The cerebral cortex has a folded structure due to the furrows in which 2/3 of its surface is hidden. Folding of the bark increases its area to 2000–2500 cm2. Each hemisphere of the cortex (left and right) with deep grooves (depressions) is divided into four lobes: frontal, parietal, temporal and occipital. The frontal lobe is separated from the parietal lobe by a deep central furrow. The lateral groove limits the temporal lobe.
