What is the advantage of the cerebrum of the brain being wrinkled?

Answer 1

The 'wrinkles' are called gyri and sulci. The best explanation is that the more there is, the more interconnections there are and the more intelligent it is.

Another reason is that the brain would outgrow your head if it was not wrinkled it would outgrow your head.

Answer 2

It increases the surface to volume ratio of the brain. This allows 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.

Answer 3

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.

Answer 4

The ridges give the brain more surface area and this allows it to be more complicated than if it just had a smooth surface.

Answer 5

yes the brain has lots wrinkles in fact the more you have the higher IQ you have.
