What is the advantange of the cerebrum of the brain being wrinkled?
The "wrinkles" of the brain increase the surface area of the brain.
The involutions are called sulci or fissures, and the bumps in-between these involutions are called gyri.
Most of your brain cells are within the gray matter of the brain & most of your gray matter is in the outer layer of the brain. Therefore, if you increase the surface area of your outer layer of the brain with sulci and gyri, it creates more cortex for our limited sized skulls. The cortex is the main wrinkled part of our brain, and is responsible for much of our conscious experience.
In "lower" mammals such as mice, the brain is smooth.
Stretched out an average human brain is about 2.5 square feet in size.
It increases the surface to volume ratio of the brain. This allows more cortex for our limited sized skulls.

The cerebrum is the largest part of the brain. Its wrinkled surface is called the cerebral cortex. It is the part of the brain that controls thought, memory and the senses. The cerebrum is divided into two parts - the right hemisphere, which controls the left side of the body; and the left hemisphere, which controls the right side of the body.
Forebrain, Midbrain, Hindbrain. The above terms relate to the developing vertebrate brain, but from a purely visual perspective, you could also say that the three parts of the brain are the Cerebrum, Cerebellum, and Brainstem, where the cerebrum is the 'main' wrinkled top part of the brain (divided into two hemispheres), and the cerebellum is the two somewhat flattened parts which hang under the rear of the brain, and the brainstem is the part that…
In the central nervous system the communicates with and coordinates what happens in other parts of the brain?
Though I think the more correct answer is Cerebellum. For Penn Foster students, in the book it is Cerebrum pg. 478 Cerebrum: "The cerebrum communicates with and coordinates the activities of the other parts of the brain." Though according to other sources, and according to two doctors I asked about this. Cerebrum is the part of the brain that handles logic, imagination, reasoning ect. And CEREBELLUM is the part of the brain that communicates with…
The cerebrum is the "thinking" part of the brain, involved with such processes as logic, recognition, interpretation, and speech. Damage to the cerebrum can affect many activities that involve perception, computation, and communication, such as connecting objects with their function, being able to solve math problems, and reading / writing / speaking coherently.
One answer is: Cerebrum, Cerebellum, Brainstem. Another is: Forebrain, Midbrain, Hindbrain. This answer is more technically correct, while the first is more what you could see if looking at a naked brain from the outside. The Cerebrum is the wrinkled 'top', 'main' part of the brain, divided in the middle into two hemispheres; the Cerebellum is the two somewhat flattened parts which hang under the back of the cerebrum; the Brainstem is the continuation of…
