Neuroscience focuses on the relationships among brain function, information processing, and behavior. Researchers in this field come from widely disparate backgrounds, including cognitive psychology, clinical neuropsychology, neuroimaging, neurobiology, molecular biology, genetics, neuroethology, biopsychology, physiology, neurology, psychiatry, philosophy, and computer science. Thus, research questions are considered from many different levels, and many different converging methodologies are used.
