TY - JOUR T1 - Addiction and the brain: the role of neurotransmitters in the cause and treatment of drug dependence JF - Canadian Medical Association Journal JO - CMAJ SP - 817 LP - 821 VL - 164 IS - 6 AU - Denise M.

Sellers Y1 - 2001/03/20 UR - http://www.cmaj.ca/content/164/6/817.abstract N2 - RECENT SCIENTIFIC ADVANCES HAVE LED to a greater understanding of the neurobiological processes that underlie drug abuse and addiction. These suggest that multiple neurotransmitter systems may play a key role in the development and expression of drug dependence. These advances in our knowledge promise not only to help us identify the underlying cause of drug abuse and dependence, but also to aid the development of effective treatment strategies. ER -
