How does the hemisphere of the brain work?

The brain is the main organ of the human body that regulates all life processes. We have two cerebral hemispheres that are separated by a groove. Each lobe of the brain is responsible for its own processes. For example: the frontal lobe is responsible for thinking, memory, situation analysis, motivation, and more. The temporal lobes receive hearing. The hemispheres have convolutions. The more of them, the better the brain is developed. New convolutions can appear throughout life and their appearance is associated with brain activity. In addition to the hemispheres, there is also the cerebellum, pons, and other parts.
