team of researchers from Stanford say they've created a system to "eavesdrop" on the brain, allowing them to monitor a person's brain activity while that person moves around (and thinks) in a normal environment, instead of, say, an MRI chamber. Scary! Mind-reading! Inception! BWAMMM.

No, not really: it would be tough to pull the researchers' trick off in cognito. To make it happen, the team removed parts of skull from three patients experiencing frequent, drug-resistant epileptic seizures, then attached a packet of electrodes to their exposed brains. After that, the researchers let the patients experience their stay in the hosptial as they normally would, using the electrodes to record data on the seizures, as well as everything else they did during the hospital stay, like eating or speaking.
