Neuronal critical periods are limited phases of life during which the plasticity of neural connections is at its maximum and the development of the brain is adapted to the environment. Researchers at the Scuola Normale Superiore in Pisa and the Leibniz Institute on Aging (FLI) in Jena have discovered the role of a small microRNA (miR-29) in these learning-dependent phases of plasticity. A premature increase in miR-29 concentration in young mice blocks cortical plasticity, whereas blocking miR-29…
