We all have heard the proverb “practice makes perfect” a million times. But how does this proverb fit accurately in practicality? Is it possible that continuous practising is making us perfect for our entire life? In this article, we have tried to lay down the practical approach of “practice makes perfect”. We will tell you many neurological that you might not aware of!

Learning To Rewire Our Brains

Learning a new talent, whether it’s programming, phone customer assistance, chess, or executing a cartwheel, alters our brain’s wiring. In other words, the brain does not “harden” around age 25 and remains solid for the rest of our lives. 

While certain skills, like language, are easier for kids to acquire than adults, research shows that even older individuals may experience substantial changes in their neurocircuitry.

Working Of Nerve Signal

Neurons are the brain’s fundamental cellular building components. An axon is a lengthy “cable” that stretches out and interacts with other neurons’ dendrites. The brain sends nerve impulses, which are electrical charges that move down the axon of a neuron, ultimately reaching the next neuron in the chain.

Imagine a row of dominos placed tightly together: a neuron firing is like a domino falling. This happens until the nerve signals reach their goal. These rapid-fire firings occur.

Effect Of Myelination On Nerve Impulses

Our brains are commonly referred to as “grey matter” since they seem largely grey. Our neuron cell bodies are that hue. But there is also “white matter” that makes up roughly half of our brains. That white material is myelin, a fatty layer that wraps many of our neurons’ lengthy axons. 

In order to reach the next open place on the axon, scientists discovered that myelination speeds up and strengthens nerve impulses.

What Causes The Growth Of Myelination?

Myelination occurs spontaneously, mostly in infancy. Young children are like myelin-producing machines, constantly absorbing information. We can keep adding myelin to our axons as we age, but it takes longer and more work.

Scientists think two non-neuronal (glial) cells in the brain help create new myelin. The first is an astrocyte, a glial cell. The astrocyte releases chemicals that encourage the second cell (known as an oligodendrocyte) to form myelin, which wraps around the axon.

In other words, by writing every week, shooting jump shots on the basketball court, or playing Call of Duty, we train our neurons. This causes the glial cell pair to myelinate the axons, enhancing the signal speed and strength.

Myelination Neuron Works Better

Brain scans of experienced musicians provide solid evidence. A lot of studies have been done on how musicians’ brains vary from regular people’s. One research employed Diffusion MRI, a non-invasive brain scan that provides information about tissues and fibres within the scan area. 

The research found a link between childhood and adolescent piano playing and white matter density in areas of the brain associated with finger motor abilities, visual and auditory processing, and others. Most importantly, there was a clear association between practice hours and white/myelin matter density.

What occurs when myelin is absent is another major factor in its favour. Demyelination is linked to MS and other neurodegenerative illnesses, causing symptoms including loss of dexterity, blurred vision, bowel control loss, and overall weakness and exhaustion. This shows that myelin helps us maximise our brain and body functioning.

Practice Strengthens Myelination

Myelination occurs when brain circuits function together better over time. You need to practise regularly and obtain plenty of feedback to enhance your performance. So, we can say that practice makes one perfect!
