Bar plots display the average fraction of C0/I objects in each region, with dotted black lines indicating the limits for categorizing NESTs as high-activity or low activity, that is ${\overline{f}}_{C0/I}\pm {\sigma }_{f_{C0/I}}$. The colour of the bars represents the regime of each region, and black dots represent the values of f_C0/I in each NEST, along with its corresponding standard deviation, in decreasing order. Regions within each regime are ordered by f_NEST,max, the maximum value of f_C0/I in NESTs. The value f_C0/I = 0.1 is marked in all panels for comparison.
