Neuroscience is a scientific study of the nervous system. Usually, neuroscience has been seen considered as a branch of biology. Thus, it is now present an interdisciplinary science which collaborates with other fields like as chemistry, engineering, linguistics, mathematics, computer science, medicine or allied disciplines, physics, philosophy, and psychology. The term neurobiology is mainly used interchangeably with a term neuroscience, although the former usually refers to the biology of the nervous system, while the latter refers to the complete science of the nervous system.

The scope of neuroscience has broadened to include many different approaches used to study the molecular, developmental, structural, cellular, functional, computational, evolutionary and medical aspects of the nervous system. The techniques concerned by neuroscientists have also expanded enormously, from molecular and cellular study areas of individual nerve cells to imaging of sensory or motor tasks in the brain. In past theoretical advances in neuroscience have also been aided by the study of neural networks.
