A detailed description and evaluation of drugs that influence human behaviour. Although the greatest emphasis is upon the biochemical mechanisms and psychological effects of drugs used within clinical settings, all major pharmacological classes are covered. Since prediction of drug effects requires an understanding of chemical pathways and their location within the human brain, the student should have a basic understanding of chemistry and neuroanatomy.
