Annie Ilsley, Winner of the 2023 NIMH Three-Minute Talks Competition

Annie Ilsley discusses white matter composes about half the brain and forms pathways that are essential for communication between regions. Myelination is a key, neurodevelopmental process in which a fatty sheath, known as myelin, envelops neuronal axons that form white matter tracks, acting as insulation and allowing for efficient conduction through these pathways.
