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.
It is secondary association cortex, making connections with numerous other brain regions. The region's name refers to its anatomical location immediately behind the splenium of the corpus callosum in primates, although in rodents it is located more
The indusium griseum is prolonged around the splenium of the corpus callosum as a delicate layer, the fasciolar gyrus, [3] which is continuous below with the surface of the dentate gyrus. [4] The indusium griseum and fasciolar gyrus are very small components of the limbic lobe , and are continuations of the hippocampal formation, forming an ...
The boomerang sign is a radiological finding observed on magnetic resonance imaging (MRI) of the brain, particularly in diffusion-weighted imaging (DWI) sequences. It refers to a characteristic boomerang-shaped area of restricted diffusion in the splenium of the corpus callosum due to cytotoxic edema. [1]
The corpus callosum is essential to the communication between the two hemispheres. [2] A recent study of individuals with agenesis of the corpus callosum suggests that the corpus callosum plays a vital role in problem solving strategies, verbal processing speed, and executive performance. Specifically, the absence of a fully developed corpus ...
Separating the anterior horns of the lateral ventricles is the septum pellucidum: a thin, triangular, vertical membrane which runs as a sheet from the corpus callosum down to the fornix. During the third month of fetal development, a space forms between two septal laminae, known as the cave of septum pellucidum (CSP), which is a marker for ...
The two superior colliculi are situated inferior/caudal to the pineal gland and the splenium of corpus callosum. They are overlapped by the pulvinar of the thalamus, and a medial geniculate nucleus of the thalamus is situated lateral to either superior colliculus. [ 9 ]
Dejerine in 1892 described specific symptoms resulting from a lesion to the corpus callosum that caused alexia without agraphia. 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 ...
