[A method for real time separation of multiple unit action potentials from intact nerves (author's transl)]

1 A method is described for on line separation and classification of individual action potentials from multi unit extracellular recordings from intact nerves. 2 this method is based on the simultaneous determination of several of the features of each action potential, especially their form and velocity. 3 provided that only a few conditions are fulfilled, each of the action potentials can be recognized, and the recognition work is achieved at the time of the generation of the action potentials. 4 The prerequisite conditions are the following: the nerve diameter should not exceed a few tenths of a millimeter. The nervous filament must be carefully dissected from the surrounding tissue. The overall frequency of the action potentials should not exceed 1000 spikes/sec.
