Control Center: The Brain
The human brain has a system that can carry out many tasks at the same time. For example, because of the perfect structure of the brain, a person, while driving a car, can both adjust his cassette player and turn the steering wheel easily. Although he does several different things at the same time, he does not run into other cars or passengers. In addition, he can operate the accelerator pedal with his foot. He can understand what is said as he listens to the radio. He can continue to speak from the point where he left off. And, most importantly, he can direct all of these things in a perfect way, at the same time. In short, by means of the extraordinary capacity of the human brain, man can handle many things at the same time. What provides this harmony are the connections of the nerve cells in the brain.
Millions, even billions, of stimuli coming to the brain from the outside world are analyzed in the brain in harmony, then are evaluated and the necessary responses are given to each one. The operation of this complicated system continues to function all through one's life without any interruption. Thus, we see, hear, feel and continue our lives.
One of the most important elements constituting this perfect system in the brain is that of the nerve cells, which number approximately 10 billion. The nerve cells of the brain, unlike other cells, transmit and process information through creating and conducting small electrical currents.
The force that makes connections among cells and, therefore, harmony in the brain is found in the special structure of nerve cells. About 10 billion cells in the brain have about 120 trillion connections. And these 120 trillion connections are in just the right places. If any one of these connections was in the wrong place, the outcome would be very serious. In fact, it would be impossible for people to carry out their vital functions. Yet, such a thing does not happen and human beings, except for exceptional illnesses, lead a life which comes very naturally to them while, in reality, there are trillions of miraculous processes taking place behind the scenes.
This structure working interdependently in the brain is also,
like all the other systems in the human body, one that has
a perfect design at every stage. The reason for the brain's
performing its millions of functions without any mistake or
disorder is the fact that God, the Owner of endless wisdom,
has created it along with all its features.
