>'How memories are formed'
By BBC News Online's Caroline Ryan in Boston
>The different ways the brain works when it stores memories have been caught
>on camera.
Using modern brain imaging techniques, scientists have recorded the patterns
>in activity that change depending on whether memories are going to be
>stored
>or deleted.
The study was done by a team from the Massachusetts Institute of Technology
>(MIT) and reported to the American Association for the Advancement of
>Science annual meeting, which this year is in Boston.
The researchers identified a number of different brain parts involved in the
>very complex process of creating and storing memories.
Future tests
In their tests, healthy men and women were shown a list of words or pictures
>while they were scanned using functional magnetic resonance imaging (fMRI),
>which recorded activity in the brain.
They were then given a surprise quiz 20 minutes later to see what they
>remembered. Researchers could then match the brain patterns to the stored
>memories.
Professor Anthony Wagner, who led the research team, said: "Using this brain
>imaging technique allowed us to characterise the human brain while it was
>in
>the process of building new memories."
In addition to telling scientists more about how memory works, the technique
>could also one day be used to identify early signs of conditions such as
>Alzheimer's disease, where the brain's memory circuits stop working
>effectively.
Professor Wagner said: "We can then use that exact same technology and look
>for changes in these circuits in individuals who haven't been clinically
>diagnosed as having Alzheimer's disease, but you'd like to catch them as
>early as possible, and this could be a diagnostic tool.

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