Figure 14.

Mean response strength of AAF neurons to specific tonal stimuli before (A) and during (B) A1 deactivation. The color of each square in the table represents the average number of spikes evoked at the corresponding frequency–intensity combination. C, Subtraction of the response strength of AAF before A1 deactivation (A) from the response strength of AAF during A1 deactivation (B). Note that the decrease in driven activity of AAF cells during A1 deactivation is not uniform throughout the frequency–intensity domain. Large regions of responsive areas resulted in a net effect of no change indicated by a white box. In C, regions circumscribed by the thick black line indicate statistically significant changes at p < 0.05; n = 116.
