Velocity Selective Recording: A Demonstration of Effectiveness on the Vagus Nerve in Pig

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 in-vivo recordings made on the right vagus nerve of pig using a multiple-electrode cuff as a chronically implantable recording array.
