ObjectiveThe objective of this research is to develop technologies and methods towards realizing a miniature implantable many-channel wireless neural-recording device. The approach is to develop and assemble sub-systems that can be programmed by neuroscientists to investigate scientifically and medically relevant neurophysiology.Intellectual MeritThe proposed wireless neural recording system consists of scaleable sub-system components that can be configures to acquire a broad range of neural signals. Furthermore, it includes a digital-signal-processing architecture that performs on-chip spike detection and alignment steps in the digital domain, which are typically performed off-chip in software. The proposed system also must operate while being subject to varying electrode conditions (i.e., impedance and offset voltage) while dissipating no more than several milliwatts of power to avoid tissue heating and enable (future) methods of wireless power transfer.Broader ImpactThe broader impacts include of the proposed work include: (1) technological transformation of important fields of research in neuroscience and neurology, (2) updating and enhancing the technological capabilities and experience of doctoral students training to be brain researchers or neuroengineers, (3) the involvement of undergraduate engineering students from underrepresented groups, and (4) the general education of California high-school teachers and community-college instructors that participate in annual UCLA-sponsored continuing-education events during the summer.

本研究的目的是开发实现微型植入式多通道无线神经记录装置的技术和方法。 该方法是开发和组装的子系统，可以编程的神经科学家调查科学和医学相关的neuropsychology.Intellectual MeritThe建议的无线神经记录系统由可缩放的子系统组件，可以配置为获取广泛的神经信号。 此外，它还包括一个数字信号处理架构，可在数字域中执行片内尖峰检测和对齐步骤，这些步骤通常在片外软件中执行。 所提出的系统还必须在经受变化的电极条件（即，阻抗和偏移电压），同时消耗不超过几毫瓦的功率，以避免组织加热并实现（未来）无线功率传输方法。更广泛的影响拟议工作的更广泛的影响包括：（1）神经科学和神经病学重要研究领域的技术改造，（2）更新和提高博士生的技术能力和经验，培养他们成为大脑研究人员或神经工程师，（3）来自代表性不足群体的本科工程专业学生的参与，以及（4）加州高中教师和社区学院教师的通识教育，他们在夏季参加加州大学洛杉矶分校主办的年度继续教育活动。
