The corpus callosum is divided into four parts: rostrum, genu, body/trunk and splenium. The posterior portion of the corpus callosum is called the splenium; the anterior is called the genu (or "knee"); between the two is the truncus, or "body", of the corpus callosum. The corpus callosum (CC) comprises axons connecting the cortices of the two cerebral hemispheres and is the principal white matter fiber bundle in the brain. It spans part of the longitudinal fissure, connecting the left and right cerebral hemispheres, enabling communication between them. The six elephants studied herein had the largest absolute corpus callosums recorded to date; however, relative to the mass of their brain, the size of the corpus callosum was what would be expected of a typical eutherian mammal with a brain mass of approximately 5000 g. The data for elephants hinted at sexual dimorphism in size of the corpus callosum, with female elephants having … The posterior portion of the corpus callosum is called the splenium; the anterior is called the genu (or "knee"); between the two is the truncus, or "body", of the corpus callosum. It is divided into four parts (from anterior to posterior): rostrum 9 The corpus callosum is the largest collection of white matter within the brain, and it has a high myelin content. It is a compact structure that acts as a “bridge” between the hemispheres of the brain, and is located at the bottom of the interhemispheric fissure and over the septum pellucidum and the lateral ventricles. ; The genu is the bend of the anterior corpus callosum and the forceps minor is a tract that projects fibres from the genu to connect the medial and lateral surfaces of the frontal lobes. (1937) Agenesis of the corpus callosum. (1890) On the absence of the corpus callosum in the human brain with a description of a new case. Corpus callosum, bundle of nerve fibres in the longitudinal fissure of the brain that enables corresponding regions of the left and right cerebral hemispheres to communicate. It connects the left and right sides of the brain, allowing for communication between both hemispheres.The corpus callosum transfers motor, sensory, and cognitive information between the brain hemispheres. Diagnosis by ventriclographic examination. Corpus Callosum, Thalamus, And Nerve Anatomy In this image, you will find corpus callosum, thalamus, optic nerve, optic tract, pineal gland, superior colliculus, infundibulum in it. The virtual tract maps obtained in vivo using this approach were faithful to the classical descriptions of white matter anatomy that have previously been documented in postmortem studies. Among these nuclei are the basolateral complex, the medial nucleus, the cortical nucleus, the central nucleus, and the intercalated cell clusters.
