Neuropharmacology
Neuropharmacology is a branch of pharmacology investigating drug effects on the nervous system to develop therapeutic compounds for psychiatric and neurological diseases. Neuropharmacology emerged around five decades ago, initially with only four drugs that were available for nerve disorders: caffeine, morphine, nitrous oxide, and aspirin. Subsequently, many new drugs emerged in the next few years. We can study brain functioning by understanding how drugs work at the molecular level.
Neurochemistry
Neurochemistry explores the configuration, composition, and roles of neuro-chemical compounds with a dual nature that originates from and influences the nervous system. These chemicals include substances such as serotonin, dopamine, oxytocin, and various other neurotransmitters or modulators. Research in this domain significantly delves into endogenous compounds, particularly neurotransmitters, alongside molecular elements that are non-genetic in nature of the nervous system.
