  2. Paracentral lobule - Wikipedia

    en.wikipedia.org/wiki/Paracentral_lobule

    The anterior portion of the paracentral lobule is part of the frontal lobe and contains a little portion of Brodmann's area 6 (SMA): this is because the paracentral sulcus (branch of the cingulate sulcus) does not correspond to the precentral sulcus on the medial plane.

  3. Precuneus - Wikipedia

    en.wikipedia.org/wiki/Precuneus

    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 ...

  4. Marginal sulcus - Wikipedia

    en.wikipedia.org/wiki/Marginal_sulcus

    It separates the paracentral lobule anteriorly and the precuneus posteriorly. Additional images. Position of marginal sulcus (shown in red).

  5. Sulcus (neuroanatomy) - Wikipedia

    en.wikipedia.org/wiki/Sulcus_(neuroanatomy)

    In neuroanatomy, a sulcus (Latin: "furrow"; pl.: sulci) is a shallow depression or groove in the cerebral cortex.One or more sulci surround a gyrus (pl. gyri), a ridge on the surface of the cortex, creating the characteristic folded appearance of the brain in humans and most other mammals.

  6. Paracentral sulcus - Wikipedia

    en.wikipedia.org/wiki/Paracentral_sulcus

    The paracentral sulcus is a sulcus of the brain. It forms the paracentral lobule's anterior border. [1] It is part of the cingulate sulcus. Gallery

  7. Precentral gyrus - Wikipedia

    en.wikipedia.org/wiki/Precentral_gyrus

    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.

  8. Inferior parietal lobule - Wikipedia

    en.wikipedia.org/wiki/Inferior_parietal_lobule

    The inferior parietal lobule (subparietal district) lies below the horizontal portion of the intraparietal sulcus, and behind the lower part of the postcentral sulcus. Also known as Geschwind's territory after Norman Geschwind , an American neurologist , who in the early 1960s recognised its importance. [ 1 ]

  9. Parieto-occipital sulcus - Wikipedia

    en.wikipedia.org/wiki/Parieto-occipital_sulcus

    In neuroanatomy, the parieto-occipital sulcus (also called the parieto-occipital fissure) is a deep sulcus in the cerebral cortex that marks the boundary between the cuneus and precuneus, and also between the parietal and occipital lobes.
