The surface of the brain has wrinkles. The sulci are the inner folds of the surface of the cerebrum, and the gyri are the "bumps" of the surface. These increase the surface area of the cerebrum.

Our cerebrum is covered by the cerebral cortex. The cerebral cortex has many crevasses, which increases the surface area. This is largely the reason our brains are able to contain billions of neurons!
the cerebral cortex
On the surface of the cerebrum.
The convolutions on the cerebrum's surface are called gyri and sulci. Gyri are the raised folds, while sulci are the grooves that separate them. These convolutions increase the surface area of the brain, allowing for more neurons to be packed within the limited space of the skull.
Sulcus....
This only applies to larger mammals. The cerebral cortex is folded into many gyri (ridges) and sulci (furrows), which has allowed the cortex to expand in surface area without taking up much greater volume.
gyri
The surface area of the cerebral cortex is increased by its folding into gyri and sulci. This folding allows for more neurons to be packed into a smaller space, increasing the brain's processing power without significantly increasing its size.
It is called the cortex and it is wrinkly.
surface area
The gyri and sulci in the cerebellum are less prominent and simpler compared to those in the cerebrum. Gyri in the cerebellum are called folia, and the sulci are shallower. Additionally, the cerebellum's surface area looks more uniform compared to the highly convoluted surface of the cerebrum.
