The evolution of cost-efficiency in neural networks during recovery from traumatic brain injury
Fig 5
2-D histograms represent the distribution of connections that are incident upon ROIs within left frontal DMN (top) and Right Ventral Temporal/Parietal Attention (bottom) as a function of connection length and connection strength.
A contour line (e.g. contour line of cost = 80) represents all possible values of connection distance and connection strength that can produce the same cost value (distance*strength).
