The study of how medications impact cellular function in the nervous system, as well as the neurological mechanisms by which they influence behavior, is known as neuropharmacology. Behavioral and molecular neuropharmacology are the two primary disciplines of neuropharmacology. The study of how drugs affect human behavior (neuropsychopharmacology) is a focus of behavioral neuropharmacology, as is the research of how drug dependency and addiction affect the human brain. The study of neurons and their neurochemical interactions is known as molecular neuropharmacology, and it aims to discover medications that improve neurological function.
Neurochemistry is the study of chemicals that control and influence the physiology of the nervous system, such as neurotransmitters and other compounds like psychopharmaceuticals and neuropeptides. Neurochemicals influence the function of neurons, synapses, and neural networks, according to this branch of neuroscience. Neurochemists study the biochemistry and biology of organic compounds found within the nervous system, also as their roles in neurological processes like cortical plasticity, neurogenesis, and differentiation.
