A marathon taxes more than just muscles—it pushes the brain to its metabolic limits. New research shows that during extreme ...

How does our nervous system operate so quickly and efficiently? The answer lies in a membranous structure called myelin. Aa Aa Aa All our activities — eating, walking, talking — are controlled ...

Marathon brain” is real, a new study suggests. A neurologist explains why running hard temporarily reduces brain function.

Research published in the Journal of Neurochemistry has detailed the role of a protein, hnRNP A1, in the formation and ...

Conducting similar profiling of oligodendrocytes, she says, showed that genes associated with making cholesterol were significantly upregulated in the cells, while genes associated with myelin ...

Marathon runners experience reversible changes in their brain myelin. These findings indicate that myelin (a substance that surrounds the neurons) exhibits behavior that was previously unknown ...

Research published in the Journal of Neurochemistry has detailed the role of a protein, hnRNP A1, in the formation and stability of myelin, suggesting an important impact on neurodegenerative ...

My laboratory seeks to understand the molecular basis of myelination and myelin diseases. Myelin is a multi-lamellar sheath that invests large axons and permits rapid conduction of nerve signals.
