The brain can be divided into 6 major areas: the frontal lobe, the parietal lobe, the occipital lobe, the temporal lobe, the cerebellum and the brainstem.
Each area has specialist jobs to do. For example the occipital lobe processes a lot of the visual information from your eyes, while the frontal lobe is in charge of attention and behaviour processes.
Even within each of these bigger lobes there are more and more specialised areas. For example within the occipital lobe (which we know is in charge of visual information) there are specialised areas that process movement, and others that process colour.
