The brain is split into two equal halves and each of these halves is separated into four lobes based on their functions, these being frontal, parietal, occipital and temporal lobes. The frontal lobe is especially effective in rational processing, motor functions and sexual behaviour. In addition to this, it controls the behavior in socialization, memory and impulse (as in impulse buying). In other words it helps to plan and realize behavior. The parietal lobe is responsible for processing information gathered by the five senses. At the same time, it plays a role in understanding both numbers and objects. The occipital lobe, where the visual cortex is located, is the area which processes vision and understands what is being seen by the person. The temporal lobe plays an active role in memory. The dominant temporal lobe is active in attributing meanings to words and object names. Information related to visual memory is also processed in the temporal lobe.
