Summary of Numerical Results
The following information is available in the Summary of Numerical Results
Column Description
Variable Variable name.
Reference Reference variable name.
NumRefEvents The number of reference events used in calculation.
YMin Histogram minimum.
YMax Histogram maximum.
Spikes The number of spikes used in calculation.
Filter Length The length of all the intervals of the interval filter (if a filter was used) or the
length or the recording session (in seconds).
Mean Freq. Mean firing rate (Spikes/Filter_Length).
Mean Hist. The mean of the histogram bin values.
St. Dev. Hist. The standard deviation of the histogram bin values.
St. Err. Mean. Hist. The standard error of mean of the histogram bin values.
Conf. Low Lower confidence level.
Conf. High Upper confidence level.
Mean Expected mean value of the histogram. If Z-score normalization is
specified, this value is zero and the expected mean value of the histogram
with Counts/Bin normalization is shown in Z-score Mean.
Norm. Factor Normalization factor. Bin counts are divided by this value. See
Normalization in Algorithm below.
Z-score mean Expected mean value of the histogram before Z-score normalization (in
other words, confidence mean). See
Confidence Limits for details .
Mean Before Ref. Mean of the histogram before the reference event (i.e. for all the bins
before zero on time axis).
Bins Before Ref. The number of bins before the bin that contains zero on time axis.
Zero Bin The index of the bin that contains zero on time axis.
Background Mean The mean of the histogram background for the peak and trough analysis.
See Peak and Through Statistics below.
Background Stdev The standard deviation of the histogram background for the peak and
trough analysis. See Peak and Trough Statistics below.
Peak Z-score Peak Z-score. See Peak and Trough Statistics below.
Peak/Mean Histogram peak value divided by the background mean value.
Peak Position Peak position (in seconds).
Peak Half Height The Y value of the half height of the peak, i.e.
histogram_background_mean + (peak-mean)/2.
Peak Width at Half
Height Peak width at the peak half height level (in seconds).
