Human neuroscience, also known as Neural Science and Neurobiology is the scientific study of the nervous systems of the body and specifically the brain. However, while neurobiology looks at the biology of the nervous system, neuroscience refers to anything to do with the nervous system. In other words, it examines how the nervous system develops, its structure, and what it does. In the past, it was a subdivision of biology, but currently it is a multidisciplinary field that is also one the most rapidly advancing. This field of study combines physiology, psychology, anatomy, computer, biology (molecular and developmental), medicine, and cytology to investigate the fundamental and emergent properties of neurons and neural circuits by offering hypotheses and conceptualizations to examine cognition, learning, perception, behavior, and emotions.

The scope of neuroscience has broadened over time to include different approaches used to study the nervous system at different scales and the techniques used by neuroscientists have expanded enormously, from molecular and cellular studies of individual neurons to imaging of sensory, motor and cognitive tasks in the brain.
