Transcranial focused ultrasound

Transcranial focused ultrasound (tFUS) is a form of focused ultrasound (FUS) which is being investigated for the potential non-invasive treatment of psychiatric and neurological disorders.^[1][2][3] It differs from other non-invasive brain stimulation methods such as magnetic (transcranial magnetic stimulation or TMS) and electrical (transcranial direct-current stimulation or tDCS) in that it has higher spatial resolution and precision (millimetric) and is able to reach deep brain structures.^[1][3] Depending on the parameters, tFUS can inhibit, stimulate, and even ablate brain tissue.^[1] Only a handful of clinical studies of tFUS for psychiatric conditions have been conducted as of 2024.^[3]
