Doses of atropine, ineffective in themselves, markedly augmented the increases in rate observed after amphetamine as well as the duration of these increases. In a subsidiary series of experiments methyl atropine was found to be much less potent than atropine in augmenting the effects of amphetamine on responding.}, issn = {0022-3565}, URL = {https://jpet.aspetjournals.org/content/132/1/91}, eprint = {https://jpet.aspetjournals.org/content/132/1/91.full.pdf}, journal = {Journal of Pharmacology and Experimental Therapeutics} }
