ROC analysis quantifying A1 habituation. ROC values relative to average firing rate elicited by tone A1 as a function of time. Data are combined from reports of “small” frequency difference and “large” frequency difference and are aligned relative to tone A1 (sliding window of 20 ms that moved in 2 ms increments). Color corresponds to the frequency difference between the tone-A and tone-B sequences; see legend. Thick lines indicate mean values; shading indicates s.e.m. Colored lines at the top of the graph indicate the time when mean ROC values were significantly different than chance (t-test, H0: ROC value = 0.5, p < 0.05; see legend). The black and gray rectangles above the x-axis show the time course of each tone burst (tone-As and tone-Bs, respectively) in the auditory sequence.
