Cerebral cortexOuter layer of the cerebrum of the mammalian brainThe cerebral cortex, also known as the cerebral mantle, is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals. It is the largest site of neural integration in the central nervous system, and plays a key role in attention, perception, awareness, thought, memory, language, and consciousness.
Francesco GennariFrancesco Gennari (born 4 October 1750 di Langhirano; died 4 December 1797) was an Italian anatomist. He is known for line of Gennari, a macroscopically white band seen in the cerebral cortex of the occipital lobe, which he observed on 2 February 1776 in the course of examining ice-frozen sections of unstained human brain during his study in medical school.
Occipital lobeThe occipital lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The name derives from its position at the back of the head, from the Latin ob, 'behind', and caput, 'head'. The occipital lobe is the visual processing center of the mammalianbrain, containing most of the anatomical region of the visual cortex. The primary visual cortex is Brodmann area 17, commonly called V1 (visual one).
Band of BaillargerThe bands of Baillarger, in neuroanatomy, are two myeloarchitectural structures, the external band of Baillarger and the internal band of Baillarger. These are myelinated fibers that course in the internal granular layer (layer IV) and internal pyramidal layer (layer V), respectively, of cerebral cortex. In the primary visual cortex (V1), the external band of Baillarger is enlarged and is called the line of Gennari. They are named after Jules Baillarger.
Grey matterGrey matter (gray matter in American English) is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and unmyelinated axons), glial cells (astrocytes and oligodendrocytes), synapses, and capillaries.
ThalamusThe thalamus (pl.: thalami; from Greek , "chamber") is a large mass of gray matter on the lateral wall of the third ventricle forming the part of the diencephalon (a division of the forebrain). Nerve fibers project out of the thalamus to the cerebral cortex in all directions, known as the thalamocortical radiations, allowing hub-like exchanges of information.
PrimateOrder of mammalsPrimates is an order of mammals, which is further divided into the strepsirrhines, which include lemurs, galagos, and lorisids; and the haplorhines, which include tarsiers and simians (monkeys and apes).
Visual cortexIn mammals, the visual cortex of the brain is the area of the cerebral cortex that processes visual information. The visual cortex is located in the occipital lobe, located at the rear of the head. Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex.
AxonAn axon (from Ancient Greek: ἄξων, romanized: áxōn, lit. 'axis'; also called a nerve fiber or fibre) is a long slender projection of a nerve cell or neuron found in most animals that typically conducts electrical impulses known as action potentials away from the nerve cell body. The function of the axon is to transmit information to different neurons, muscles, and glands.
MyelinMyelin ( ) is a lipid-rich material that in most vertebrates surrounds the axons of neurons to insulate them and increase the rate at which electrical impulses (called action potentials) pass along the axon. The myelinated axon can be likened to an electrical wire (the axon) with insulating material (myelin) around it. However, unlike the plastic covering on an electrical wire, myelin does not form a single long sheath over the entire length of the axon.
Calcarine sulcusThe calcarine sulcus (or calcarine fissure) is an anatomical landmark located at the caudal end of the medial surface of the brain of humans and other primates. Its name comes from the Latin "calcar" meaning "spur". It is very deep, and known as a complete sulcus. StructureThe calcarine sulcus begins near the occipital pole in two converging rami. It runs forward to a point a little below the splenium of the corpus callosum.University of ParmaThe University of Parma (Italian: Università degli Studi di Parma, UNIPR) is a public university located in Parma, Emilia-Romagna, Italy. Organized into nine departments, it is one of the oldest universities in the world. As of 2016, it had approximately 26,000 students.*As an Amazon Associate I earn from qualifying purchases.
