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 ...
The quadrigeminal cistern lies between the splenium of the corpus callosum (superiorly), the cerebellar vermis (inferiorly and posteriorly), [5] [6] and the tentorial margin. [6] It is just superior to the tectum of the mesencephalon (midbrain). [3] It lies medial to part of the medial occipital cortex. [6]
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
The total number of long range fibers within a cerebral hemisphere is 2% of the total number of cortico-cortical fibers (across cortical areas) and is roughly the same number as those that communicate between the two hemispheres in the brain's largest white tissue structure, the corpus callosum. [4]
