Figure 6.

Increase in mean number of spikes (MSC) with addition of the signal. The mean change in spike rate per stimulus presentation in three 25 msec windows centered at the center of the three signal pips is shown together with the SEs. The values are presented as a function of the signal-to-OFM ratio. Squares, circles, and triangles represent the CM, RF, and CD conditions, respectively. Top, MSC of the units shown in Figures 3, 4, 5. Left, Type II unit; middle, type III unit; right, type IV-t unit. For all units, the mean changes in spike rate are consistently higher in the CM condition than in the other conditions. Bottom, Population summary of the MSC for type II (left), type III (middle), and type IV-type IV-t units combined (right). The mean and the SE of 11 type II, 20 type III, and 14 type IV-IV-t units are shown. Data are included regardless of whether the responses showed an enhanced response to the signal in the CM condition according to the statistical analysis.
