A new ultrasound “helmet” could transform the treatment of neurological conditions by offering a non-invasive alternative to deep brain stimulation (DBS), researchers have found.
Developed by teams at Oxford University and University College London, the device uses 256 ultrasound sources inside an MRI scanner to precisely target brain regions as small as a grain of rice. Unlike DBS, which requires implanting electrodes deep in the brain, the helmet delivers mechanical pulses without surgery.
In early trials, seven volunteers underwent ultrasound targeting of the lateral geniculate nucleus, a key visual pathway. The system achieved remarkable accuracy, producing measurable and lasting effects in the visual cortex. Researchers believe the same approach could one day ease Parkinson’s tremors by modulating motor control regions.
The project, which has taken more than a decade, could also open new possibilities for treating Alzheimer’s, Tourette syndrome, depression, chronic pain, and addiction. Experts have hailed the breakthrough as a milestone in neuroscience, with further clinical testing already under way.
