Four Lobes Overview

Cerebrum is covered with bulges and grooves on its surface. Based on these formations,
the cerebrum is divided into the four lobes, using the anatomical system. The main and
the deepest groove is the longitudinal fissure that separates the cerebral hemispheres.
However, the division into the lobes is made overlooking this fissure, and thus each lobe
is spread on both the hemispheres. Due to this, we often speak of the four pairs of lobes.
These lobes are frontal lobes, parietal lobes, occipital lobes, and temporal lobes. The
names of the lobes are partly related to the overlying bones of the skull such as frontal
and occipital bones. In some naming systems, the limbic lobe and the insula, or central
lobe, are distinguished as separate from other lobes.
