H&E-stained sections for acute (A, C) and 72‒h recovery (B, D)rats. Both rats received the same ultrasound exposures in the samelocation in the brain, indicated by an asterisk. Low-magnificationimages of the entire brain section (A, B) depict the exposed and controlhemispheres. A cutting artifact is observed in (A) on the right corticalregion and is unrelated to the ultrasound exposure. A × 10magnified region (inset in A and B) depicts the cellular architecture in theexposed regions of the brain. Evidence of perivascular hemorrhage in thetarget region can be observed in the acute exposure.
