FUN26, the Focused Ultrasound Neuromodulation Conference, is an international forum dedicated to advancing research and applications in transcranial ultrasound stimulation (TUS). Held from July 22–24, 2026, at PariSanté Campus (Paris, France), FUN26 brings together researchers, clinicians, and industry professionals to explore cutting-edge developments in non-invasive ultrasound neuromodulation. The conference highlights innovative techniques and technologies for targeting deep brain structures, with particular emphasis on advancing measurement, stimulation, pathology, and translation from bench to clinic. Through keynote lectures, research presentations, and interactive discussions, FUN26 fosters critical dialogue and collaboration across the global TUS community.
