The brain uses ~20% of available oxygen for normal function, making tight regulation of blood flow and oxygen delivery critical for survival . The role of the cerebrum is to coordinate and process sensory and motor functions required by the body, as well as to provide reasoning functions, process emotions, and contribute the unique personality traits that make each human being an individual. We will use labeled diagrams and lateral images of the brain (side views) to walk through each lobe of the cerebrum.  It performs vital functions, including providing nourishment, waste removal, and protection to the brain. The brain gives us self-awareness and the ability to speak and move in the world. Four Lobes of the Brain Cerebral Cortex: The cerebral cortex is composed of four lobes: frontal lobe, parietal lobe, temporal lobe, and occipital lobe. The cerebellum, which stands for 'little brain', is a hindbrain structure that controls balance, coordination, movement, and motor skills, and it is thought to be important in processing some types of memory. Cerebrospinal fluid (CSF) is an ultrafiltrate of plasma contained within the ventricles of the brain and the subarachnoid spaces of the cranium and spine. The cerebrum is divided in half to have a right and left hemisphere. 6. Functionally, it obtains information from your surroundings. These sulci help to divide the cerebrum into its four lobes. 7. Association between various sensations and movements are controlled by association areas, in the frontal lobe. The brain contains two hemispheres, the left and the right, connected by a bundle of nerve fibers called the corpus callosum. The cerebrum is the largest part of the brain, located superiorly and anteriorly in relation to the brainstem. functions of the cerebrum motor and sensory portions of the cortex central sulcus seperates precentral gyrus of the frontal lobe the primary motor cortex pyramidal cells neurons that take part in thought, perception, and decision making voluntary motor pathways known as the pyramidal system motor speech area broca's area, motor vocalization These lobes include the frontal lobes, parietal lobes .
