Representation of FUS procedure, system, and software. (a) The RK50 stereotactic system from FUS Instruments used during our experiments. (b) A schematic of the experimental set-up used in this study. Of note, a 27-gauge tail vein catheter was used during our procedure for delivery of the bubble infusion. (c) Skull landmarks lambda and bregma are identified with the stereotactic system after an incision has been made in the mouse’s shaved scalp. (d) A Python-based software uses a mouse brain atlas registered to the identified skull landmarks to carry out a sonication treatment plan of multiple sequential points. (e) A hydrophone returns an acoustic signal that is transformed by the software into a visual representation of the acoustic spectra from which the area under the curve (AUC) is calculated. The authors thank April Gill for creating the drawing in (b) and kindly providing it to us for publication.
