Reversibility and safety of TUS-mediated BBB opening. Representative T1-weighted MRI acquired 7 hours after TUS for (A) NHP skull and (B) human skull sonications depicting lack of contrast enhancement in regions of BBB opening (in Fig. 5A-B). Representative coronal H&E-stained brain slices of mouse brains sonicated bilaterally with an overlaid NHP skull fragment (C) or human skull fragment (D). No signs of damage were observed in any H&E-stained brain sections. Scale bars denote 1500 μm.
