Neural interfaces that can both stimulate and record from the peripheral nervous system are an important component of future bioelectronic devices. However, despite a long history of neurostimulation, there has been relatively little success in the design of a chronically implantable device for recording from peripheral nerves. This fundamental road block must be overcome if the design of advanced implantable devices is to continue. In this paper, we demonstrate the effectiveness of one method: velocity selective recording, a method that has been proposed as a tool for online neural recording that does not require training. We present results and analysis from invivo recordings made on the right vagus nerve of pig using a multiple-electrode cuff as a chronically implantable recording array.
能够对周围神经系统进行刺激和记录的神经接口是未来生物电子设备的重要组成部分。然而，尽管神经刺激有着悠久的历史，但在设计用于记录周围神经信号的长期可植入设备方面，取得的成功相对较少。如果要继续推进先进可植入设备的设计，就必须克服这一基本障碍。在本文中，我们展示了一种方法的有效性：速度选择性记录，这是一种被提议作为无需训练的在线神经记录工具的方法。我们展示了使用多电极袖带作为长期可植入记录阵列，在猪的右迷走神经上进行的体内记录的结果和分析。
