…  When this story hit the popular press, there were hyperbolic
headlines referring to "mental time travel" and the ability to
predict what someone will be thinking about. The actual research
article is, not surprisingly, a bit less glamorous. The phrase
"mental time travel" refers to a model of memory recall in which
the areas of the brain that were activated during the mental
processing an event are re-activated during its recall. In a
sense, it was proposed that, to remember an event, parts of your
brain re-live it. The results of these experiments, which used
functional MRI imaging, suggest that this is an accurate model
of the brain's actions during recall.  The mind reading aspect
comes from the use of three categories of pictures—faces,
locations, and objects—in the recall tests. As part of the
recall process, areas of
