The brain is divided into four main sections: the cerebral cortex, the limbic system, the cerebellum and the brain stem. The cerebral cortex is made up of four parts that control different aspects of human function. The frontal lobes are responsible for behavior, decision-making, problem-solving and planning. The parietal lobes are responsible for sensory information, processing space, size, and movement. The temporal lobes are responsible for memory, hearing, and language. Finally, the occipital lobes are responsible for processing visual information from the eyes.
