Low Intensity Focused Ultrasound for Tobacco Use Disorder: High Resolution Targeting of the Human Insula

"Low-intensity focused ultrasound (LIFU) provides an energy source with millimeter resolution that can be focused anywhere in the brain safely and effectively for non-invasive and transient neuromodulation. LIFU is an important advance and of great significance for brain-mapping efforts, diagnostics, and therapies in neuroscience and particularly promising for addiction therapy as it provides unprecedented non-surgical access to the brain regardless of depth.~Much lower intensities of focused ultrasound (LIFU) are used so that tissue damage does not occur, but neural activity can be modulated. LIFU utilizes acoustic energy at much lower levels to affect tissue by mechanical effects."
