Analogic delay lines for electrophysiological signals: practical approaches in CNS spike-activity analysis.
In extracellular microelectrode recordings of single PT-neurons, the time-shift of the signals by means of two different analogic delay lines allowed both the morphology of the spontaneous spikes and the related periods of antidromic unresponsiveness to be carefully evaluated. It has been shown that the limitations of the FM-type recorder delay technique can be avoided employing an integrated shift-register delay line for analogic signal processing.
