The white matter is the tissue present in the brain which is composed of the neurons enclosed in the myelin sheath. The presence of the myelin sheath gives white colour to the matter.
The cognitive process like the new experiences and learning ability is the result of the myelination process which forms a myelin sheath around the axon of the neuron.
The formation of the myelin sheath provides insulation and increase the speed of transmission in the neurons allows us to think and learn new things.
