Figure 4From: Non-identical smoothing operators for estimating time-frequency interdependence in electrophysiological recordings The linear regression analysis between analytic coherence (X) and the magnitude of the estimate (Y) for the first simulated dataset. Top row shows the regression line for a = 0.5 and f = 0.6 Hz for methods 1 to 3 (panels A to C, respectively). Bottom row show the correlation coefficient r for different amplitudes (a ∈ [0.01,0.5]) when coherence is modulated at 0.6 Hz (D) 0.9 Hz or 1.2 Hz (E).Back to article page
