    >'How memories are formed'

    By BBC News Online's Caroline Ryan in Boston

    Using modern brain imaging techniques, scientists have recorded the patterns

    The study was done by a team from the Massachusetts Institute of Technology

    In their tests, healthy men and women were shown a list of words or pictures

    Thanx Vince. Looks like memory is being approached via bottom/up molecular
    and top/down imaging methods.
