Sound waves, particularly ultrasound, show promise in modulating brain activity through techniques like sonogenetics, where genetically modified cells respond to ultrasonic pulses, allowing non-invasive control of neurons in animals like worms and mice. Developed by researchers at the Salk Institute, this method activates specific brain regions without surgery, potentially treating disorders such as Parkinson’s by stimulating neural circuits. Unlike optogenetics, which uses light and requires invasive fibers, ultrasound penetrates tissue easily, offering advantages for human applications. Rhythmic sounds can also synchronize brain waves, influencing emotions and perceptions, as seen in music’s effects on group behavior. However, true “mind control” remains science fiction; current tech is limited to lab settings, ethical concerns abound, and human trials are nascent. Pseudoscientific claims of weaponized sound for coercion lack evidence, often tied to conspiracy theories. Future developments could enhance neuromodulation therapies, but safety and precision are key challenges.
