Neuropharmacology divulges on understanding the effects of chemical agents with neurobiological processes of the nervous system. The study involves various aspects of thenervous system interrogating single neurons to the whole region of the brain and spinal cord. Experiments are carried out on Mammalian, non-mammalian and invertebrates organisms to obtain novel insights on neurobiological mechanisms. In order to design a drug for a neurological disorder, one must understand how neurons communicate with each other. Theneuropharmacology market can be categorized on the basis of technology, application, and region.
