Do Brain Implants Change Your Identity?

Today, at least two hundred thousand people worldwide, suffering from a wide range of conditions, live with a neural implant of some kind. In recent years, Mark Zuckerberg, Elon Musk, and Bryan Johnson, the founder of the payment-processing company Braintree, all announced neurotechnology projects for restoring or even enhancing human abilities. As we enter this new era of extra-human intelligence, it’s becoming apparent that many people develop an intense relationship with their device, often with profound effects on their sense of identity. These effects, though still little studied, are emerging as crucial to a treatment’s success.

The human brain is a small electrical device of super-galactic complexity. It contains an estimated hundred billion neurons, with many more links between them than there are stars in the Milky Way. Each neuron works by passing an electrical charge along its length, causing neurotransmitters to leap to the next neuron, which ignites in turn, usually in concert with many thousands of others. Somehow, human intelligence emerges from this constant, thrilling choreography. How it happens remains an almost total mystery, but it has become clear that neural technologies will be able to synch with the brain only if they learn the steps of this dance.

For the great majority of patients, deep-brain stimulation was beneficial and life-changing, but there were occasional reports of strange behavioral reactions, such as hypomania and hypersexuality. Then, in 2006, a French team published a study about the unexpected consequences of otherwise successful implantations. Two years after a brain implant, sixty-five per cent of patients had a breakdown in their marriages or relationships, and sixty-four per cent wanted to leave their careers. Their intellect and their levels of anxiety and depression were the same as before, or, in the case of anxiety, had even improved, but they seemed to experience a fundamental estrangement from themselves. One felt like an electronic doll. Another said he felt like RoboCop, under remote control.

Gilbert describes himself as “an applied eliminativist.” He doesn’t believe in a soul, or a mind, at least as we normally think of them, and he strongly questions whether there is a thing you could call a self. He suspected that people whose marriages broke down had built their identities and their relationships around their pathologies. When those were removed, the relationships no longer worked. Gilbert began to interview patients. He used standardized questionnaires, a procedure that is methodologically vital for making dependable comparisons, but soon he came to feel that something about this unprecedented human experience was lost when individual stories were left out. The effects he was studying were inextricable from his subjects’ identities, even though those identities changed.

Many people reported that the person they were after treatment was entirely different from the one they’d been when they had only dreamed of relief from their symptoms. Some experienced an uncharacteristic buoyancy and confidence. One woman felt fifteen years younger and tried to lift a pool table, rupturing a disk in her back. One man noticed that his newfound confidence was making life hard for his wife; he was too “full-on.” Another woman became impulsive, walking ten kilometres to a psychologist’s appointment nine days after her surgery. She was unrecognizable to her family. They told her that they grieved for the old her.

The Military Is Funding Ethicists to Keep Its Brain Enhancement Experiments in Check

The Department of Defense has already invested in a number of projects to which the Minerva research has relevance. The Army Research Laboratory, for example, has funded researchers who captured and transmitted a participant’s thoughts about a character’s movement in a video game, using magnetic stimulation to beam those neural instructions to another person’s brain and cause movement. And it has supported research using deep learning algorithms and EEG readings to predict a person’s “drowsy and alert” states.

Evans points to one project funded by Defense Advanced Research Projects Agency (DARPA): Scientists tested a BCI that allowed a woman with quadriplegia to drive a wheelchair with her mind. Then, “they disconnected the BCI from the wheelchair and connected to a flight simulator,” Evans says, and she brainfully flew a digital F-35. “DARPA has expressed pride that their work can benefit civilians,” says Moreno. “That helps with Congress and with the public so it isn’t just about ‘supersoldiers,’” says Moreno.

Still, this was a civilian participant, in a Defense-funded study, with “fairly explicitly military consequences,” says Evans. And the big question is whether the experiment’s purpose justifies the risks. “There’s no obvious therapeutic reason for learning to fly a fighter jet with a BCI,” he says. “Presumably warfighters have a job that involves, among other things, fighter jets, so there might be a strategic reason to do this experiment. Civilians rarely do.”

It’s worth noting that warfighters are, says Moreno, required to take on more risks than the civilians they are protecting, and in experiments, military members may similarly be asked to shoulder more risk than a regular-person participant.

DARPA has also worked on implants that monitor mood and boost the brain back to “normal” if something looks off, created prosthetic limbs animated by thought, and made devices that improve memory. While those programs had therapeutic aims, the applications and follow-on capabilities extend into the enhancement realm — altering mood, building superstrong bionic arms, generating above par memory.

Neurotechnology, Elon Musk and the goal of human enhancement

“I hope more resources will be put into supporting this very promising area of research. Brain Computer Interfaces (BCIs) are not only an invaluable tool for people with disabilities, but they could be a fundamental tool for going beyond human limits, hence improving everyone’s life.”

He notes, however, that one of the biggest challenges with this technology is that first we need to better understand how the human brain works before deciding where and how to apply BCI. “This is why many agencies have been investing in basic neuroscience research – for example, the Brain initiative in the US and the Human Brain Project in the EU.”

Whenever there is talk of enhancing humans, moral questions remain – particularly around where the human ends and the machine begins. “In my opinion, one way to overcome these ethical concerns is to let humans decide whether they want to use a BCI to augment their capabilities,” Valeriani says.

“Neuroethicists are working to give advice to policymakers about what should be regulated. I am quite confident that, in the future, we will be more open to the possibility of using BCIs if such systems provide a clear and tangible advantage to our lives.”
