Using your graph and R=>P as the path, the short circuit is the best:
           Rate   breadth    limbic     depth limbic_sc
breadth   158/s        --      -34%      -42%      -60%
limbic    238/s       51%        --      -13%      -39%
depth     274/s       73%       15%        --      -30%
limbic_sc 392/s      148%       65%       43%        --
