The ultrasound waves are targeted at specific brain regions without any incisions. Magnetic Resonance-Guided (MRg): MRI is used to visualize and guide the procedure in real-time. This provides accurate imaging of the brain and allows for precise targeting of the ultrasound. [[Focused Ultrasound]] (FUS): This involves the use of high-intensity sound waves that are focused on a specific target within the brain. The focused ultrasound can create thermal or mechanical effects, depending on the application. ---- [[Transcranial]] [[magnetic resonance-guided focused ultrasound]] at low intensities has been reported to directly evoke responses and reversibly inhibit function in the central nervous system. While some doubt has been cast on the ability of [[ultrasound]] to directly evoke neuronal responses, spatially-restricted [[transcranial ultrasound]] has demonstrated consistent, inhibitory effects tFUS predominantly causes neuroinhibition and the primary biophysical mechanism is the thermal effect of [[focused ultrasound]] ((Darrow DP, O'Brien P, Richner TJ, Netoff TI, Ebbini ES. Reversible neuroinhibition by focused ultrasound is mediated by a thermal mechanism. Brain Stimul. 2019 Jul 23. pii: S1935-861X(19)30299-2. doi: 10.1016/j.brs.2019.07.015.
