Your Incredible Brain
Your brain is the most complex mechanism in the world and the most influential organ of your body, enabling your mind to think, remember, love, hate, feel, reason, imagine, and analyze.[80]
The average brain weighs about three pounds and contains 12 billion cells, each of which is connected to 10,000 other brain cells - 120 trillion brain connections! Some have compared the human brain to a sophisticated computer, but technology hasn't come close to duplicating its capabilities.[80]
Your brain supervises everything you do, from involuntary actions such as breathing to the conscious decisions of your life. It controls hearing, sight, smell, speech, eating, resting, learning, prejudices, and everything else that makes you behave as you do. Scientists tell us that the brain is our most important organ because it determines the function of the other organs and systems, including the pituitary gland, heart, and nervous system. Your unique traits, temperament, and even physical growth patterns are all controlled by your brain.[80]
We have little or no conscious control over many of these traits, and scientists still disagree over the extent to which we rule ourselves. Yet most experts insist that we can regulate far more mental activity than we realize.[80]
A major portion of your three-pound brain houses your Intellect. Your intellect has phenomenal potential. Scientists tell us that the average person uses less than 10% of his brain's capability. If that is true, then most people die with 10 to 11 billion brain cells still unused.[80]
The vast majority of what we know about the intellect has been discovered during the past 100 years, yet scientists believe that even greater discoveries await us. Thinking and memory are the chief functions of the intellect, but it also affects our intuition, conscience, sexuality, and much more. Recent studies indicate a difference between the minds of men and women, providing scientific support for the traditional claim that the sexes think differently.[80]
The second significant part of your brain is what the Bible calls your "heart," your emotional center. It's not heart-shaped, but looks instead more like a walnut. Tied neurologically to every organ of your body, it activates both feeling and movement. The mind is to the emotions what food is to the body.[80]
The third characteristic of the brain is the will, which makes human beings unique from all other living creatures. No one knows where the will is located, but we suspect it resides in the brain, because it so depends on the mind and emotions. Many dying people have displayed a strong will long after most other bodily functions have ceased, but when the brain ceases to function, the will vanishes.[80]
It is difficult to imagine how such a complex organ as the human brain could have simply evolved.
