Brain and its lobes:
As mentioned earlier, the nervous is split into the CNS and
PNS. We will focus mostly on the CNS since it is composed of the brain (our
topic of discussion) and the spinal cord.
The brain is split into 4 lobes- the frontal, temporal, parietal and
occipital lobes. The lobes are made of and separated by sulci and gyri. The
lobes contain many different brain structures such as the thalamus and the
prefrontal cortex.
Questions regarding the brain structures:
What is the difference between sulci and gyri?
How many lobes does a brain have?

-4 lobes.
1-Gyrus(gyri)-is a ridge on the cerebral cortex. Folds on the brain material. Many ridges called convolutions, or gyri, or gyrus, separated by grooves, mark the cerebrum's surface.While Sulcus(sulci)-shallow grooves on the brain. Generally, a shallow to somewhat deep groove is called a sulcus, or sulci, and a very deep groove is called a fissure.
