Since the 60’s, amazing discoveries in the study of the brain allowed us to get closer to understanding how the brain functions. It started with the concept of brain plasticity which proved that brain growth and development is a long life journey which debuct the misconception that brain stops growing at a certain age.
The next breakthrough was in the 90’s when it was discovered that the brain reached its full structural developmental of its basic set of synopsis around the age of 3 after which it loses half of its synopsis after that age. Still, with what is left, we develop the necessary intelligence to surpass all other species intelligent abilities.
In the last decade or so, brain scanning allowed scientists to study how the brain work in real time that helped them to understand the impact of each sensory experience on brain activities.
These discoveries made the scientist understand when synapsis are formed and enhanced following each sensual and emotional experiences. There are some strong evidences that built-in curiosity basics synapses are activated early in the childhood that entice the children to discover the world around them to make sense of it. It starts simple then complex with a boast around the age of 5 during the “why” asking stage which all children go through. I believe this resembles the qalam we are discussing in this series.
It is worth noting that the study of the brain, neurosciences, and the discoveries of the DNA are still primitive and there are a lot of work required to prove this argument and identifying the DNA strand responsible for the qalam.
