The research conducted by Dr. Folcher and his team presents an intricate experimental design that explores the concept of mind-controlled gene expression—a complex and innovative idea. The experimental process begins with a human participant who wears an electrode headset and sits in front of a computer. While engaging in a simple game or observing a serene landscape, a Bluetooth device transmits the participant’s brain signals to a controller, which modulates an electromagnetic field based on the participant’s relaxation level.
At this point, a rodent participant enters the experiment. As the mouse navigates through the electromagnetic field, a wireless implant embedded in its skin emits near-infrared light, activating a specially engineered population of cells. This activation initiates a series of biochemical reactions that lead to the production of a protein known as secreted alkaline phosphatase (SEAP). Essentially, when you relax, the mouse benefits from increased protein production.
To put it in the authors’ words, “An electroencephalography (EEG)-based brain–computer interface (BCI) processes mental state-specific brain waves to program a wireless-powered optogenetic implant containing designer cells engineered for near-infrared light-adjustable expression of the human glycoprotein SEAP.” Quite the mouthful, isn’t it?
Returning to the activities for the human participant, the authors state, “To achieve the mental state of concentration, the subject played the computer game Minesweeper, and for meditation, subjects were instructed to breathe deeply while viewing a landscape image on the LCD screen.” Here, one might wonder about the relevance of using such classic technology—are researchers still relying on Windows XP? The proprietary algorithms of the headset allow for the calculation of a meditation index, although it is necessarily limited in its sophistication. Moreover, the cells producing SEAP were not mouse cells, but rather human cells deliberately inserted into the mouse’s implant. In essence, the mouse functions similarly to a petri dish.
While the experiment is certainly attention-grabbing, it represents incremental progress rather than groundbreaking innovation. Nonetheless, the combination of electrical signals with genetic manipulation through electrogenetic devices could be a significant advancement in medical science. According to Dr. Folcher and his colleagues, “When connected to brain activities, such electrogenetic devices offer mind-genetic interfaces that could enhance modern electronic-mechanical implants, including heart and brain pacemakers, cochlear hearing aids, eye prostheses, insulin-releasing micropumps, and bionic limbs.”
This may not be the most direct approach, but utilizing the brain’s rich electrical data could hold promise for treating conditions like epilepsy. If anything, this research emphasizes the potential for imaginative applications of this data.
The Nature Communications paper reflects a growing trend in neuroengineering. Recent studies from prestigious institutions have reported “brain-to-brain interfaces” that enable data communication between different brains. One study demonstrated that a rat’s performance on a task could influence another rat’s choices, while another reported that a human subject’s response to a strobe light could elicit a reaction in a rat.
In contrast, some contemporary buzzwords—such as robotics, data, and 3D printing—are immediately relevant, particularly in the field of prosthetics. The distinction lies in how effectively these concepts translate into real-world applications.
While some researchers may pursue advanced techniques simply because they can, rather than due to pressing needs, there is always value in exploration. Serendipity plays a crucial role in scientific discovery. For instance, a well-known anticoagulant was initially developed as a rat poison, and a popular medication intended for hypertension revealed unexpected benefits. The innovative electrogenetic system described by Dr. Folcher’s team may one day contribute to therapies for neurological disorders—or perhaps lead to a new medical breakthrough.

In summary, while the research on mind-controlled gene expression may seem fanciful, it represents a step forward in combining brain activity with genetic manipulation. The implications for modern medicine could be far-reaching, paving the way for innovative treatments and enhanced medical devices.
