Professor Henry T. "Hank" Greely is quoted in a Pittsburgh Tribune-Review story on the research and evolving ability of computers to read a person's thought processes:

Hank Greely, a Stanford University law professor and chairman of the university's Center for Biomedical Ethics, said the research could be used for good causes -- such as helping a quadriplegic communicate -- or bad, such as by a totalitarian government wanting to determine its citizens' allegiance.

"We're living in the middle of a revolution, the early parts of a revolution in our understanding of the brain," said Greely, who did not participate in the research. "The extent to which we understand how our brains work ... is going to transform society.

"The time to begin thinking and talking and debating how to use this technology is now."
