Magnetism is often at the center of scientific discovery and innovation. Continuing this trend, researchers at the University of Buffalo have successfully used our favorite physical phenomenon to literally control the brains of lab mice. If you’re a little put off or creeped out by this technology, you’re probably not alone. It sounds like something out of science fiction. You can just picture the mad scientist in his lab, assembling an army of mind controlled subject, ready to do his bidding. How Does Magnetic Mind Control Work? Using a technique known as magneto-thermal stimulation, scientist can essentially recreate a digital, interactive map of a mouse’s brain. Basically, tiny doses of magnetism and heat target neurons within the brain. Targeting the right neurons can even manipulate behavior. Just as the mice running around the maze. Scientists are able to click a button, sending a wireless signal from a computer to right to the mouse’s mind. But hey, at least the mouse finds the cheese a bit faster, right? Before you run out to buy a tin foil hat, it’s important to note that this technology isn’t as precise as you might think. In other words, while this magneto-thermal stimulation is able to affect a mouse’s behavior, it has its limits. So far, the Buffalo team has only been able to prompt mice to run, stop, and turn around. The science behind this mind control is surprisingly straightforward. Nanoparticles are injected into the mouse’s brain (ouch!). These microscopic pieces of technology are then programmed to latch on to neuroreceptors in the brain. From there, it’s a simple matter of hooking the transmitters up to a wireless signal like you would a remote control car. Neat, huh? Has Science Gone Too Far? While there is always the risk that an evil supervillain might discover the secrets of this technology, the practical applications are far less scary. While the testing show that neurons in the brain can be manipulated to make teeny little rodents move whatever way you want, the hope is that this technology could one day help people suffering with various brain disorders. The research is still in its infancy and no one is sure if it will ever get to human tests. If it does, we’re hoping people will want to buy a lot more magnets!
