Real-time analog acquisition of electrophysiological signals with Soma

Abstract

Soma is a high-density recording system for real-time acquisition and analysis of extracellular electrophysiological signals. Here I describe the design, implementation, and evaluation of the Soma Acquisition Board, an 8-channel low-latency amplifier for amplification and digitization of these signals. Design trade-offs are discussed, and the resulting analog performance is quantified.
