How The Brain Works Or How It Is Connected - 1347 Words

Have you ever wondered how the brain works or how it is connected? Outside the brain may just appear to be a handful of pink and gray muscle, however, as you enter the human brain, it unveils an extremely complex circuit, connecting you with the rest of your body, the brain contains almost 100,00 miles of blood vessels and billions of cells. The brain is a library of information, remembering information and processing it as quick as 11 million bits per second (The Human Brain). The brain is a very copious system made of four lobes which dictate emotions, thoughts, skills and actions. To begin with, the brain is split into four different lobes, the Occipital, Temporal, Parietal, and Frontal lobes (Parts of the Brain). The Occipital lobe†¦show more content†¦Weighing at 2% of our body mass, the adult brain weighs 1300 grams. The chimpanzee is the closest animal relative to the human, around 98% of the DNA in our genes can be traced back to chimps (Who am I?). When it comes to the chimp’s brain it weighs 420 grams, nearly two-thirds smaller than the humans brain. The largest land animal, the African Elephant, has a brain nearly four and a half times larger at 6000 grams, which in contrast should mean they have a higher brain function, which may be true but logically we know is false. The African Elephant and other species have been around longer than the human race and should have adapted such as the human species did with technological and physical evolution adaptations. Even though our brain is not the largest, we can conclude that there is somethi ng special when it comes to the human brain.â€Å"One general law, leading to the advancement of all organic beings, namely multiply, vary, let the strongest live and the weakest die.† (Charles Darwin). We cannot fully understand why humans progress when it comes to evolution, but we can see that humans are the superior species. If our brains are not the largest, why are we superior? When the brain’s cells divide and grow at a rapid rate and cannot be controlled or replaced after they die our brain often develops a growth or tumor. There are three categories that tumors fall into benign (not
