Abstract
Neural biopotentials are electrical signals generated by the cells of the nervous system. Recording and monitoring the aggregate or individual behavior of neurons yields information about the brain and the peripheral nervous system frequently used in clinical and research settings. Many different modalities of recording neural biopotentials have been developed. These differ in spatial scale, temporal resolution, and purpose. In order to faithfully record and make use of these neural signals, we must understand the signal properties, the specific kind of electrodes required for measurement, and the most appropriate circuit architecture needed to amplify and process these signals. Continued developments in electrode materials, interface circuits, and embedded systems for neural interfaces with tailored instrumentation solutions at a range of spatial and temporal scales are driving advances toward future unprecedented medical therapies and neuroscience discoveries.
