  • Clues to how ‘super-agers’ retain young memories

    Bioscience Technology - 09/14/2016

    Barrett, who is also University Distinguished Professor at Northeastern University, added: “We also examined a group of regions known as the salience network, which is involved in identifying information that is important and needs attention for specific situations, and found preserved thickness among super-agers in several regions, including the anterior insula and orbitofrontal cortex.”

    Critically, the researchers showed not only that super-agers had no shrinkage in these brain networks but also that the size of these regions was correlated with memory ability. One of the strongest correlations between brain size and memory was found in an area at the intersection of the salience and default mode networks. Previous research has shown that this region — the para-midcingulate cortex — is an important hub that allows different brain networks to communicate efficiently.
