(a) Entropy of the forward-directed SHG for the ${\mathrm{AP}}^{+/+}$ and ${\mathrm{AP}}^{-/-}$, where the higher value for the ${\mathrm{AP}}^{+/+}$ is consistent with larger structures ($p=0.036$). (b) The multifractal dimension for the ${\mathrm{AP}}^{+/+}$ and ${\mathrm{AP}}^{-/-}$ where the larger values for the ${\mathrm{AP}}^{+/+}$ are further consistent with larger, more organized structures.
