What is the name of the major sulcus that divides the frontal lobe from the parietal lobe?

The central sulcus is the key anatomical landmark that separates the frontal lobe from the parietal lobe in the brain. This prominent groove runs laterally across the cerebral hemispheres and is crucial for the organization of brain functions. The region anterior to the central sulcus is primarily associated with voluntary motor control, which is located in the frontal lobe. In contrast, the area posterior to the central sulcus is primarily involved in sensory processing, housed within the parietal lobe.

This anatomical division is significant not only in terms of physical structure but also regarding functional specialization, which plays a crucial role in understanding neuroanatomy and its implications for both psychological and neurological conditions. The central sulcus is, therefore, one of the most important sulci in neurology, often referenced in discussions around brain mapping and functional neuroimaging.
