Some Effects of Hallucinogenic Morning-Glory Seeds on the Behavior of Rats
Certain varieties of morning-glory seeds are recognized hallucinogenic agents for humans. A preliminary series of studies was conducted to examine whether these seeds affected the behavior of rats. The Experimental and Control conditions were i.p. injections of an infusion from the seeds or of distilled water, respectively. Both activity and discrimination measures were used. The data showed a clear reduction in activity level in all tests under experimental conditions. There was no evidence of difference between the groups in the acquisition of a perceptually based discriminative response.
