Key Moments
Ultrasound-based vagus nerve stimulation for anxiety
John Hacker explains how focused ultrasound can precisely stimulate the auricular branch of the vagus nerve in the ear, unlike electrical stimulators that lack precision. He describes how Hebbian learning allows the vagus nerve to strengthen over time with consistent stimulation, eventually enabling self-regulation without the device.
"So you're literally working out your vagus nerve with ultrasound so that it gets stronger so that you can self-regulate without using the tech."
