The human brain, which has a volume of approximately 1,350 and 1,500 cm, is made up of 6 cerebral lobes (regions into which the brain is divided, each with a series of linked functions). The first is sensation and perception, which integrates sensory information to develop a single perception (also known as cognition). It is very interrelated with the rest of the lobes, and acts in . The cerebral cortex contains three types of functional areas: motor areas, sensory areas, and association areas. The parietal lobe of the brain, also called the association cortex, is located parallel to the deep groove that divides the brain into right and left halves. Research suggests that, the more sensory input a region of the body provides, the more . The parietal lobe is a lobe in the brain. So, if a single word has to be chosen to define what the function of the parietal lobe is, this should be "integration", a concept that refers to the functions of many other parts of the brain.
