Neurons in the pigeon nidopallium caudolaterale (NCL) are important for the maintenance of information across delays as long as 3 s. In the current study, we recorded neural activity from the avian NCL of 3 birds trained on a working memory task with three different delay lengths intermixed within a session. We found that when the birds are unable to predict the upcoming delay length there is no evidence that NCL cells engage in temporal coding. Furthermore, delay activity did not differ between correct and incorrect trials. Both findings have implications for the function of delay activity and its role in supporting working memory.

鸽子尾外侧巢皮质（NCL）中的神经元对于长达3秒的延迟期间信息的维持非常重要。在当前的研究中，我们记录了3只鸟的鸟类NCL的神经活动，这些鸟在一个工作记忆任务中接受训练，该任务在一个实验环节中混合了三种不同的延迟长度。我们发现，当鸟类无法预测即将到来的延迟长度时，没有证据表明NCL细胞参与时间编码。此外，正确和错误试验之间的延迟活动没有差异。这两个发现都对延迟活动的功能及其在支持工作记忆中的作用具有启示意义。（《心理学文摘数据库记录》（c）2019美国心理学会，保留所有权利）
