What is the name of the deep fissure that seperates the two cerebral hemispheres?
By means of a prominent groove, called the longitudinal fissure, the brain is dividid into two halves called hemispheres. At the base of this fissure lies a thick bundle of nerve fibers, called the corpus callosum, which provides a communication link between the hemispheres. Left and right hemispheres. By means of a prominent groove, called the longitudinal fissure, the brain is dividid into two halves called hemispheres. At the base of this fissure lies a thick bundle of nerve fibers, called the corpus callosum, which provides a communication link between the hemispheres. The two cerebral hemispheres are divided by a deep longitudinal fissure and are connected medially at the bottom of the fissure by the corpus callosum. Prominent grooves, subdividing each hemisphere into four major lobes, are the central sulcus, the lateral fissure, and the parietooccipital fissure. The central sulcus and the lateral sulcus, divide each cerebral hemisphere into four sections, called lobes (see Division of the Cortex Into Lobes). The central sulcus, also called fissure of Rolando, also separates the cortical motor area (which is anterior to the fissure). By means of a prominent groove, called the longitudinal fissure, the brain is dividid into two halves called hemispheres. hippocampal fissure one extending from the splenium of the corpus callosum almost to the tip of the temporal lobe; called also hippocampal sulcus. longitudinal fissure the deep fissure between the two cerebral hemispheres. As viewed from above, the most prominent parts of the brain are the cerebral hemispheres, which are separated by the interhemispheric fissure (= longitudinal fissure) (#8431). The hemispheres consist of a superficial sheet of gray matter that is thrown into folds. 2. the transverse cerebral fissure between the diencephalon and the cerebral hemispheres; called also fissure of Bichat. zygal fissure any of the fissures on the cerebral cortex that consist of two branches connected by a stem. The two cerebral hemispheres are divided by a deep longitudinal fissure and are connected medially at the bottom of the fissure by the corpus callosum. The hemispheres consist of a superficial sheet of gray matter that is thrown into folds. The surface irregularities of the cerebrum are the sulci and gyri (#51113). A gyrus is the elevated portion between two sulci (furrows).
