Rodney Gorham has reached an extraordinary milestone: five years with a brain-computer interface (BCI) implanted in his brain. This groundbreaking technology, developed by the startup Synchron, has allowed Gorham to control computers and smart devices using only his thoughts. At 65 years old, he battles amyotrophic lateral sclerosis (ALS), a condition that has stripped him of movement and speech. This device has become a vital lifeline, enabling him to interact with the world in ways he thought lost forever.
The Evolution of Synchron’s Technology
Synchron is one of several companies, including Elon Musk’s Neuralink, focused on commercializing BCIs to assist individuals with paralysis. Over the past five years, Synchron has refined its software and hardware, with Gorham playing a crucial role in this evolution. As the longest participant in the BCI trial that began in December 2020 in Australia, Gorham’s experiences have been instrumental in shaping the future of this technology. Tom Oxley, the founding CEO of Synchron, acknowledges Gorham’s contributions to the development of new interaction methods and application integrations.
The Stentrode: A Revolutionary Device
At the heart of Synchron’s innovation is the Stentrode, a small mesh tube designed to collect neural signals from the brain. Inserted via the jugular vein, the Stentrode navigates to the motor cortex, the brain region responsible for voluntary movement. A device implanted in Gorham’s chest captures these signals and transmits them to an external receiver, allowing him to control devices with his thoughts.
The company is preparing for a pivotal trial necessary for regulatory approval, collaborating with the U.S. Food and Drug Administration to determine the trial’s clinical endpoints. Assessing the effectiveness of a BCI poses unique challenges compared to traditional medical devices, a situation that the industry is still navigating.
Decoding Brain Activity
BCIs rely on sophisticated algorithms to translate brain activity into actions. For instance, Gorham can think about making a fist to execute a mouse click, even though he cannot physically perform the action. The technology must accurately recognize these neural patterns, which is critical for the device’s functionality.
Initially, Gorham used the BCI for single clicks. Over time, he progressed to multi-clicks and sliding controls, akin to adjusting a volume knob. Now, he can move a computer cursor, demonstrating two-dimensional control within a digital interface.
Expanding Possibilities
Gorham has explored various applications for his implant, contributing to the development of features like Switch Control, which allows BCI users to manage Apple devices with their thoughts. In a recent demonstration, he showcased his ability to manage multiple smart devices, including playing music, adjusting lighting, and operating a robotic vacuum.
Zafar Faraz, a field clinical engineer for Synchron, visits Gorham bi-weekly to monitor the device and troubleshoot any issues. These sessions foster experimentation, pushing the boundaries of what Gorham can achieve with the technology. Together, they have tested various scenarios, including using two iPads simultaneously and even controlling a robotic arm at a remote lab.
A Personal Connection to Technology
Gorham’s background as an IBM software salesman has made him uniquely suited to contribute to BCI development. His wife, Caroline, highlights how Gorham’s experience in IT has allowed him to communicate effectively with technology developers. After sessions with Faraz, Gorham often expresses joy at being part of such innovative work.
Learning from Experience
Through ongoing field visits, Synchron has identified areas for improvement in its system. Currently, the device relies on a wire cable that transmits brain signals to an external unit. However, the company has learned that this setup can complicate usage, especially for individuals with paralysis. Future iterations aim to eliminate the wire, enhancing ease of use for caregivers and patients alike.
The Personal Impact of ALS
Despite the advancements in BCI technology, Gorham’s condition has gradually deteriorated over the years. Operating the device demands significant concentration, and he tires more easily now. Previously capable of long interviews, Gorham now struggles with extended text conversations. This reality raises crucial questions about the long-term viability and utility of BCIs for patients with progressive neurodegenerative diseases.
Insurance coverage for such devices remains uncertain, particularly for patients whose life expectancy may be limited. While individuals with stable forms of paralysis could potentially use BCIs throughout their lives, they too may experience mental fatigue from prolonged use.
The Human Element in Technology
Caroline emphasizes the importance of considering the human aspect in BCI development. Each patient’s experience is unique, and companies must prioritize this individuality in their designs. Understanding the diverse needs of users will be essential for BCI technology to thrive and become truly beneficial for those who need it the most.
Conclusion
Rodney Gorham’s journey with a brain-computer interface reflects both the promise and challenges of this cutting-edge technology. As advancements continue, the interplay between innovation and the human experience will shape the future of BCIs. The path forward will require not only technical improvements but also a deep understanding of the diverse needs of individuals with varying conditions.
