The largest part of the brain is the cerebrum, which is responsible for many higher brain functions. This includes sensory perception, voluntary muscle movements, reasoning, problem-solving, and language. The cerebrum is divided into two hemispheres and further into lobes, each with specialized functions. For example, the frontal lobe is involved in decision-making and planning, while the occipital lobe processes visual information. The cerebrum’s surface is characterized by folds (gyri) and grooves (sulci), which increase its surface area and the number of neurons. Overall, the cerebrum plays a crucial role in shaping human experience and behavior.
