Piracetam, a drug reported to facilitate learning in animals was tested for its effect on man by administering it to normal volunteers. The subjects were given 3×4 capsules at 400 mg per day, in a double blind study. Each subject learned series of words presented as stimuli upon a memory drum. No effects were observed after 7 days but after 14 days verbal learning had significantly increased.
