The cerebrum is divided into '''two cerebral hemispheres''' connected by a mass of white matter known as the '''corpus callosum''' . Each hemisphere is split into four lobes, these are the '''frontal''', '''parietal''', '''occipital''' and '''temporal''' lobes. The surface of each hemisphere is made up of grey matter known as the '''cerebral cortex''' and is folded to increase the surface area available within the skull. The cortex has roles with '''perception''', '''memory''', and all higher thought processes, including concentration. | The cerebrum is divided into '''two cerebral hemispheres''' connected by a mass of white matter known as the '''corpus callosum''' .
