The Mysterious Brain
When you refer to your brain, you should probably say "brains".Most modern scien-tists studying the brain have con.eluded that there are three major parts of our brain,-that each is separate from the others, and that each has its own function and different proces-ses.
Brain 1 includes the spinal cord(髓脑), which sits directly on the top of the cord, and the middle section of the brain.It includes the controls for involuntary functions like breathing and digestion. Brain 2 is an area surrounding Brain 1.In this second brain are the various glands(腺)located in the brain, such as the pituitary(垂体)and amygdala(扁桃体). Scientists studying Brain 2 are convinced that human emotions such as excitement, fear, and love are centered here, as well as the senses of taste and smell.Memory and learning are also controlled by Brain 2.Brain 3 is the neo-cortex(新大脑皮层), the thick covering that surrounds the top and side portions of the brain.This is the "gray matter" we often think of when we speak of the brain.Only the higher orders of animals have Brain 3, and none is as highly developed as the human neo-cortex.Brain 3 sends:informa-tion from the other two brains to the body and receives data from the body.It is Brain 3that makes us fully human.Brain 3 allows us to stand erect(直立), to see, to speak, to write, to use symbols and tools, and to remember.Brain 3 also acts as a unifying control of the other two brains.As scientists continue to study the brain, they discover specific
areas that control particular functions of the body and particular emotions.

Today there are more birth control options 58 , but overpopulation and unwanted pregnancies remain worldwide 59 .Having more children than one can support may lead 60 poverty, illness, and high death rates for babies, children, and women.
