The postrior portion of the corpus callosum is called thesplenium; theanteriois called thegenu(or "knee"); between the two is the "body", of the corpus callosum.
genu : forceps minor : connect medial and lateral surfaces of the frontal lobes
rostrum : connecting the orbital surfaces of the frontal lobes
trunk (body) : pass through the corona radiata to the surfaces of the hemispheres
trunk and splenium : tapetum : extends along the lateral surface of the occipital and temporal horns of the lateral ventricle
splenium : forceps major : connect the occipital lobes
|The corpus callosum is a large bundle of axons that connects the right and left cerebral hemispheres. The axons are | |processes of pyramidal cells in the cerebral cortex, and they carry information, in the form of patterns of nerve | |impulses, from cells of one hemisphere to cells in the contralateral hemisphere. The cell bodies of the axons in the | |corpus callosum are found mostly in the second and third layers (the Outer Granular Layer and the Outer Pyramidal Layer, | |respectively) of the cerebral cortex. Coordinated activity of the two hemispheres, and the unity of the brain itself, | |depend on the adequate functioning of the axons in the corpus callosum. | | | |Connections between the right and left halves of the brain are called Commissural Connections. The corpus callosum is the | |largest of the commissural connecting bundles. The axons in the corpus callosum are coated with myelin, a fatty substance | |that...
