This Chinese Startup Wants to Build a New Brain-Computer Interface—No Implant Required
The Rise of Non-Invasive Brain-Computer Interfaces: A New Era in Neurotechnology
China's brain-computer interface (BCI) industry is rapidly growing, with a new company, Gestala, emerging as a leader in the field. Founded in Chengdu with offices in Shanghai and Hong Kong, Gestala aims to revolutionize the way we interact with our brains without the need for invasive implants. The company's approach uses ultrasound technology to stimulate and eventually read from the brain, a method that could potentially treat a wide range of neurological disorders.
Ultrasound Technology: A Novel Approach to BCI
Ultrasound technology is best known for its use in medical imaging and diagnostics, such as monitoring fetal development during pregnancy. However, researchers have also explored its potential to treat diseases, not just diagnose them. Depending on the intensity of the ultrasound, it can be used to destroy abnormal tissue, such as blood clots or cancer, or modulate neural activity without the need for surgery. Focused ultrasound treatments are already approved for Parkinson's disease, uterine fibroids, and certain tumors.
Gestala's first-generation device will be a stationary benchtop machine that delivers focused ultrasound to the brain to treat chronic pain. Pilot studies have shown that stimulating the anterior cingulate cortex, a brain region involved in the emotional component of pain, can reduce pain intensity in people for up to a week. The company is in discussion with some hospitals in China that are interested in testing the technology.
The Potential of Ultrasound-Based BCI
Gestala's second-generation device will be a wearable helmet that will allow patients to use it at home under the guidance of a physician. Beyond chronic pain, the company wants to gradually expand to other indications, including depression and other mental illnesses, as well as stroke rehabilitation, Alzheimer's disease, and sleep disorders. The ultimate goal is to use ultrasound to read the brain as well, detecting brain states associated with chronic pain or depression, for instance, and delivering therapeutic stimulation to the precise area of the brain with abnormal activity.
A New Era in Neurotechnology
Gestala's approach is not limited to treating neurological disorders. The company's technology could potentially be used to enhance human cognition, allowing people to learn and remember information more efficiently. However, the company's CEO, Phoenix Peng, emphasizes that the goal is not "enhancement" of humans but healthier neural functions.
The Challenges Ahead
While Gestala's technology holds great promise, there are still significant challenges to overcome. One of the main issues is that changes in blood flow are more sluggish than neural activity, which may not make it ideal for certain applications, such as translating speech. Additionally, the skull weakens and distorts ultrasound signals, making it difficult to interpret neural activity. Researchers have been able to interpret neural activity with ultrasound only by removing a portion of the skull to create a "window" into the brain.
Forward-Looking Thoughts
The development of non-invasive BCI technology has the potential to revolutionize the way we interact with our brains. Gestala's approach using ultrasound technology is a significant step forward in this field. While there are still challenges to overcome, the potential benefits of this technology are vast. As researchers continue to push the boundaries of what is possible, we may see a future where people can control devices with their minds, communicate with each other more effectively, and even enhance their cognitive abilities.
The Future of BCI
The future of BCI technology is exciting and rapidly evolving. As researchers continue to explore new approaches and applications, we may see a future where BCI technology is integrated into our daily lives. From treating neurological disorders to enhancing human cognition, the potential of BCI technology is vast. As we move forward, it will be essential to address the challenges and limitations of this technology193 words,
