The human brain is one of the important organs in the human body. It is the most complex of all organs. The brain is an organ composed of billions of nerve cells. It has parts of the brain that have important functions1. It is important for researchers to have details about brain anatomy and function that contribute to brain diseases and brain damage. The brain receives information about the body surface and its changes inside the body through sensory nerve receptors.After the interpretation of this information, it sends messages for the functioning of the muscles and glands via motoric. The brain is the center of all conscious action. It has lobes with different functions. The brain manages all the functions of the body. It interprets the information coming to the brain from the inner body of the human and also from the environment in which he lives. As a result of the brain’s control and interpretation of information; the individual realizes himself/herself and perceives the world. The brain receives information about both the changes in the body surface and the events occurring in the body through sensory nerve receptors. The brain receives information through the senses. The brain processes and interprets the information it receives. The brain, cerebellum, brainstem, and spinal cord are parts of the central nervous system. 12 pairs of cranial nerves, 31 pairs of spinal nerves, neural networks and ganglia are the components of the peripheral. Whole brain; consists of the brain, cerebellum, and brain stem. The whole brain is called the Encephalon. The largest and most recognizable part of the entire brain is the cerebrum. On the outside of the brain is the cortex cerebri, which is the gray matter formed by nerve cells. On the inside, it consists of white matter formed by axons, which are nerve cell extensions. The cerebrum is divided into two hemispheres, left and right. Brain through some grooves and slits; It is divided into the frontal, temporal, parietal, and occipital lobes. Brain; It assumes roles that process thinking, learning, memory, language, emotion, movement and perception 2-4. As a result, in the most important organ, the brain; In order to achieve improvement, it is important to stay away from both the substance and the information and visuals that remind the use of the substance.
