WebMyelin damage causes several neurological diseases, such as multiple sclerosis. What is myelination in the brain? Myelination refers to an increase in the fatty sheath surrounding neuronal processes and fibers that increases the efficiency of electrical transmission. From: Fundamentals of Cognitive Neuroscience, 2013. WebApr 2, 2016 · Oligodendrocytes wrap neuronal axons to form myelin, an insulating sheath which is essential for nervous impulse conduction along axons. Axonal myelination is highly regulated by neuronal and astrocytic signals and the maintenance of myelin sheaths is a very complex process. Oligodendrocyte damage can cause axonal demyelination and … eastman at washington squareWebDuring adolescence, myelination and synaptic pruning in the prefrontal cortex increases, improving the efficiency of information processing, and neural connections between the prefrontal cortex and other regions of the brain are strengthened.
