In neuroanatomy, the paracentral lobule is on the medial surface of the cerebral hemisphere and is the continuation of the precentral and postcentral gyri.The paracentral lobule controls motor and sensory innervations of the contralateral lower extremity.
In guenon Brodmann area 5 is a subdivision of the parietal lobe defined on the basis of cytoarchitecture.It occupies primarily the superior parietal lobule. Brodmann-1909 considered it topologically and cytoarchitecturally homologous to the preparietal area 5 of the human.
The posterior cingulate cortex (Brodmann's area 23) sends projections to dorsolateral prefrontal cortex (Brodmann's area 9), anterior prefrontal cortex (Brodmann's area 10), orbitofrontal cortex (Brodmanns’ area 11), the parahippocampal gyrus, posterior part of the inferior parietal lobule, the presubiculum, the superior temporal sulcus and ...
It is located on the anterior paracentral lobule on the medial surface. 2. The premotor cortex is responsible for some aspects of motor control, possibly including the preparation for movement, the sensory guidance of movement, the spatial guidance of reaching, or the direct control of some movements with an emphasis on control of proximal and ...
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. fMRI Research upon humans finds a connection with the caudalmost part of ...
Medially, it is contiguous with the paracentral lobule. The internal pyramidal layer (layer V) of the precentral cortex contains giant (70-100 micrometers) pyramidal neurons called Betz cells, which send long axons to the contralateral motor nuclei of the cranial nerves and to the lower motor neurons in the ventral horn of the spinal cord.

an imaginary line drawn from the preoccipital notch to the lateral sulcus posteriorly. The superior temporal gyrus contains several important structures of the brain, including: Brodmann areas 41 and 42, marking the location of the auditory cortex, the cortical region responsible for the sensation of sound;
