Nootropyl (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 3x4 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.
脑复康（吡拉西坦）是一种据报道能促进动物学习的药物，通过将其给予正常志愿者来测试其对人类的影响。在一项双盲研究中，受试者每天服用3次，每次4粒，每粒400毫克。每个受试者学习呈现在记忆鼓上作为刺激的一系列单词。7天后未观察到效果，但14天后言语学习显著增加。
