Abstract

A method for classifying action potentials to estimate a sensory unit activity was developed. The classification of action potentials based on their waveforms involves a pattern classification problem without supervised signal. Some methods depended on an operator for specifying parameters due to the lack of a standard criterion for classification. Therefore, we have proposed an objective classification method in this paper. The performance of our method was evaluated with a simulated signal generated by a peripheral nerve model. Our method provided more appropriate classification results against the influence of the noise process than the conventional method whose reliability was reported to be high in previous studies. The classification results of our method applied to the cuff recordings suggested that there were several different stretch receptors of different characteristics, which agrees with previous reports. © 2002 Wiley Periodicals, Inc.
