Research in my laboratory centers on the study of psychoactive drugs with special emphasis on nootropics and drugs of abuse.
In collaboration with Dr. Richard Rabin of this department, behavioral data are correlated with biochemical indices of drug action in an attempt to understand at the receptor level the effects in intact animals of psychoactive drugs. Behavioral data are obtained using the techniques of operant behavior with special emphasis on the phenomenon of drug-induced stimulus control. Current interests include the serotonergic basis for the actions of indoleamine and phenethylamine hallucinogens including LSD and [-]-DOM as well as their interactions with selective monoamine reuptake inhibitors such as fluoxetine [Prozac]. In the area of nootropics, recent studies have examined the effects of EGb 761, an extract of Ginkgo biloba; for these investigations, a delayed non-matching to position task in a radial
maze is employed. Currently, studies are in progress to assess the serotonergic basis for the cognitive effects of drugs of abuse including LSD and MDMA [Ecstasy].
Behavioral pharmacology of psychoactive drugs, including psychotherapeutic agents and drugs of abuse; mechanisms of action of hallucinogens.
Research in Dr. Jerrold Winter‘s laboratory seeks to understand the ways in which drugs alter behavior. Many chemicals are candidates for study but attention in the last few years has centered on hallucinogens such as LSD, phencyclidine, DOM, and ibogaine. Another area of major interest is age-related memory impairment and those natural materials,
including ginseng and gingko biloba, which are purported to influence that impairment. The behavioral effects of these drugs are studied in rats trained with the techniques of operant conditioning. Specific variables in use at the present time include drug-induced stimulus control, radial maze acquisition and performance, and conditioned place preference and
In addition, Dr. Winter actively collaborates with Dr. Richard Rabin of the Department of Pharmacology and Toxicology in order to correlate behavioral effects with biochemical indices of action at the receptor level and with functional efficacies in second messenger systems.
