We introduce a straightforward, robust method for recording and analyzing spiking activity over timeframes longer than a single session, with primary application to the marmoset (Callithrix jacchus). Although in theory the marmoset's smooth brain allows for broad deployment of powerful tools in primate cortex, in practice marmosets do not typically engage in long experimental sessions akin to rhesus monkeys. This potentially limits their value for detailed, quantitative neurophysiological study. Here we describe chronically-implanted arrays with a 3D arrangement of electrodes yielding stable single and multi- unit responses, and an analytic method for creating "supersessions" combining that array data across multiple experiments. We could match units across different recording sessions over several weeks, demonstrating the feasibility of pooling data over sessions. This could be a key tool for extending the viability of marmosets for dissecting neural computations in primate cortex.

mos猴中电生理学“超级会话”的硬件/软件系统

我们引入了一种简单，健壮的方法来记录和分析比单个会话更长的时间范围内的尖峰活动，主要应用于the猴（Callithrix jacchus）。尽管从理论上讲，mar猴的平滑大脑可以在灵长类皮层中广泛部署强大的工具，但实际上mar猴通常不会进行类似于恒河猴的长时间实验。这可能限制了它们在详细的定量神经生理学研究中的价值。在这里，我们描述了带有电极的3D排列的长期植入的阵列，可产生稳定的单单元和多单元响应，以及一种用于创建“超级会话”的分析方法，该方法结合了跨多个实验的阵列数据。我们可以在几个星期内对不同录制时段的单元进行匹配，展示了在会话之间合并数据的可行性。这可能是扩展of猴生存能力的主要工具，用于剖析灵长类皮层中的神经计算。
