The Brain : Documentary on the Abilities of the Human Brain
There is the most complicated object in the known universe and the most mysterious part in human being, which dominate the way we live. It is BRAIN
Nowadays, human’s brain are much bigger than our ancestor’s one- ape. With be bigger size, our brain need more energy to run. Our brain has staggering 100 billion neurons together, they could generate enough electricity for life. The neurons aren’t physically join together, there are tiny gaps. And to bridge these gaps, neurons release minute quantities of chemicals everytime- a fun chemical go-betweens.
About alcohol, it isn’t alcohol make human drunk, it’s fatty acids clog up the surface of the neurons, attack only parts of my brain including those control my speech, my mood, my memory.
A particular region of brain takes on a different responsibility from our most advanced healing abilities such as language, memory to the more basic ones like movement:
First, about cerebellul. It helps us learn new tasks and carry them automatically. The cerebellul is responsible for automatic movements, when we start , the cerebellul sends out instructions to the rest of the body, this happen without being aware of it.
Second, about visual sense, a whole quarter of oversized brain is devoted to vision, much more any other senses. Visual sense has many official distrinct elements, when combining them together, it will create one coherent view of the world.
Third, about powerful memory. Long –term memory is in front of the brain and average, brain can store a billion different items, this powerful memory originally evolved to help us navigate our way around our environment. Some people have good memory, scientists found that there no difference between them and us. The only different thing is that they have trained the memory.
Parents teaching their children is another way of passing information down the generations, through education, we learn about the world, all this knowledge is absord by the powerful human brain. The brain hardest task is how to deal with human society. Perhaps, this the main force behind the growth of the human brain.
Over years, human’s brain and body have evolved to meet more complicated challenges. We learned to manipulate tools, we made full use of visual sense and we developed a powerful memory. Up to now, we can build up a detailed picture of the brain we’ve evolved. The cerebellul is responsible for automatic movements, back of the brain for vision, a frontal cortex for memory, a particular site for language. But there is still something missing from this map. It’s that consciousness that allows us to appriciate the great things in life: love, art, science, religion, make us human. Consciousness is part of whole brain.
So far, brain map is gradually discovered, but, some questions can’t be answered and author belive that much of what make us human is SOUL.
