The research conducted by Dr. Folcher and colleagues resembles a complex Rube Goldberg machine—let’s be honest, the idea of mind-controlled gene expression is hardly a simple one. Here’s how the experiment unfolds: In the initial phase, a human participant dons an electrode headset and sits in front of a computer screen. While she engages in a game or admires a tranquil landscape, a Bluetooth receiver transmits her brain signals to a controller, which adjusts an electromagnetic field based on her relaxation levels. Sounds wild, right?
At this point, a rodent participant enters the scene, and things get even more bizarre. As the mouse meanders through the electromagnetic field, a wireless implant in its skin emits near-infrared light, activating specially designed cells that have been implanted for this purpose. This activation triggers a series of chemical reactions that lead to the production of a protein known as secreted alkaline phosphatase (SEAP).
In simpler terms, the human participant focuses, and the mouse produces more protein. Or, as the researchers put it, “An electroencephalography (EEG)-based brain–computer interface (BCI) processes mental state-specific brain waves to program a wireless-powered optogenetic implant containing engineered cells that express the human glycoprotein SEAP in response to near-infrared light.” Quite the mouthful!
Now, let’s circle back to that computer game and the serene landscape. According to the authors, to achieve a state of concentration, the human participant played Minesweeper, while during meditation, she was instructed to take deep breaths while looking at a still image of a landscape on the screen. (So many thoughts! Is Minesweeper still a thing? What does meditation really mean? And what was that landscape like?)
The headset uses proprietary algorithms to create a “meditation index,” which is, let’s face it, a pretty rudimentary metric. The cells responsible for producing the protein weren’t even mouse cells; they were human cells placed in the mouse’s implant. Essentially, the mouse functioned more like a petri dish than a living organism. While impressive, the experiment ultimately represents a collection of small advances rather than groundbreaking discoveries.
However, the concept of merging electrical signals with genetic manipulation—an electrogenetic device—could significantly enhance modern medicine. As Folcher and his team state, such devices could create mind-genetic interfaces that introduce a new dimension to advanced electronic-mechanical implants like heart pacemakers, cochlear implants, and bionic limbs.
Perhaps it’s a stretch, but a Rube Goldberg machine does complete simple tasks in unnecessarily complicated ways. Mind control might not be the most efficient answer here, yet harnessing the brain’s electrical signals could be invaluable for treating conditions like epilepsy. If the researchers are onto something, it’s about being creative with data manipulation.

The Nature Communications paper adds to a growing list of captivating neuroengineering studies. Recently, teams from Duke and Harvard Medical School explored “brain-to-brain interfaces” that facilitate data sharing between different brains. In one study, a rat’s actions influenced another rat’s decisions, while in another, a human’s response to a strobe light caused a rat to twitch its tail.
More recently, researchers at Washington University successfully established the first human brain-to-brain interface, translating one gamer’s intent into actions on a touchpad for another. These are indeed baby steps.
Some buzzwords, however, have immediate applications: robotics, data, and 3D printing are at the core of modern prosthetic science. The key difference lies in the practical translation into real-world applications.
A mentor once told me that scientists may pursue human cloning simply because they can, not necessarily because it’s needed. I can geek out over the latest brain-to-brain developments or mind-controlled gene manipulations, but sometimes I wonder if these studies offer solutions to problems that don’t actually exist.
Nevertheless, there’s room for serendipity in science. One of the most commonly prescribed anticoagulants was initially developed as rat poison, and a well-known little blue pill was designed to treat hypertension before its unexpected side effect was discovered. Within Folcher and his colleagues’ imaginative electrogenetic system, we might uncover solutions for various neurological disorders—or even the next big breakthrough in sexual health. Who’s to say what’s sexy or not?

Summary
In summary, the realm of neuroengineering holds promise through complex experiments, such as those by Dr. Folcher and his team, which link mind control with genetic expression. While the research is flashy and intriguing, it often results in incremental progress rather than revolutionary breakthroughs. From exploring brain-to-brain communication to the potential for innovative medical applications, the journey of scientific exploration continues to unfold, leaving room for unexpected discoveries.
