# Instrument Description The document describes the brain, specifically the cerebrum (Cerebellum). ## Cerebrum The cerebrum is the largest and most prominent part of the brain, occupying a significant portion of the skull. Its outer surface is characterized by grooves called sulci and ridges known as gyri. Primary sulci include the lateral (Sylvian) and central (Rolando) sulci. These sulci divide the cerebrum into lobes (frontal, parietal, temporal, and occipital). A further lobe, the insula, is located within the lateral sulcus. ## Other Brain Structures The document also mentions other important brain structures: * **Corpus Callosum:** A large band of white matter connecting the two cerebral hemispheres. * **Basal Nuclei:** Clusters of nuclei (e.g., lentiform nucleus, caudate nucleus, amygdala, claustrum) located deep within the cerebral hemispheres. * **Ventricles:** Hollow spaces within the brain filled with cerebrospinal fluid. * **Lobes and Cortical Areas:** Specific cortical areas are assigned to different functions, such as motor function (frontal lobe), sensory input (parietal lobe), auditory processing (temporal lobe), visual processing (occipital lobe), gustatory (taste), olfactory (smell) and other sensory functions. The document outlines the general organization and function of various cerebral structures, suggesting a broad overview of brain anatomy and cortical mapping.
