In anatomy, a fissure (Latin fissura, plural fissurae) is a groove, natural division, deep furrow, elongated cleft, or tear in various parts of the body also generally called a sulcus, or in the brain a sulcus.
Brain gyri and sulci serve two very important functions: They increase the surface area of the cerebral cortex and they form brain divisions. Increasing the surface area of the brain allows more neurons to be packed into the cortex so that it can process more information.

Central sulcus (in red). also called the central fissure, the central sulcus is a prominent sulcus that runs down the middle of the lateral surface of the brain, separating the frontal lobe from the parietal lobe.
Though the brains' ridges and valleys — called gyri and sulci, respectively — look random, they're actually consistent across individuals, and even some species.
A gyrus (plural: gyri) is a ridge on the surface of the brain. Each ridge is surrounded by fissures known as sulci (singular: sulcus). Gyri are unique structures that have an important evolutionary function; they increase the surface area of the brain up to an impressive 2000 centimeters squared.
Gyrus: A convolution on the surface of a cerebral hemisphere caused by the infolding of the cerebral cortex. The gyri are bounded by crevices in the cortex called sulci.
gyrus (plural gyri or gyruses) (anatomy) A ridge or fold on the cerebral cortex.
The central nervous system is made up of two types of tissue: the grey matter and the white matter. The grey matter is mainly composed of neuronal cell bodies and unmyelinated axons. This tissue directs sensory (motor) stimuli to nerve cells in the central nervous system where synapses induce a response to the stimuli.
The cerebrum (right and left) is the upper, front portion of the brain and consists of two hemispheres, or halves. The two hemispheres are connected by the corpus callosum, which is a large bundle of nerve fibers.
The corpus callosum is the primary commissural region of the brain consisting of white matter tracts that connect the left and right cerebral hemispheres.
Structure and FunctionThe precentral gyrus is the anatomical location of the primary motor cortex, which is responsible for controlling voluntary motor movement on the body's contralateral side. The primary motor cortex is topographically organized and creates a somatotropic map.
The fusiform gyrus is a large region in the inferior temporal cortex that plays important roles in object and face recognition, and recognition of facial expressions is located in the fusiform face area (FFA), which is activated in imaging studies when parts of faces or pictures of facial expressions are presented to
Here are 4 tips that should help you perfect your pronunciation of 'aramaic':
- Break 'aramaic' down into sounds: [ARR] + [UH] + [MAY] + [IK] - say it out loud and exaggerate the sounds until you can consistently produce them.
- Record yourself saying 'aramaic' in full sentences, then watch yourself and listen.
The name is derived from the Biblical "Pool of Bethesda," which in Hebrew means "House of Kindness." Bethesda is an unincorporated area, and the United States Geological Survey defines it as having its center at 38° 58′50″N 77 ° 6′2″W.
