Figure 4From: Power-law for axon diameters at branch pointExperimentally observed spread in the branching exponent may arise from the measurement errors. The histogram shows the distribution of the exponent η, Eq. (9), calculated for each axon bifurcation [20]. The average exponent is η = 2.67. The line shows the simulated distribution of the exponent obtained in the presence of measurement errors.Back to article page
