Classification of Action Potentials Recorded from Peripheral Nerves with Cuff Electrodes

In order to extract neural information, action potentials recorded with cuff electrodes from peripheral nerves were classified into unit activities. The classification was performed based on their waveforms, as it was considered that they were affected by the radius of nerve fiber and the distance between fiber and recording electrode. This study focused on automatic classification method. Action potentials were grouped into each unit by hierarchical cluster analysis and a new eriterion. The method proposed in this study might be applicable to automatic classification of nerve action potentials, because it provided the reliable estimation of unit activities.
