Visualization of activity avalanche group means for all selected ICA components in DMN_(v)mpf and DMN_pcc by frame tiles in single planes with vertical time flow (from top to bottom) and 100 ms frame distances. The top frames are the analyzed ICA components cut and saturated at z-score thresholds 3 and 7, respectively. The vertically following frames are normalized BOLD data, cut and saturated at absolute threshold values, from left to right: 1 and 2; 0.8 and 1.5; 0.8 and 1.5; 0.4 and 0.8; 0.8 and 1.5, respectively. Values are color coded from low to high as red to yellow and blue to cyan, for positive and negative values, respectively. Activity data was smoothed with a Gaussian kernel (mean 0, standard deviation 1.2 pixels), and the voxel values outside the brain set to zero. The BOLD values are spatially registered and thus overlaid on a standard anatomy image.
