Recreating lost memories

A super-interesting, albeit super-technical, conversation about a new study that might help people who suffer from different kinds of memory loss, such as Alzheimer’s {talk of the nation/science friday}.

A recent study has pinpointed key molecules involved in the formation of long-term memories. Scientists at the University of Pennsylvania studied patterns of gene expression in mice to determine how the brain stores information that can be recalled months or even years later.

And the results of the study […] are part of a growing body of research that looks at how so-called epigenetic mechanisms where the body’s way of regulating genes may influence our ability to form memories.
