Analysis: Raw firing level vs step cycle


The firing levels at each action potential are displayed with respect to cycles on the waveform selected by the "Cycle W.F. #". That is, for each spike on the waveform selected by the "Spike W.F. #", the level is measured at that same location on the waveform selected by the "Amplitude W.F. #", and displayed on the graph at the position in the current cycle where this spike occurred. The parameters "W.F. amplitude delay" and "W.F. amplitude window" indicate a range of points, relative to the point where the action potential occurred, used to obtain a level reading on this waveform. The range of voltage levels can be restricted to a smaller range, by setting the parameters "Min W.F. amplitude" and "Max W.F. amplitude". Only action potentials whose associated waveform level readings stay within these bounds will be included in the graph.

This graph is most useful when dealing with a differentiated waveform. Spikes on the differentiated waveform, indicating high rates of change in level on the original waveform, can be used to trigger firing level measurements on the original waveform.

If the spike trains for the waveform selected by the "Spike W.F. #" have been properly set, statistics will be given for activity on this waveform, relative to the above cycles.
