Real-time waveform analysis of multichannel nerve impulses with a multimicroprocessor system

  • M. Ikeda
  • N. Hoshimiya


A new system for the online real-time waveform separation of the nerve impulses recorded from multichannel extracellular electrodes placed to the peripheral nerve trunk has been developed using two microprocessors and a graphics computer. One microprocessor (Intel 8085) performs nerve impulse detection and the other (Intel 8086) separates nerve impulses by clustering in the two-dimensional histograms representing the distribution of the parameters extracted from their waveforms. System performance was examined with two channel impulses recorded from the nerve trunk innervating the Sartorius muscle of a frog. These data could be classified into 6–8 different groups in real time.
