During four weeks rats were learned to visit consequently 4 baited arms in the 8-armed radial maze. Picamilone (nicotinoyl-GABA) in a dose of 10 mg/kg daily accelerated rats to reach 80% level of learning (to 20-28 trials). After picamilone injections rats obtained the maximal level of short-term memory as just 3-5 trials. Piracetam in a dose of 200 mg/kg daily exerted no effects on long-term and short-term memory of rats in the radial maze.
在四周时间里，让大鼠学会依次访问八臂放射状迷宫中的4个有诱饵的臂。每天给予10毫克/千克剂量的匹卡米隆（烟酰-GABA）可加速大鼠达到80%的学习水平（20-28次试验）。注射匹卡米隆后，大鼠仅在3-5次试验中就获得了短期记忆的最高水平。每天给予200毫克/千克剂量的吡拉西坦对放射状迷宫中大鼠的长期和短期记忆没有影响。
