Reading Minds with Ultrasound: Less-Invasive Technique for Brain's Intentions (2021)

Researchers reported a technique using ultrasound to read brain activity. The method aims to decode a person’s intentions. It is described as less invasive than traditional approaches. Ultrasound waves are directed toward targeted brain regions. The signals are interpreted to infer intended actions. The study was published in 2021. The approach could broaden non‑invasive neural monitoring. Further work will assess accuracy and practical applications.
