The neurological basis of personality has always been a bit of a mystery but researchers are now one step closer to understanding it. Using advanced brain scan technology, researchers were able to estimate myelination levels in different brain areas.
So what exactly is myelin? Myelin is a fatty substance that insulates nerve fibres in your brain. It speeds up information processing and it’s usually thicker in cortex areas related to perception and movement. The process of coating nerve fibres, also known as axons, with myelin is called myelination. Myelination helps protect and conduct electrical signals in the neuron.
