Once asleep, a new list of words was tested on participants to ensure that the brain had to work out the meaning of the words before classifying them using the buttons. Their brain activity showed they continued to respond accurately, the researchers said, although it happened more slowly.

EEG-based interrogation of sleeping people?!
I'm wondering the same thing. The article is rather vague about how they gave "a new list of words to participants" while they were sleeping...
If OpenBCI ships soon, people can try this at home :) https://www.kickstarter.com/projects/openbci/openbci-an-open...
You can preorder now and they'll ship soon. The consensus is that they're a little pricey, though:
