brain Damage
According to Dictionary of Optometry and Visual Science (2009), simultanagnosia is a person’s inability to recognize several elements within a simultaneous visual scene. A person, however, may perceive separate elements of it, except the whole visual display. Additionally, a person may have normal vision. The particular brain disorder can develop as a result of a lesion either in visual cortices or in temporal lobes. The disorder of selective attention is also associated with Balint’s syndrome, which is disease of the parietotemporal areas of the brain.
