The end part of the corpus callosum, towards the cerebellum, is called the splenium. This is the thickest part, and overlaps the tela choroidea of the third ventricle and the midbrain, and ends in a thick, convex, free border. Splenium translates as "bandage" in Greek. The trunk of the corpus callosum lies between the splenium and the genu.
Agenesis of the corpus callosum (ACC) is a rare birth defect in which there is a complete or partial absence of the corpus callosum.It occurs when the development of the corpus callosum, the band of white matter connecting the two hemispheres in the brain, in the embryo is disrupted.
The patient had a lesion in the left occipital lobe, blocking sight in the right visual field , and in the splenium of the corpus callosum. Dejerine interpreted this case as a disconnection of the speech area in the left hemisphere from the right visual cortex.
Normally, a callus will form on any part of the skin exposed to excess friction over a long period of time. Activities that are known for causing calluses include (but are not limited to) construction work and craftwork, the arts, [3] food preparation, many sports and physical activities, [4] [5] and fashion choices like wearing high heels.
In neuroanatomy, the subparietal sulcus (Sulcus subparietalis) or suprasplenial sulcus is a sulcus, or crevice, on the medial surface of each cerebral hemisphere, above the splenium of the corpus callosum. It separates the precuneus from the posterior part of the cingulate gyrus. It is the posterior continuation of the cingulate sulcus.
The quadrigeminal cistern [1] (also cistern of great cerebral vein, [1] vein of Galen cistern, [2] superior cistern, [2] [3] Bichat's canal, [3] or peripineal cistern [2]) is a subarachnoid cistern situated between splenium of corpus callosum, and the superior surface of the cerebellum.
Corpus callosum. A corpus callosotomy (/ k ə ˈ l ɔː s (ə) t ə m iː /) is a palliative surgical procedure for the treatment of medically refractory epilepsy. [1] The procedure was first performed in 1940 by William P. van Wagenen. [2]
The indusium griseum is prolonged around the splenium of the corpus callosum as a delicate layer, the fasciolar gyrus, [2] which is continuous below with the surface of the dentate gyrus. [3] The indusium griseum and fasciolar gyrus are very small components of the limbic lobe , and are continuations of the hippocampal formation, forming an ...
