Abstract :
An analog delay circuit which utilizes an inexpensive commercially available analog shift register is described. The delay circuit when used in conjunction with a window discriminator will display "on-line" visual confirmation of single neural events from extracellular recordings containing more than one spike class. The delay can be changed to include the entire spike waveform by adjusting a potentiometer in the delay circuit.
