I present a method for decreasing the duration of artifacts present during intra-cortical microstimulation (ICMS) recordings by using techniques developed for digital communications. I use a Zero-Forcing Equalizer (ZFE) to shape a stimulus pattern with the aim of reducing artifact length. The results find that using the ZFE stimulus has the potential to reduce artifact duration by more than 70%. Continuing work and current considerations for the hardware implementation of the equalizer are presented.
