Neuroscience, also known as Neuro Biology or Neural Science, is the study of how the nervous system grows its structure, and function in body. Neuroscientists focus on the brain and its impact on behaviour and cognitive functions. Not only is neuroscience concerned with the normal functioning of the nervous system, but also what happens to the nervous system when people have neurological, psychiatric and neurodevelopmental disorders. Neuroscientists typically cover numerous branches at the same time.
