Computer algorithm, MRI used to tap memory  A computer
algorithm, functional Magnetic Resonance Imaging (fMRI), and
neuroscientists working together have been able to identify what
people are remembering by measuring blood flow levels, according
to new research out of the University College London.  First, a
group of 10 volunteers (average age 21) was shown three very
short (as in 7 seconds) films, each of a woman on a city street
doing a simple task, such as mailing a letter. Then, each of the
volunteers was placed inside an fMRI scanner and asked to recall
