the key to uniform conduction time in the brain

Some neural fibers have as many as 100 layers of myelin.Others only have a few.And fibers with thicker layers of myelin can conduct signals 100 times faster or more than those with thinner ones.Some scientists now think that this difference in myelination
could be the key to uniform conduction time in the brain,
and consequently, to our mental synthesis ability.A lot of this myelination happens in childhood,so from an early age,
our vibrant imaginations may have a lot to do with building up brains whose carefully myelinated connections can craft creative symphonies throughout our lives.
