Neuroscience involves brain, spinal cord and nerves. It is the scientific study of the nervous system; Cellular Neuroscience and Molecular neuroscience involves the study of neurons at a cellular and molecular level that combines physiology, anatomy, molecular biology, developmental biology, cytology, mathematical modeling and psychology to understand the fundamental and emergent properties of neurons and neural circuits. The scope of neuroscience include different approaches used to study the nervous system at the different scales and the techniques used by neuroscientists have expanded enormously, from molecular and cellular studies of individual neurons to imaging of sensory and motor tasks in the brain Computational Neuroscience assists as a theoretical method for investigating the function and mechanism of the nervous system.
