To quantify the overall relationship between FSI firing rate dependence on gamma-50 power and gamma-80 power, we plotted the slopes of the linear regression fits or firing rate relative to gamma-50 and gamma-80 power in a scatter diagram (Figure 13B). Only neurons with significant firing rate dependence (corrected for multiple comparisons) on either gamma-50 power, gamma-80 power, or both were plotted. While overall there was a significant negative correlation between gamma-50 and gamma-80 power tuning (Figure 13C), this relationship depended on the strongly tuned neuron in the top left corner. Removing this neuron from analysis resulted in a non-significant correlation of 0.0023 (p = 0.99) suggesting that FSI firing rates are tuned to gamma-50 and gamma-80 power independently. While the coherence of the example neurons in Figures 13A,B did not show a significant dependence on gamma-50 or gamma-80 power, about half of FSIs did show such a relationship for at least one of the power bands (Figure 13D). However, we did not find significant relationships between coherence tuning to gamma-50 and gamma-80, coherence at gamma-50 and firing rate tuning to
