Where is the frontier of neurotechnology today?

Consider this experiment: two healthy female mice are idly sitting in a chamber. Suddenly, magnets around the chamber are activated. The female mouse marked with green suddenly rushes to the distant mouse pups and brings them to safety. The other female mouse, marked with red, remains indifferent.

Scientists have triggered a specific behavior pattern—maternal care—in the "green" mouse. This was achieved without any cables or electronics attached to its head, solely using a magnetic field. They could induce other behaviors as well, depending on which neurons were targeted. Now, researchers can gather rodents in one place and simultaneously activate or deactivate various behavior patterns in different individuals.

There's no need to worry yet—turning a human into a zombie using magnets is still far from reality. However, we are now a step closer to treating brain diseases. This method allows for non-invasive and selective regulation of specific neural circuits' activity.
