Myelin emerges as an active regulator of brain plasticity, not only a structural insulator

MedicalXpress | mai 13, 2026

A study by Professor Carlos Matute of the EHU reinforces a paradigm shift in neuroscience: Myelin goes from being a structural element to being an active component of brain function. Published in Trends in Molecular Medicine, the study shows that myelin not only facilitates the transmission of signals, but also plays an active role in brain plasticity, in other words, the brain's ability to adapt.
