我们记录了4只鸟的羽状突神经元，鸟类相当于哺乳动物的前额皮质。这些鸟被要求啄一个刺激物，这个刺激物表明在一定的延迟（短或长）后，它们将得到的奖励（小或大）。我们发现，在奖励量和奖励延迟的基础上，将会收到的奖励的价值调节了栉水母神经元的活动。我们发现，价值编码在呈现样本期间最为突出，而在延迟期间和呈现奖励本身期间则不那么突出。我们的研究结果支持了这样一种观点，即在奖励数量和奖励延迟的基础上，阴草的活动反映了奖励价值的编码。
We recorded from neurons in the nidopallium caudolaterale, the avian equivalent of the mammalian prefrontal cortex, in four birds. The birds were required to peck a stimulus that indicated the amount of reward they would receive (small or large) after a certain delay (short or long). We found that the activity of neurons in the nidopallium caudolaterale was modulated by the value of the reward that would be received based on the reward amount and the delay to reward. We found that value coding was most prominent during the presentation of the sample period, and less so during the delay period and during the presentation of the reward itself. Our findings support the view that activity in nidopallium caudolaterale reflects the encoding of the value of reward based on a combination of reward amount and delay to a reward.
