The brain resembles something along the lines of a cauliflower and there is no discernible relationship between what it looks like and what it does. From the outside, the brain is dominated by the two, huge, wrinkled hemispheres. The under part of the brain and the brain stem are mostly involved in subconscious activities. The basal ganglia part of the brain helps us make automatic movements that we hardly ever think about-like swinging our arms when we walk. Tuesday No computer ever made rivals the brain's complexity.
Computers can play chess or solve incredibly difficult mathematical problems.
In other words, computers don't display common sense. The body seems to recognize how crucial the brain is. The organ is housed in bone and cushioned in fluids to reduce shock. This special layer of cells sheaths the blood vessels and capillaries in the brain, providing a special barrier which prevents anything except very small molecules from passing out of the blood. Specific channels allow sugars and other nutrients to pass in while excluding impurities which may have been taken in with food or inhaled.
