Four birds were trained on a delayed matching-to-sample task with common outcomes where correct responses during both red and green trials yielded reward. We recorded neuronal activity from the avian nidopallium caudolaterale, the avian equivalent of the mammalian prefrontal cortex, and the avian nidopallium frontolaterale, a higher-order visual processing region. In both regions we found sustained activity during the delay period of both red and green trials. These findings provide the first evidence that delay activity in the pigeon's nidopallium caudolaterale and nidopallium frontolaterale represent a neural correlate for the to-be-remembered sample stimulus.

鸽子的NCL和NFL神经元活性代表样品的神经相关性。

对四只家禽进行了延迟的配比采样任务培训，这些任务具有共同的结果，其中红色和绿色试验期间的正确反应会产生奖励。我们记录了禽类nidopallium caudolaterale（相当于哺乳动物前额叶皮层的禽类）和禽类nidopallium frontolaterale（一个较高阶的视觉处理区域）的神经元活动。在两个地区，我们都发现在红色和绿色试验的延迟期内持续活动。这些发现提供了第一个证据，即鸽子的鼻外侧pal和外侧外侧pal的延迟活动代表了要记忆的样本刺激的神经相关性。（PsycINFO数据库记录
