>For example, a typical question would be to ask what is 8 minus 6. A 19-year-old American man was able to respond by moving his eyes left-right, left-right — two times — to signal "2." Researchers asked the question again, and he moved his eyes the same way two times again.

I’d have to read the paper but color me skeptical. Moving eyes back and forth twice while sleeping is not exactly a clear signal of anything.
