Figure 3.

FUSIN delivery of 800CW-BSA to the brainstem at different FUS pressure levels (groups 1, 2, 7, and 8 in Table 1). (A) Fluorescence images, bright field images, and their overlays of representative ex vivo mouse brain slices of the brainstem at different pressure levels. (B) Quantification of the 800CW-BSA fluorescence intensity for different pressure groups and the control (IN only) group without FUS (Mann–Whitney U test; *: P < 0.05; **: P < 0.01; ns: not significant). The scale bar is 5 mm.
