The average (bars) and peak (dots) energy deposition ($\mathrm{J}/{\mathrm{cm}}^3$) after positioning the intranasal light source in the: (a) nostril, (b) mid-nose, and (c) close to the nose ceiling (in proximity of the cribriform plate). The left inset shows the ROIs that receiving the highest (red) and second highest (orange) energy deposition; the right-inset shows the energy deposition ($\mathrm{J}/{\mathrm{cm}}^3$) map on the cortical surface. The locations of the numbered ROIs are shown in Fig. 1(c).
