Fig. 7: Spike counts over trials for different auditory paradigms.

Each panel represents the average response at every trial of the sequence, for all the units that presented significant SSA recorded with the multichannel probe (n = 20; 3 rats). A and B correspond to the random and periodic oddball paradigms, respectively, showing responses during a deviant tone (DEV; red) or a standard tone (STD; blue). C–E illustrate the responses to the control paradigms: Many-Standards (C; dark green), Cascade Ascending (D; medium green), and Cascade Descending (E; light green). Dots indicate the average spike count at each trial, while solid lines represent linear regression fits. F Comparison of the linear regression fits for all the paradigms. G Heatmaps showing the p-values of the comparison of linear regression model estimates (intercept, β₀, left; and slope, β₁, right) between paradigms. Darker colors mean smaller p-values, as indicated by the logarithmic color bar on the right. A Holm-Bonferroni correction for multiple comparisons was applied to the p-values in each table, with statistically significant values (*p < 0.05, **p < 0.01, ***p < 0.001) highlighted in bold. The underlying data for this Figure can be found in Supplementary Data 4.
