In which region can the central sulcus be located?

The central sulcus is a prominent landmark in the brain, serving as a key division between the frontal and parietal lobes. It is primarily situated within the regions known as G4-5, which correspond to the areas of the brain involved in motor and sensory functions. Specifically, G4 refers to the primary motor cortex, while G5 is associated with the primary somatosensory cortex. This anatomical relationship highlights the significance of the central sulcus in delineating areas responsible for motor control and sensory perception.

In addition, the central sulcus defines the border between these two crucial functional regions, facilitating an understanding of how the brain processes motor outputs and sensory inputs. This anatomical placement helps reinforce the connectivity between these areas, contributing to effective communication within the brain's operational framework.

The other regions mentioned do not accurately represent where the central sulcus is found, as they do not encompass the primary motor and sensory cortex directly adjacent to the central sulcus. This further emphasizes the importance of identifying the correct location in understanding neuroanatomy and its associated functions.
