The Brain
.What weighs about three pounds but has more parts than there are stars in the Milky Way galaxy? What fills the space occupied by only three pints of milk yet includes components that, laid end to end, would stretch several hundred thousand miles? What looks like an oversized walnut made of soft, grayish-pink cheese but contains the equivalent of 100 trillion tiny calculators? What, according to James Watson, co-discoverer of the helical structure of DNA, is "the most complex thing we have yet discovered in our universe"? To all four of these intriguing questions there is but one surprising answer: the human brain. This miraculous organ is remarkable in its structure, its function, and its chemical composition. What is the brain? According to Richard Restak, the human brain is the master control center of the body. The brain constantly receives information from the senses about conditions both inside the body and outside it. The brain rapidly analyzes this information and then sends out messages that control body functions and actions.  ("Brain" 561) According to Tether, the brain is divided into three main parts: the cerebrum, the cerebellum, and the brain stem. These parts, in turn, are largely made up of nerve cells, called neurons, and helper cells, called glia. Researchers have discovered that there may be as many as 100 billion neurons in the brain and a far greater number of glia, possibly as many as one trillion . Important discoveries throughout the decade of the 1990’s in molecular biology and genetics are revolutionizing our understanding of how the human brain works. Advances in imaging technology are allowing us to learn more about the human brain than ever before in human history. Keith A. Johnson and J. Alex Becker have even placed "The Whole Brain Atlas," which consists of dozens of images of the brain in normal, damaged, and diseased states, on the World Wide Web for anyone with access to the Internet to view and study. One area of the new brain research reveals that the first three years of a child’s life are crucial to the development of the brain. Proper stimulation of infants can according to Kotulak, affect the development of language, vision, brain power,aggression, emotions, touch, and education.

Every animal you can think of -- mammals, birds, reptiles, fish, amphibians -- has a brain. But the human brain is unique. Although it's not the largest, it gives us the power to speak, imagine and problem solve. It is truly an amazing organ. The brain performs an incredible number of tasks including the following: It controls body temperature, blood pressure,heart rate and breathing. It accepts a flood of information about the world around you from your various senses (seeing, smelling, hearing, touching, tasting,etc.) It handles your physical movement when walking, talking, standing or sitting. It lets you think, dream, reason and experience emotions. All of these tasks are coordinated, controlled and regulated by an organ that is about the size of a small head of cauliflower. Your brain, spinal cord and peripheral nerves make up a complex, integrated information-processing and control system known as your central nervous system. In tandem, they regulate all the conscious and unconscious facets of your life. The scientific study of the brain and nervous system is called neuroscience or neurobiology. (Robynne Boyd) We'll examine the structures of the brain and how each section controls our daily functions, including motor control, visual processing, auditory processing, sensation, learning, memory and emotion. Your brain is made of approximately 100 billion nerve cells, called neurons. Neurons have the amazing ability to gather and transmit...
