Analysis: Firing level vs firing frequency

Home › Software › Analysis Help › Methods › Firing level vs firing frequency


The firing levels at each action potential, calculated as for the "Raw firing level vs step cycle" graph, are displayed with respect to the instantaneous frequency of each action potential. No point is displayed for the first spike in the range to be analysed, since no previous spike exists to permit a frequency calculation. If the spike trains for the waveform selected by the "Spike W.F. #" have been properly set, frequencies are calculated and points are displayed only for spikes in the same spike train, and no point is displayed for the first spike in each train.
