Neurologists and neuroscientists use a variety of techniques to study myelin and its role in the nervous system. Imaging technologies such as MRI can visualize myelin in the brain and spinal cord, helping to diagnose myelin-related disorders. Biochemical methods are used to analyze the composition of myelin and identify abnormalities. Additionally, animal models and cell cultures are employed to investigate the mechanisms of myelination and demyelination, as well as to test potential treatments.
