Brain research, also known as neuroscience, is the scientific study of the brain and nervous system. Researchers in this field investigate the structure, functions, and behaviors of the brain, as well as how these factors are influenced by genetic, environmental, and developmental factors. Some common topics of study in brain research include cognition, memory, emotion, perception, and neurological disorders. Advances in brain research have important implications for understanding and treating various conditions such as Alzheimer's disease, Parkinson's disease, and mental health disorders.
