involving video games -- but have you have you ever wondered what your brain actually looked like while your playing video games? Well, feast your eyes on the image above. That's an MRI scan of New York Times writer Matt Richtel's brain that was captured while he played a simple driving game -- all in the name of science (and journalism), of course. As Richtel notes, however, that's just one example of the ways researchers are using such technology to "map the ethereal concept of attention," and scientists have turned up some other interesting findings as of late. Researchers at the University of Utah, for instance, have found that people's ability to juggle two tasks begins to drop off in their 30s and then sharply drops in their 40s, which contradicts earlier suspicions that people's ability to multitask only began to degrade when they're much older. Some other researchers are still suspicious of those findings, however, and Dr. Gazzaley of the University of California at San Diego is quick to point out that all of this research is still in the earliest stages -- he's expecting some more detailed findings next year when his team expands their tests and begin to incorporate EEG monitoring as well.
