Telepathy Is Real

(Inside Science) -- Now, I don’t want to alarm anyone, but telepathy, the act of transferring thoughts into someone else’s head is now real. As in, published-in-academic-papers real. People have now telepathically communicated with each other, monkeys have solved problems as a connected hive mind, and humans have even been given telepathic control of a rat. So, how exactly did we do it? The brain transmits messages as electrical signals through nerves. But we can’t just connect everyone’s heads through a giant web of nerves -- even if we could, it would be impractical. But we can read the electrical activity from brain cells with electronic devices. Then transmit the signal, like we do the internet, and turn it back into brain cell activity at the other end. Unfortunately, this is where it gets tricky. First, how exactly do you read brain activity? Implanted electrodes can do it -- they sense the change in electrical currents as brain cells activate. But unless you fancy having complicated surgery to cove
