👉 The term "cerebrum" refers to the large part of the brain that houses the intellectual and sensory functions associated with the perception, memory, language, and decision-making. The cerebrum is divided into two main parts: the cerebral cortex, which contains the majority of the brain's white matter (which is responsible for processing information), and the cerebral hemispheres, which contain the black matter that makes up the left and right halves of the brain.
