BCI (Brain-Computer Interface): A Technology with a Long History

with No Comments

The Brain-Computer Interface (BCI) technology, also known as Brain-Machine Interface (BMI), enables direct exchange of information between the brain and an external device. Although this fascinating technology may seem like science fiction, it was not invented by Elon Musk – in fact, it has roots in decades of scientific research.

Miguel Nicolelis explains the principles of BCI and his research in the video “Welche Macht haben Gedanken? | 42 – Die Antwort auf fast alles Reupload | ARTE” starting at 18:20 minutes.

Origins and Early Developments

The foundations of BCI research were laid in the 1960s. German neuroscientist Hans Berger discovered the brain’s electrical activity in 1924, forming the basis for measuring EEG (electroencephalography) – a crucial method for capturing neural activity. This discovery opened the door to exploring how thoughts and brain waves could be measured and interpreted.

In the late 1960s and early 1970s, researchers like Eberhard Fetz at the University of Washington began conducting experiments in which monkeys controlled simple tasks through brain signals. His work laid the groundwork for controlling machines via brain activity and demonstrated for the first time that living beings could willfully alter their brain signals to influence external devices.

Miguel Nicolelis and the First Groundbreaking BCI Research

Neuroscientist Miguel Nicolelis and his team at Duke University were pioneers in modern BCI technology development in the early 2000s. In 2003, Nicolelis demonstrated that monkeys with implanted electrodes could control robotic arms using only brain signals. The monkey, named Aurora, became a notable figure in research, as she could play simple video games with just her thoughts. This work proved that it was possible to use brain signals to control computers and machines, and Nicolelis’ research is still considered groundbreaking.

The Role of Neuralink and Elon Musk

Neuralink, the company founded by Elon Musk, is one of the newer players in BCI development, but Musk’s involvement has brought increased public attention to the field. Established in 2016, Neuralink aims to revolutionize human-machine communication through new implant techniques and to advance the miniaturization of the technology. Neuralink’s approach focuses on using implanted electrodes that are less invasive and more efficient, with the long-term goal of treating neurological diseases or assisting people with paralysis.

Neuralink’s advancements lie in the miniaturization and improvement of BCI implants, along with the development of a robot that can precisely implant these electrodes. Musk and Neuralink’s vision goes beyond medical applications and ultimately aims to link the human brain more closely with artificial intelligence.

BCI Today and in the Future

Today, BCI research already has applications in treating neurological disorders, such as epilepsy and Parkinson’s, and allows paralyzed patients to control prostheses. However, everyday BCIs still face challenges such as the long-term safety of implants, ethical considerations, and improving signal quality.

The development of BCI is thus the result of a long history with contributions from many scientists and research teams. While Neuralink has drawn more attention to the field and is contributing to its advancement, the technology’s foundations and applications are the work of pioneers like Hans Berger, Eberhard Fetz, and Miguel Nicolelis.
