Conform unui studiu publicat astăzi în Nature, adulții ale căror creiere continuă să producă neuroni în mod eficient par să aibă o memorie și o funcție cognitivă mai bune comparativ cu cei în care această capacitate scade. Studiul a analizat probe de creier de la donatori decedați, variind de la tineri adulți până la "super înaintași" — persoane de peste 80 de ani cu memorie excepțională.

Cercetarea sugerează că aceste persoane în vârstă reușesc să mențină un nivel înalt de producție neuronală, ceea ce le-ar putea conferi avantajele cognitive de care beneficiază.
