The celeberrum, also known as the cerebrum, is the largest part of the brain, responsible for higher brain functions. It is involved in processing sensory information, controlling voluntary movements, and facilitating cognitive functions such as thinking, reasoning, and memory. The cerebrum is divided into two hemispheres and includes various lobes that specialize in different functions, such as the frontal lobe for decision-making and the occipital lobe for vision. Overall, it plays a crucial role in shaping our experiences and interactions with the world.
