Coherence within and across regions of interest.

<p>A. Interquartile range of coherence within and between regions of interest. Coherence was greatest among channels that shared the same region. This effect was greatest among channels within the parietal cortex. B. Heatmap visualization of channel-wise coherence across all regions of interest. The opacity (i.e., whiteness) of each cell indicates the degree of coherence between all (N_channels = 12) channels.
