Researchers from UCL and the University of Oxford have unveiled a groundbreaking ultrasound device capable of precisely stimulating deep brain regions non-invasively. This innovation bypasses the need for surgery, a significant leap forward for neurological research and the treatment of conditions such as Parkinson's disease, depression, and essential tremor.

The new technology significantly improves upon existing transcranial ultrasound stimulation (TUS) methods, which have struggled to target deeper brain structures with adequate precision. The developed system, detailed in Nature Communications, can target areas approximately 1,000 times smaller than conventional ultrasound devices and 30 times smaller than previous deep brain ultrasound systems. This precision is achieved through a helmet-like device with 256 elements that emit focused ultrasound beams, coupled with a soft face mask to stabilize the head, allowing for targeted modulation of neuronal activity.

Experiments on human volunteers successfully demonstrated the device's ability to modulate activity in the lateral geniculate nucleus (LGN) within the thalamus, a key structure for processing visual information. Functional MRI scans confirmed increased activity in the visual cortex during stimulation and showed sustained decreases in activity for at least 40 minutes afterward, indicating the potential for lasting functional changes in the brain without conscious perception of alteration by the participants.

Market Signals

The neurotechnology and therapeutic ultrasound sectors are poised for disruption, with a shift towards non-invasive solutions challenging established invasive treatment providers.
Companies in advanced ultrasound components, MRI integration, and neurological device manufacturing may experience positive market sentiment and increased demand.
The emergence of spinout companies like NeuroHarmonics signals a strong commercialization pathway for this technology, potentially attracting significant investment.

Winners & Losers

Potential winners include developers of advanced ultrasound technology, non-invasive therapy specialists, and diagnostic imaging providers with MRI capabilities. Companies heavily invested in traditional invasive Deep Brain Stimulation (DBS) may face declining market share if this technology proves superior and widely adopted. The supply chain for high-precision ultrasound transducers and specialized electronics will see increased demand.
