The cerebrum is the largest part of the brain, located at the front and top of the skull. It is responsible for a wide range of responsibilities, including conscious thoughts, speech, judgment, thinking, reasoning, problem-solving, emotions, learning, and processing sensory functions like vision, hearing, and touch. The cerebrum is divided into two hemispheres, which communicate with each other through a large structure of white matter and nerve pathways called the corpus callosum. The cerebrum works together with other parts of the brain, especially the cerebellum, to help with daily activities. The cerebellum is a small part of the brain located at the bottom of the organ near the back of the head, which processes and regulates signals between other parts of the brain and body, and is involved in coordinating functions of the body, such as walking.

In essence, the cerebrum is responsible for the brain functions that allow us to interact with our environment and make us who we are. It is essential for memory, reasoning, communication, and many other functions. The cerebrum is not the entire brain itself, as other structures such as the cerebellum and brainstem work alongside it to control the voluntary actions in the body.
