Peak ratio distributions for different stimulus frequencies. The histograms show the distributions of the primary to secondary autocorrelogram peak ratio for CS activity during MCtx stimulation. Each histogram shows the distribution for a different stimulus frequency, indicated above the histogram; n indicates the number of CS autocorrelograms from which the histogram was compiled. Note that for low-frequency (5 Hz) and high-frequency (20 Hz) stimulation, a large percentage of cells have a 0% ratio, whereas for the intermediate frequencies the distribution is centered on the ∼100% bin.
