The cerebral cortex, cerebellum, and diencephalon are all recognized as major parts of the brain, each with specific functions and structural significance. The cerebral cortex is responsible for higher brain functions such as thought and action, while the cerebellum coordinates movement and balance. The diencephalon plays a crucial role in sensory and motor signaling, as well as in regulating functions such as sleep and appetite.

The frontal lobe, however, is not one of the main parts of the brain; instead, it is a region within the cerebral cortex. The cerebral cortex itself is divided into several lobes, including the frontal lobe, parietal lobe, temporal lobe, and occipital lobe. Thus, the frontal lobe is a subcategory of the cerebral cortex rather than a standalone part of the brain.

Understanding the structure of the brain is essential for comprehending its functions and the relationships between different regions. Each of the recognized main parts contributes to the overall complexity of brain function, and differentiating between the overarching parts and the subdivisions helps clarify these roles.
