BRAIN DEVELOPMENT AND BEST LEARNING AGE FOR CHILDREN
This article discusses the best learning age for the children, brain development including brain wiring and nervous tissue growth, importance of development of both sides of the brain.
For years, scientists have known that what happens – or doesn’t happen – during the first few years makes a big difference in a child’s later life, and that babies who do not get enough love and attention in infancy are less likely to be well-adjusted adults.
Thanks to brain imaging technologies, we now have a clearer understanding of how the brain functions, both before and after birth.
Two most important factors related to development of the brain and ability to learn are
1. Brain and Nervous tissue growth
2. Development of both sides of the brain which are discussed below
Brain and Nervous tissue growth
Wiring the Brain
A baby is born with about 100 billion neurons, the basic brain cells responsible for all major functions that happen in the body. Neurons exist throughout the central nervous system. Thinking, feeling, breathing, walking, and all other functions in the brain happen because these cells communicate. The number of neurons remains nearly constant from birth on, but the number and complexity of connections among neurons changes dramatically throughout the child’s life.
During the first year or two, neurons make many more connections than the baby will use. The developing brain is a little like a fertile garden. When we plant a garden, we plant more seeds than needed to ensure that some of them grow and thrive. When too many seeds sprout, there is not enough room for the healthiest plants to thrive. By weeding out some plants, we allow more room for the crops to grow. The brain has a similar “weeding” process, called pruning. Pruning is a normal part of brain development that creates more space for the most important networks of connections to expand and helps the brain conduct signals more efficiently.
Variation of Nervous tissue growth rate with age
According to the analysis on the development of nervous tissues, the development and growth of the nervous tissues will happen from 4 to 6 years old at the fastest pace and the progression will slow down after 12 years of age, when growth has reached to 75 % levels.
During juvenile period, these cells will grow up to 90 % of an adult or in other words, the liaison net of the nervous tissue will reach to 90%.
The greatest growth of human brain happens during the age from 4 years to 14 years. During this period, the frequency of brain wave increases gradually from Theta (relaxing stage) to Alpha level (relaxing but conscious). Children in Alpha level have plentiful imagination and quicker learning ability.
As they grow older into their juvenile age (the Beta level, the sober period), thought will become more complicated and rational, and they will mainly think with their left brain.
Importance of development of both sides of the brain
The relativity theory introduced in 1905 and 1916 by Einstein had shocked the science circles. He illustrated the relativity theory as an outcome of an idea. He used his right brain to create an amazing journey of thought and use his left-brain to develop a set of mathematical theories to explain the fairyland he saw.
The drawings, composition, lines and model in rough draft of Piccaso have shown the mathematical and geometrical concept.
These proved that there are hidden potential of science and arts in every brain, the only difference is that both brains are not equally developed, otherwise this will double out the network growth progress.
Control of different organs
A lot of physiological organs of the human body are divided in to right and left parts. Some of them appear symmetric on the surface, but the function is not symmetric at all. For instance, the right and left hands are different in strength and skill, so is the visual sensitiveness of the right and left eyes. For the same reason, the function of the right and left hemisphere of the brain is not symmetric either.
The different cognitive forms of the two hemispheres are mutually complementary and co-operative and develop harmoniously, making up the whole function of the human brain.
“The theme to emerge from this is that there appears to be two modes of thinking, verbal and nonverbal, represented rather separately in the left and right hemisphere respectively and that our education system, as well as science in general tends to neglect the nonverbal from the intellect. What is come down to is that modern society discriminates against the right hemisphere.
Need to train both sides of brain to train together
To give equal rein to the overall intelligence of the cerebrum, both the right and left brain must be trained at the same time. The creativity will at its greatest only when both brains are communicating and co-operating with each other. The creativity function from right brain need to be boosted by the information stored in left brain, whereas the mathematical and physical abilities must work together with the space perception from the right brain to become an excellent scientist, engineer, literati, designer and business man.
Therefore, as a parent to you children, in order to explore and enhance the children’s intelligence, the best learning time for your children is the age before 15 and development of both sides of brain is very important.
