When retinal ganglion cells are stimulated ex vivo by electrical current, short latency responses (within 30 ms) and long latency responses (over 30 ms) are evoked. The short-latency response is suspected to be originated from the direct electrical stimulation. For optimal stimulation protocol of retinal prosthesis, this short-latency response is getting important more and more. In this paper, we compared and evaluated performance of the three algorithms for the short-latency spike detection; suppression of artifacts by local polynomial approximation (SALPA), moving average filter (MAF), and forward-reverse filter (FR filter). The SALPA and the FR filter showed better detection performance comparing with the MAF algorithm.
