Chile: Pioneering the protection of neurorights

Chile is set to become the first country in the world to legislate on neurotechnologies and include “brain rights” in its constitution.

In 2021, Chile’s Senate unanimously approved a bill to amend the constitution to protect brain rights or “neurorights”. The Chamber of Deputies reviewed and approved the amendment in September that year. It is now expected that the bill will be signed into law by the country’s president.

Once the process is completed, Chile will become the world’s first country to have legislation to protect mental privacy, free will and non-discrimination in citizens’ access to neurotechnology. The aim is to give personal brain data the same status as an organ, so that it cannot be bought or sold, trafficked or manipulated.

At the same time, a constitutional reform to amend Article 19 of the Magna Carta, the country's constitution, is being considered to “protect the integrity and mental indemnity of the brain from the advances and capacities developed by neurotechnologies”.

The adoption of such a legal arsenal may seem premature in view of the development of neurotechnologies, which are still limited in their capacity to act on the human brain. But experts are already sounding the alarm and insisting on the need to legislate before intrusive applications become widespread – especially as progress in the field of neurotechnology continues to  accelerate.

In April 2021, Neuralink, entrepreneur Elon Musk’s brain-machine interface company, released a video of a monkey playing a video game after getting implants. The brain-machine interface technology used to do this is still in its infancy, but it opens the way to an infinite number of applications.

Dangerous spin-offs

It was precisely this proliferation of technological advances that prompted the Chilean Senate's Future Challenges Commissionto take an interest in neurotechnology three years ago. Following a visit by Rafael Yuste – a neurobiologist at Columbia University, New York, and one of the initiators of the BRAIN Initiative, a United States project to map the human brain – the Commission began to be concerned about the risks these advances pose to human security and free will.

While the development of neurotechnology offers hope for many patients – including those with paralysis or degenerative diseases such as Parkinson's or Alzheimer's – it could lead to the manipulation of the human brain.

“Regulations must evolve quickly,” warns Guido Girardi, senator and president of the Commission, and one of the initiators of the legislation. "There are already technologies that can directly read the brain, decipher what people are thinking and feeling, but also implant feelings that are not one’s own.”

More than the technology itself, it is the potential applications that are of most concern. “If we wait for the technology to mature, we may never be able to control it,” warns Carlos Amunátegui, professor at the law school of the Pontifical Catholic University of Chile, and one of the experts appointed by the Commission to draft the legislation.

“It would be naive to think that these advances will not translate into commercial applications,” says Pablo López-Silva, a psychologist and professor at the University of Valparaiso. “While the development of these technologies is not a problem in itself, it can cross dangerous boundaries if there is no regulation.”

Such applications, he explains, could be hacked or contain “neuro cookies” that would allow them to identify a consumer's preferences, and eventually, to implant new ones.
