Abstract

This paper describes improvements to the technique of velocity selective recording (VSR) in which multiple neural signals are matched and summed to identify excited axon populations in terms of velocity. The signals are acquired using a multi-electrode cuff (MEC) which is now available as a component for use in implantable neuroprostheses. The improvements outlined in the paper involve the replacement of the digital signal processing stages of a standard delay-matched VSR system with analogue delay lines which promise significant savings in both size and power consumption. These are crucial metrics for an implanted device. Preliminary simulations are provided.
