Join neuroscientist Greg Gage as he works to build a machine that “reads minds” using an EEG and a machine learning algorithm. How does it work?

So this is how the EEG works. Inside your head is a brain, and that brain is made out of billions of neurons. Each of those neurons sends an electrical message to each other. These small messages can combine to make an electrical wave that we can detect on a monitor. Now traditionally, the EEG can tell us large-scale things, for example if you’re asleep or if you’re alert. But can it tell us anything else? Can it actually read our thoughts? We’re going to test this, and we’re not going to start with some complex thoughts. We’re going to do something very simple. Can we interpret what someone is seeing using only their brainwaves?

Does it work? Watch to find out.
