Successful laboratory proof-of-concept experiments with neural prosthetic systems motivate continued algorithm and hardware development. For these efforts to move beyond traditional fixed laboratory setups, new tools are needed to enable broadband, multi-channel, long duration neural recording from freely behaving primates. In this paper we present a dual-channel, battery powered, neural recording system with integrated 3-axis accelerometer for use with chronically implanted electrode arrays. The recording system, called HermesB, is self-contained, autonomous, programmable and capable of recording broadband neural and head acceleration data to a removable compact flash card for up to 48 hours.
神经假体系统成功的实验室概念验证实验推动了算法和硬件的持续发展。为了使这些努力超越传统的固定实验室设置，需要新的工具来实现对自由活动的灵长类动物进行宽带、多通道、长时间的神经记录。在本文中，我们展示了一种双通道、电池供电的神经记录系统，该系统集成了3轴加速度计，用于与长期植入的电极阵列配合使用。该记录系统名为HermesB，它自成一体、自主运行、可编程，并且能够将宽带神经和头部加速度数据记录到可移动的紧凑型闪存卡中，记录时间长达48小时。
