Ramsey’s recent commentary in Nature Medicine highlights both the progress in this field and the challenges that remain. The study he discusses demonstrates how a person with tetraplegia was able to control a virtual drone using only their brain activity. While this showcases the expanding possibilities of BCIs, Ramsey emphasises that these systems must prove their clinical usefulness before they can become widely available.
Legal and ethical rules
One of the key hurdles is defining the standards for BCI safety and device function. In the United States, the Food and Drug Administration (FDA) and the implanted BCI collaborative community are working on regulatory frameworks. Europe, however, still lacks clear guidelines. "We need to establish legal and ethical rules to ensure that these technologies are developed responsibly and safely," Ramsey explains.
Master’s programme in neuroprosthetics
To accelerate the development of BCIs and ensure Europe remains competitive in this rapidly growing field, Ramsey is involved in setting up joint European degree master programme in neurotechnology across European academic partners of the NeurotechEU. This initiative aims to bridge the gap between neuroscience, neural engineering, and human applications. "There is currently no dedicated programme in Europe that trains students to work at the intersection of these disciplines," he says. "We want to equip the next generation of researchers and engineers with the skills to push this technology forward." The programme will prepare students to work in both academia and industry, helping to translate groundbreaking research into real-world applications.
The future of BCI
When asked about the future of BCIs, Ramsey offers an optimistic outlook. "In the next five years, we may see the first commercially available BCI devices approved for medical use. These will likely be simple systems that allow basic computer interaction for people with severe disabilities."
In ten years, improved decoding could enable precise robotic limb control or partial movement restoration. "The challenge will be ensuring these devices are safe, reliable, and can function over long periods without the need for frequent recalibration." In fifteen years, BCIs might allow speech via neural decoding or limb movement through spinal stimulators.
As the field advances, Ramsey stresses the importance of interdisciplinary collaboration and regulatory foresight." The possibilities are immense and the technology is moving fast, but there are still major technological and ethical questions to address. If we want to harness its full potential while protecting individuals' rights and safety, we need to act now."
