Remembering in Different Ways

Check out the variation in patterns of brain activation among test subjects trying to recall items from a previously displayed word list. The best performer was S.C., and this subject also had the most intense activation and reproducibility in her testing 5 months later. The blue arrows indicate the right parietal area (imagery, attention), whereas the green arrows indicate more conventional prefrontal working memory areas.



We've included a snapshot from "musical imagery" in pianists for comparison. The last link below is a paper which shows that the parietal and prefrontal areas can be strengthened (and the fMRI signals more activated) with memory training involving mneumonics.
