The term CEREBRAL BRAIN LAYER is referring to the CORTEX, which is a six-letter word. The CORTEX is the outermost LAYER of the BRAIN and is responsible for higher-level functions such as sensory perception, motor commands, spatial reasoning, conscious thought, and language. It is divided into four distinct regions: the frontal lobe, parietal lobe, temporal lobe, and occipital lobe. Each of these lobes is responsible for different functions, such as memory, language, and emotion. The CORTEX is also responsible for integrating information from other parts of the BRAIN and body, allowing us to make decisions and act on them.
