A digital rendering of a hand flickers against the stark contrast of a black interface. It is the focal point of J. Galen Buckwalter’s gaze, as he endeavors to prompt one of the digital fingertips to twitch – powered solely by the force of his thoughts. Following an accident in his teenage years that resulted in a broken neck, Buckwalter has spent over half a century unable to feel his fingers. However, a brain computer interface (BCI) implanted by a research laboratory at the California Institute of Technology (Caltech) provides him a fresh frontier of exploration in neuroscience.
The laboratory in which Buckwalter plays the role of a participant is managed by a renowned neuroscientist who has invested decades into the research and development of human implants. Currently, five individuals carrying long-term brain implants are under the lab’s observation. The world’s wealthiest individual holds explicit interest in using BCIs in an ‘enhancement’ capacity, with ambitions of creating consumer-based products aiming to merge human consciousness with computational machine power.
This vision relies on the evolving comprehension of our brains’ dynamics, promising advanced neural prosthetics based on these nuanced understandings, according to Andersen. The recent governmental intervention by Musk, leading to considerable staffing changes within the FDA, and impacting those overseeing clinical trials related to Neuralink, has stirred widespread curiosity. Observers wonder if certain limitations have been lifted, providing more freedom for development and implementation.
Returning to the past, we find José Delgado, a neurophysiologist in the 1960s, who technologically manipulated bulls via wireless implants, halting their movements mid-charge. Fast forward to 1973, Jacques Vidal, notably recognized for coining the term ‘brain-computer interface,’ applied non-invasive electroencephalograms (EEGs) to facilitate control of a cursor on a computer screen by study participants at the University of California in Los Angeles.
In the year 2004, history marked another milestone with Matt Nagle becoming the first paralysis victim implanted with the Utah Array, empowering him with control over cursors, ability to access and read emails, operate a television, and manipulate a robotic hand. Neuralink’s BCI claims its unique approach that encompasses robotic surgery acumen for the implant procedure, combined with full wireless enablement.
In spite of Neuralink’s unique claims, other companies provide alternative, less invasive options. The technique of planting electrode threads within the cortex that Neuralink utilizes was conceived by Philip Sabes during his tenure at UCSF, preceding his departure and subsequent co-founding of Neuralink.
Exploring the wireless realm moreover brings its own set of challenges. Given that each participant’s brain hosts unique implant positions, researchers can observe an extensive spectrum of brain functions. However, Neuralink’s wireless device compresses its brain signals due to bandwidth restrictions, while Caltech is capable of recording uncompressed, high fidelity signals, broadening their data capturing capabilities.
Although patients may find wireless BCIs advantageous from a convenience perspective, it may compromise the enrichment of brain-based knowledge that might potentially benefit future patient treatments. Recalling his past, Buckwalter jumped from towering rock formations into Pennsylvania’s Susquehanna River at seventeen, consequently injuring his neck and inflicting irreversible damage to his spinal cord.
Subsequently, he endured a year at a state hospital catering specifically to children with significant physical impairments. While several of his fellow patients completed their convalescence within a month, Buckwalter’s recovery was protracted.
However, Buckwalter didn’t let his physical adversity dampen his spirit. Regardless of his challenging circumstances, he sought out and constructed a fulfilling life that can be considered accomplished by numerous standards. He has left significant marks in the field of research, with fifteen years dedicated to scientific exploration and knowledge expansion.
Buckwalter has not only penned a widely cited paper on estrogen replacement therapy for women with Alzheimer’s diagnoses but also pioneered research into cognitive changes during pregnancy, a term referred to as ‘mommy brain.’ This groundbreaking work secured him spots on several morning news shows in the 1990s.
Additionally, Buckwalter played a pivotal role in the burgeoning online dating scene at the turn of the millennium. His contribution to foundational research for eHarmony and the design of its matching algorithm secured the site’s position as a leader in the realm of online dating.
The application of BCIs to further our knowledge of the brain is not just a scientific pursuit, but one with broader implications. It intersects a time when artificial intelligence is posing profound existential questions for us as a species.
In the pursuit of progress in the realms of neuroscience and artificial intelligence, it is crucial not to lose sight of the essence of humanity. In this brave new world that we are entering, advancements in understanding and technology have the potential to fundamentally shift our concept of ourselves and our interaction with the world around us.
In conclusion, the development of BCIs and AI represents a new frontier in technology and our understanding of the human brain. The story of individuals like Buckwalter highlights the potential benefits and challenges that these new technologies present.
While questions of ethical implications and scientific feasibility still linger, the journey towards deeper understanding of the brain and our relationship with technology offers an exciting glimpse into what the future may hold.
