FC and AC display frequency-dependent covariance

(A) Scatterplots between the 3 FC types (indicated to the left of the rows) and FLNe. For coherence and power correlation, each dot corresponds to a pair of areas, for which the combined FLNe in both directions was based on >10 labeled neurons (N = 60). For GC, each dot corresponds to an anatomical projection for which the FLNe in the same direction as the corresponding GC was based on >10 labeled neurons (100). FC values were averaged over monkeys before correlation analysis. Note logarithmic scaling on x and y axes.

(B) With both axes in log₁₀ units, subtraction of FC values between minimum and maximum AC values (left) can be interpreted as FLNe-related fold change of FC (right).

(C) FLNe-related FC change as a function of FC frequency. Log₁₀(FC) spectra (color coded, legend top right) have been aligned to individual peak frequencies before averaging over monkeys and then correlated with log₁₀(FLNe). Means over all trials ± 99.9% confidence intervals from bootstrap estimates over trials.
