These Scientists Have Taken Over Mouse Brains. Is the New Method Flawless?
Scientists in Korea have just developed a new method of “mind control.” This time, they used a less invasive method based on a combination of genetics, nanoparticles, and magnetic fields.
One activation of the magnetic field was enough. The mice subjected to the experiment, equipped with nanoparticle “switches” in the brain, began to perform specific tasks. Feeding, socializing. Of course, this is not the first experiment of this type. But they have usually relied on cumbersome electrodes based on invasive surgery and limited mobility. Scientists from the Institute for Basic Science (IBS) in Korea have found another solution.

As indicated by the portal sciencealert.com, this the method, called Nano-MIND, involves directing pathways in the brain using a combination of genetics, nanoparticles and magnetic fields, which is considered a breakthrough in neuroscience. This is the world’s first technology that allows free control of specific areas of the brain using magnetic fields, the study authors point out.
The new method was inspired by optogenetics, which allows the construction of mechanisms in cells that can be easily activated by a light source. In the case of the experiment in question, the researchers integrated ion channels into the target brain cells of mice. However, Instead of providing light, the ion channels were “triggered” by a small actuator. How did this translate into research?
Scientists designed three different tests. As described by the portal scienscealert.com, the first involved receptors involved in complex feeding and reward behaviors in the lateral hypothalamus, a region located deep in the brain’s core. Monitoring the animals’ movements and food intake in and out of the magnetic field revealed significant differences that showed that it is actually possible to direct the desire to eat in mice. When the magnetic field was activated, consumption dropped by as much as half.
Similar changes were observed in experiences related to establishing relationships and parental care. The effects obviously bring hope in the treatment of mental illnesses or neurological disorders.. As always, however, we must ask ourselves whether this tool will not also be used for evil purposes.
