Neuroscience deals with the study of the nervous system; this includes the brain, the spinal cord, and the neural circuits. This interdisciplinary field draws on domains as diverse as, anatomy and physiology, cellular and molecular biology, and human behavior and cognition, to tease out information regarding the workings of the brain, at resolutions previously unimagined. It drills down from macroscopic processes such as organization of large-scale cerebral systems to microscopic processes such as neurochemical signaling. Psychology is that branch of science that deals with the connection between the mind, mental processes, and behavior. It explores phenomenon, such as attention, perception, cognition, emotion, intelligence, brain functioning, and personality, while also exploring interpersonal relationships.
