>'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
Using modern brain imaging techniques, scientists have recorded the patterns

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

They were then given a surprise quiz 20 minutes later to see what they

Professor Anthony Wagner, who led the research team, said: "Using this brain

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

Professor Wagner said: "We can then use that exact same technology and look

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