It is called the cortex and it is wrinkly.
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.
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.

The elevations on the surface of the cerebrum that resemble speed bumps are called gyri. They are the raised ridges on the brain's cortex that help increase surface area for more cognitive processing.
The valleys separating the convolutions on the surface of the cerebrum are called sulci. They play a role in increasing the surface area of the brain, allowing for more neural connections and processing power within a limited space.
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.

the cerebral cortex
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!
On the surface of the cerebrum.
The cerebrum is the largest part of the brain and is divided into two hemispheres. It has a wrinkled surface called the cerebral cortex, which is responsible for higher brain functions. The cerebrum also has four lobes: frontal, parietal, temporal, and occipital, each with specific functions.
