Figure 4. Geometrical core-periphery organization in brain networks.
(A) Core quality 
(5) in the 
parameter plane for a typical participant (3), scanning session (1), sequence type (EXT), and experimental block (1). (B) Distribution of the 
and 
values that maximize the 
-score. We compute this distribution over all network layers, participants, scanning sessions, and sequence types. The 
parameter is much more localized (its standard deviation is 0.05) than the 
parameter (its standard deviation is 0.26). (C) Mean core shape. We plot the ordered vector of 
values. We have set the values of 
and 
to the mean values of those that maximize the 
-score for all network layers, participants, scanning sessions, and sequence types.
