Excitability changes induced in the motor cortex by transcranial ultrasound stimulation

Transcranial Ultrasound Stimulation (TUS) is an emerging neuromodulatory technique that uses ultrasonic waves to noninvasively stimulate the brain. Most experiments utilize transcranial focused ultrasound (TFUS) due to high spatial resolution and deep focal penetration. Diagnostic ultrasound (dUS), typically used in medical imaging, holds important advantages over TFUS for the purpose of neuromodulation, including well-established parameters for safety, widespread availability, and ease of use. With these features in mind, we investigated the possibility of altering cortical excitability with TUS using a diagnostic system.
