How does ultrasound excite neurons?

Focused ultrasound excites cortical neurons by opening specific mechanosensitive ion channels, leading to gradual calcium accumulation, activation of calcium-gated channels, depolarization and spiking. Congratulations to Sangjin and collaborators on this detailed biophysical study.
