Ultrasound Device Stimulates Multiple Brain Networks

Ultrasound Brain Stimulation:⁤ A Breakthrough in Neuromodulation

What: Researchers have developed a new ultrasound technique capable of simultaneously stimulating ⁣multiple, precisely ⁤defined points in the brain ‌- up to five at a time. this is achieved‍ through a device using hundreds of ultrasound transducers to create focused stimulation points via wave interference, similar to holography.

Where: Research conducted collaboratively by ETH Zurich, the University of Zurich, and New York University. Experiments were performed on mice in a laboratory setting.

When: The study was recently published (date not specified in the provided text). the technology builds on a decade of ‌research into⁣ low-intensity​ ultrasound neuromodulation.

Why it Matters: Current neuromodulation techniques have ​limited precision and can onyl target one brain region at a​ time. ‌The brain functions as a network; stimulating multiple points simultaneously is expected to be more effective at activating or‌ inhibiting these ⁤networks. This advancement⁤ holds potential for treating neurological and psychiatric disorders like Alzheimer’s, Parkinson’s, depression, and epilepsy. ⁣ It’s also non-invasive, avoiding the need for surgery.

What’s Next: initial clinical trials are underway⁣ to⁤ assess the efficacy of ultrasound neuromodulation for‍ conditions ​like Alzheimer’s, epilepsy, and tremors. Further research will likely focus on refining the technique and expanding its application to other brain‌ disorders. ​The lower ​intensity needed with multi-point stimulation‌ could also improve safety.
