The cerebral cortex is the outermost layer of the vertebrate brain. It is most highly developed in humans, and is the source of much of the thought and behavior uniquely attributed to man. It is functionally modular and is divided into four distinct regions. These are labeled based on the cranial bones that overlay them as the: frontal lobe, parietal lobe, temporal lobe, and occipital lobe. The cerebral cortex is predominantly gray matter.
