Neuropharmacology is a branch of pharmacology that focuses on studying how drugs affect the nervous system and behavior. This field examines the interactions between chemicals and neurotransmitters in the brain and how they can influence various neurological and psychiatric disorders. Neuropharmacologists study the effects of drugs on the brain and behavior, and how these drugs can be used to treat conditions such as schizophrenia, depression, anxiety, and neurodegenerative diseases like Alzheimer's and Parkinson's. This research area is crucial in developing new medications and treatment strategies for neurological disorders.
