Carnegie Mellon University neuroscientist Marcel Just.

A neuroscientist at Carnegie Mellon University is translating science fiction into science fact.

And the latest developments in his work are pretty amazing.

As recently as a decade ago, CMU professor and researcher Marcel Just made headlines around the world with news that scientists could tap enhanced MRI technology coupled with sophisticated computers to determine what concrete objects a subject was thinking about.

By 2013, Just’s team had refined their work to be able to identify emotions in a similar fashion in a controlled laboratory setting. That accomplishment set legal minds on fire about the potential implications for the courts, a debate that is still going on.

Sunday night, the CBS program “60 Minutes” featured a visit to his lab to see how far researchers have come.

Using a series of computer-generated images, Just showed reporter Lesley Stahl how the brain functions in distinctly different ways when thoughts are centered on complex concepts such as faith, envy, cruelty and even suicide.

Eventually, some believe his work could lead to a map of the brain that would allow scientists to know what we’re thinking and feeling.

While science fiction has long obsessed about the power of mind reading, scientists here are trying to put such tools to work for good.

“60 Minutes” reported that Just’s team has joined with Dr. David Brent, a psychiatrist at the University of Pittsburgh, and Harvard psychologist Matt Nock on a study that will gather information on the brain activity of suicidal individuals that might help experts assess who is at risk.

We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers

We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.

We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.

We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail.
