REGIONS OF THE BRAIN

Through evolution the cortex (brain) has become enlarged so that it sits on top of the subcortical structures. The fissures and sulci appear to divide the brain into geographically distinct regions. These are called 'lobes' and there are 4 of them;

1. Frontal
2. Temporal
3. Parietal

One lobe maybe more responsible for a certain function than another, the occipital lobes contain the 'primary visual cortex'; the temporal lobe contains the 'primary auditory cortex', which receives impulses from the ear. The lobes are named after the skull bone that they underlie.
