Early Experiments with Telepathy

We've made progress.

"In a lab at Harvard Medical School, a man is using his mind to wag a rat’s tail. To send his command, he merely glances at a strobe light flickering on a computer screen, and a set of electrodes stuck to his scalp detects the activity triggered in his brain. A computer processes and relays the electrodes’ signal to an ultrasound machine poised over the rat’s head. The machine delivers a train of low-energy ultrasound pulses into the rat’s brain, stimulating its motor cortex – the area that governs its movements. The pulses are aimed purposely at a rice-grain-sized area that controls the rat’s tail. It starts to wag.

This link-up is the brainchild of Seung-Schik Yoo, and it works more than 94% of the time. Whenever a human looks at the flickering lights, the rat’s tail almost always starts to wag just over a second later. The connection between them is undeniably simple. The volunteer is basically flicking a switch in the rat’s brain between two positions – move tail, and don’t move tail. But it is still an impressive early example of something we will see more of in coming years – a way to connect between two living brains."
