central sulcus

a deep groove in the brain that separates the frontal and parietal lobes

The central sulcus, or sulcus centralis, is a prominent anatomical feature of the brain. It is a deep groove that divides the frontal and parietal lobes. It is highly significant in the context of brain function, as it delineates the primary motor cortex in the frontal lobe and the primary somatosensory cortex in the parietal lobe. This structural division helps to organize and control motor movements and sensory perception in the human brain.
