- Brain Assymetry: If you are constantly using both hemispheres of your brain, there is a sort of competition going on and brain asymmetry can result. This is important because it is thought to enable the two hemispheres to specialize and operate more efficiently. It is present in the brains of most animals.
-Brain evolution: Through out time the human brain has become bigger in size. Also man's ability to make tools has become better. So Australopithecus, very early man man, made simple tools. Then homo habilis, with a brain about twice as large as Australopithecus, created stone tools and some form of language. Homo erectus increased in brain size from homo habilis and controlled fire, made stone tools, and had a possible vocal language. And the homo sapiens neandertalis' brain increased in size as well, so did the modern human brain. Any theories about the acual devolpement of the brain cannot be acually proven beacuse you cant actually interview a homo habilis or Austalopithecus. The only real statement that can be made is the devlopment of language and the technology increased.
- Future of the Brain: Some scientists who have thought about the future of the human brain have come to the hypothesis that one day humans could have computers imbeded in them. It would be a neural implant that could think on its own. With this device humans would be able to interact with the computer-and it would respond. Only a thought would bring the answer to any question available that a computer would know. There would no longer be any need for textbooks or calculators, for all of that information would be in the implant. These are now called symbiotes, for there would be a symbiotic relationship between the computer and the human, both helping each other. Another idea for the future is having electrodes implanted in the brain so that the human will be able to control machinery by only thinking about it in their heads. Other myths suggest that with a simple thought a single person can control an electronic device halfway across the world. Cell phones will be a thing of the past as they will all be a part of this future brain. Nobody knows for sure what the future brain will be like. Another idea is that a hardware brain built with nanotechnology will stay alive, even after the physical body dies. This brain can then be placed in another body formed without a brain and the person will only need to adjust to a new body, but all of the past memories will stay the same.
