电生理学已被证明对于记录神经活动是非常有价值的,而神经像素探针的发展极大地增加了记录的神经元的数量。这些探头通常被敏锐地植入,但在自由活动的动物身上无法进行急性记录,所记录的神经元也无法跨天追踪。为了研究导航、学习和记忆形成等关键行为,必须长期植入探头。理想的慢性植入物应该(1)允许对神经元进行数周的稳定记录;(2)允许在移植后重复使用探针;(3)足够轻,可以在小鼠身上使用。在这里,我们介绍‘阿波罗植入物’,这是一种开源的可编辑设备,符合这些标准,可容纳多达两个神经像素1.0或2.0探头。植入物包括一个固定在探头上并可回收的“有效载荷”模块,以及一个粘合在头骨上的“对接”模块。该设计是可调的,便于更改探头之间的距离、插入角度和插入深度。我们在八个实验室对头部固定的小鼠、自由活动的小鼠和自由活动的大鼠进行了测试。即使在重复植入相同的探针后,记录的神经元数量在几天内也是稳定的。阿波罗植入物为可重复使用的慢性神经像素记录提供了一种廉价、轻便和灵活的解决方案。
Electrophysiology has proven invaluable to record neural activity, and the development of Neuropixels probes dramatically increased the number of recorded neurons. These probes are often implanted acutely, but acute recordings cannot be performed in freely moving animals and the recorded neurons cannot be tracked across days. To study key behaviors such as navigation, learning, and memory formation, the probes must be implanted chronically. An ideal chronic implant should (1) allow stable recordings of neurons for weeks;(2) allow reuse of the probes after explantation;(3) be light enough for use in mice. Here, we present the ‘Apollo Implant’, an open-source and editable device that meets these criteria and accommodates up to two Neuropixels 1.0 or 2.0 probes. The implant comprises a ‘payload’module which is attached to the probe and is recoverable, and a ‘docking’module which is cemented to the skull. The design is adjustable, making it easy to change the distance between probes, the angle of insertion, and the depth of insertion. We tested the implant across eight labs in head-fixed mice, freely moving mice, and freely moving rats. The number of neurons recorded across days was stable, even after repeated implantations of the same probe. The Apollo implant provides an inexpensive, lightweight, and flexible solution for reusable chronic Neuropixels recordings.
