The activity of single neurons in precentral cortex of unanesthetized monkeys (Macaca mulatta) was conditioned by reinforcing high rates of neuronal discharge with delivery of a food pellet. Auditory or visual feedback of unit firing rates was usually provided in addition to food reinforcement. After several training sessions, monkeys could increase the activity of newly isolated cells by 50 to 500 percent above rates before reinforcement.
在未麻醉的猕猴（恒河猴）的中央前皮层中，单个神经元的活动通过在神经元放电频率较高时给予食物颗粒来进行条件调节。除了食物强化外，通常还会提供单位放电频率的听觉或视觉反馈。经过几次训练后，猴子能够使新分离细胞的活动比强化前的频率增加50%至500%。
