Fundamental Activity Constraints Lead to Specific Interpretations of the Connectome
Fig 8
Analysis of changes in connectivity.
A Top panel: relative changes in population-specific intrinsic indegrees summed over target populations and averaged across areas, . Bottom panel: changes in the indegrees within and between exemplary areas V4 and CITv relative to the total indegrees of the target populations, i.e.,
. Populations ordered as in Fig 7C. B Pearson correlation coefficient of the changes of the internal indegrees
between all pairs of the 32 areas. Areas ordered according to hierarchical clustering using a farthest point algorithm [31]. The heights of the bars on top of the matrix indicate the architectural types of the areas (types 1 and 3 do not appear in the model) with color representing the respective clusters. C
