title: Measurement of the effects of drugs on activity of permanent groups of rats.
abstract: The diurnal light-dark cycle, grouping of animals and spatial organization of the environment may affect the behavioral responses of animals to psychoactive drugs. A method of working with these factors experimentally is described, using a residential maze equipped with photocells for recording activity of groups of animals. Preliminary results show reliable activity measurements are produced which are sensitive to modification by drugs.
