Additionally, we discuss advancements in FUS neuromodulation, which could complement lesioning by providing temporary or reversible symptom relief.
Ultrasonic neuromodulation has the unique potential to provide non-invasive control of neural activity in deep brain regions with high spatial precision and without chemical or genetic modification.
These efforts have resulted in already-useful neuroscience tools, including high-resolution hemodynamic functional imaging, focused ultrasound neuromodulation, and local drug delivery.

Activation of the implicated mechanosensitive channels causes gradual calcium accumulation that is amplified by calcium-gated and voltage-gated channels to generate burst firing.
The activation of these channels results in a gradual build-up of calcium, which is amplified by calcium- and voltage-gated channels, generating a burst firing response.
Focused ultrasound excites primary murine cortical neurons in culture through a primarily mechanical mechanism mediated by specific calcium-selective mechanosensitive ion channels.
Here, we show that focused ultrasound excites primary murine cortical neurons in culture through a primarily mechanical mechanism mediated by specific calcium-selective mechanosensitive ion channels.

Pharmacological and genetic inhibition of specific ion channels reduces neuronal responses to ultrasound, whereas overexpression of these channels strengthens ultrasonic stimulation.
Pharmacological and genetic inhibition of specific ion channels leads to reduced responses to ultrasound, while over-expressing these channels results in stronger ultrasonic stimulation.
Ultrasound readily permeates the brain and in some cases the skull, with a fundamental resolution on the order of 100 μm and 1 ms.
