ALS Patient Pioneers Brain-Computer Interface, Enabling Communication and Control

As a rare form of Lou Gehrig’s disease progressively paralyzes his body, Australian resident Rodney Gorham is at the forefront of brain-computer interface (BCI) technology, utilizing a groundbreaking link between his brain and a computer to maintain connection with the world. Gorham, 63, communicates by using his eyes to select letters on a screen and “clicking” on words with his mind.

The Synchron Stentrode Implant

The technology enabling Gorham’s communication is the “stentrode,” an 8mm stent implanted in his brain to detect neural activity. Developed by US-based company Synchron, the stentrode allows Gorham to continue accessing the internet, sending messages, and playing video games. Synchron has been testing the stentrode for the past two years, receiving regulatory clearance for human trials before Elon Musk’s Neuralink gained significant attention Medical Xpress.

How the System Works

Gorham’s implant connects to a receiver and transmitter unit located under the skin in his chest. This system has dramatically changed his life, allowing him to maintain a degree of independence and connection despite the debilitating effects of Amyotrophic Lateral Sclerosis (ALS). ALS causes progressive paralysis of the respiratory muscles, trunk, arms, and legs. While the disorder is expected to gradually disable his movement, it is not predicted to be fatal, potentially allowing Gorham to live for another 20 years The Straits Times.

A “Slice of Life” Despite Paralysis

According to his wife, Carolyn, the brain implant provides her husband with a “slice of life,” enabling him to communicate and engage in activities like playing games. While Gorham has adapted his gaming preferences to turn-based strategy games like city-building simulations due to the limitations of his physical movement, the BCI allows him to continue enjoying these activities.

Contributing to Technological Advancement

Rodney Gorham’s involvement extends beyond being a recipient of the technology; he has actively contributed to its development. Zafar Faraz, a field clinical engineer for Synchron, notes that Gorham directly contributed to the development of Switch Control, a modern accessibility feature Apple announced last year that allows BCI users to control iPhones, iPads, and the Vision Pro with their thoughts.

Demonstrated Capabilities

In a demonstration at an Nvidia conference, Gorham showcased the capabilities of the implant, using it to play music, control lights and fans, activate a pet feeder, and operate a robotic vacuum cleaner in his Melbourne home Medical Xpress.

Ongoing Refinement of the Technology

Zafar Faraz visits Gorham twice weekly to monitor the device’s performance, troubleshoot issues, and gather data to improve the system’s reliability and user-friendliness. Synchron is currently working on a second-generation system that will eliminate the demand for a wire connecting the implant to an external unit, addressing a challenge identified through user feedback – the reliance on assistance to maintain the connection Medical Xpress.

From IT Professional to Tech Contributor

Prior to his diagnosis with ALS in 2016, Gorham worked as an IBM software salesman. His wife, Caroline, notes that his current role in developing the BCI technology aligns with his professional background, mirroring his previous work of gathering customer needs and collaborating with developers to create solutions.
