It has two closely placed cerebral hemispheres separated by a longitudinal cerebral fissure.The cerebral hemispheres are attached inferiorly by a thick nerve band called corpus callosum. Superior surface is convex while the inferior surface is concave. Internally, each cerebral hemisphere has a fluid filled cavity called lateral ventricle.
