Noise-Assisted Instantaneous Coherence Analysis of Brain Connectivity
Figure 9
Grand average of Fourier-transform-based coherence in Visible (a) and Invisible (b) conditions. Note that the time-evolving coherence was obtained using a moving window approach, in which the window size used was 500 msec long, with a step size of 10 msec. As a result, coherence was only displayed between 250–750 msec.
