$\mathrm{A}\beta$ peptide induces VPD reduction in mouse brain. VPD maps derived from OCT data before and 1, 7, and 14 days after amyloid infusion in CFS (a). Data were expressed as percentage values relative to before treatment. The percentage of (b) total VPD and (d) local VPD selected in the anterior (red squares in c) and posterior (blue squares in c) parts of the brain, were also plotted over monitoring time, respectively.
