Wide-dynamic coding of stimulus intensity. (A) An example of a WDR neuron that showed positive correlation between normalized firing rate (Z-score) and stimulus intensity. (B) The cumulative distribution of correlation coefficients (Z-score vs. laser intensity). The dotted lines indicate the upper and lower limits, respectively, of the normal range. Correlation coefficients that lie outside these limits were considered significant. Thus, the cumulative percentage outside the limits represents the proportion of WDR neurons for each region.
