Spike Tab

Spike analysis software for computing raster plots, peristimulus time (PST) histograms and interspike-interval histograms. Spike occurrences are determined by a y-threshold level detector on positive slope deflections.

Set the y-threshold crossing level that best suits your data.

Use the wave increment controls on NeuroMatic’s control panel to step through your data. The number of spikes detected is displayed next to Spikes.

Use the channel and wave select controls to select the channel and set of waves you wish to analyze. Select All Waves button. Results are displayed in a spike raster plot and table.

Use the Spike Analysis controls to compute averages and histograms.

Spike Detection

F(t): if you wish to compute spike-threshold crossings on differentiated or double-differentiated data waves, click the F(t) checkbox on the currently selected channel graph and choose the desired function.

Threshold: set the absolute y-threshold crossing level. Spike occurrences are determined by a y-threshold level detector (see Igor Pro’s FindLevels function) for only those values on a positive slope deflection.

t_bgn, t_end: use these parameters to set the analysis time window. Enter -inf, inf to search the entire wave.

All Waves: click this button to compute spike-threshold crossings on all currently selected waves (Chan / Wave Select). Results are displayed in a Raster Plot.

Table: select this button to view / edit spike raster waves in a table.

Raster Waves are created in the current data folder with the following Name Convention: “SP_R” + X/Y + Wave Select String + Channel + Overwrite Sequence Number (i.e. “SP_RX_RAll_A0”).

X Waves (“SP_RX”) hold the raster spike times (msec).

Y Waves (“SP_RY”) hold the data wave number from which spike times were derived.



Spike Raster Analysis

Raster Wave Select: select the raster x-wave you wish to analyze with this drop-down menu. The y-wave will automatically be selected.

Raster Plots: create a raster plot of the currently selected raster x-y waves.

Avg Rate: compute the average rate of the currently selected raster x-y waves.

PST Histo: compute a peristimulus time histogram of the currently selected raster x-y waves.

ISI Histo: compute an interspike-interval histogram of the currently selected raster x-y waves.

Spikes 2 Waves: copy spikes to individual waves, beginning with the prefix “SP_Rstr”. The prefix name will automatically be added to NeuroMatic’s wave prefix list. Select the appropriate spike prefix to analyze the individual spikes.
