paracentral lobule

The more medial part of the superior frontal gyrus is distinguished as the paracentral lobule.

It forms the paracentral lobule's anterior border.

(Trends in Neuroscience) It is located above the cingulate sulcus inside the anterior paracentral lobule.

The anterior portion of the paracentral lobule is part of the frontal lobe and is often referred to as the supplementary motor area.

The marginal sulcus is the portion of the cingulate sulcus adjacent to the paracentral lobule and the precuneus.

The axons synapse in the primary sensory cortex, with lower body sensation most medial (e.g., the paracentral lobule) and upper body more lateral.

The core comprises portions of the posterior cingulate cortex, the precuneus, the cuneus, the paracentral lobule, the isthmus of the cingulate, the banks of the superior temporal sulcus, and the inferior and superior parietal cortex, all located in both cerebral hemispheres.

Sensorimotor Anterior Region This occurs around the margin of the cingulate sulcus (blue in figure) and is connected with sensorimotor areas of the cerebral cortex such as the paracentral lobule, supplementary motor area, premotor cortex, somatosensory area (Brodmann area 2), parietal operculum and insula.
