Rats were rewarded for signaling large and small sensory evoked components with appropriate bar presses. Most rats operantly generated large components and correctly signaled only these. Two rats correctly signaled successful and unsuccessful attempts to generate large waves. One rat discriminated component amplitudes without operantly attempting to generate specific wave types.
通过适当按压杠杆来标记大、小感觉诱发电位成分的大鼠会得到奖励。大多数大鼠通过操作产生大的成分，并且只对这些成分进行正确标记。两只大鼠正确标记了产生大波形的成功和不成功尝试。一只大鼠能够区分成分幅度，而没有通过操作尝试产生特定的波形类型。
