The study of the nervous system and its disorders is called neuroscience. This interdisciplinary field examines the structure, function, and development of the nervous system, including the brain, spinal cord, and peripheral nerves. Neuroscience also explores various aspects of behavior, cognition, and neurological disorders such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis. By understanding the intricate workings of the nervous system, researchers aim to develop better treatments and interventions for these disorders and improve our overall understanding of human behavior and cognition.
