Essay on The Sophistication of the Brain - 1473 Words

To what extent is it true that the brain is a sophisticated information processor? The human brain is the most important part of the nervous system. The brain along with the spinal cord makes up the central nervous system and together they control all of the body’s important functions, such as motor functions, speech, vision, hearing and also involuntary functions like breathing. Many of these functions are localised to a specific area of the cerebrum. The cerebrum is split into four lobes; the frontal, parietal, temporal and occipital lobes, which are specialised to carry out their different roles. The cortex is divided into two hemispheres; the left hemisphere is associated with motor control, speech and language functions and logic;†¦show more content†¦They both transmit information by using electricity; however, the brain uses chemical messages as well as electrical impulses. A computer can process information much faster than the brain can; for example mathematical calculations can be carried out immediately on a computer rather than having to work out the answer logically like the brain would have to. However, the brain is capable of emotion, imagination and creativity, whereas a computer can only follow the instructions given to it. Another important comparison between the brain and a computer is the fact that the brain cannot be turned off unlike a computer. If any part of a computer gets damaged, it is easily replaceable. However, if an important part of the brain is in any way damaged, it can be difficult to regain normal function and near impossible to replace it. The brain is given the analogy of the hardware and software of a computer. The brain is seen as the hardware as it is the physical structure and the mind is viewed as the software. This is because software is not physical and somewhat controls what processes can be carried out on a computer. A computer has a hard disk which can store a large volume of information, which is similar to the long term memory store in the brain. Short term memory is stored in the brain, much like RAM in a computer (Lytton, 2002).
