Human brain performance
Scientists have in recent years gained more insight into our most enigmatic bodies, A Brain. It has left a hole in many ancient myths and yielded surprising new knowledge. Here and on the following pages you can read about the brain, and how it among other things, control intelligence, memory.
We are becoming wiser YES. This has been the last 50 years. Scientists do not know why we - at least until recently - have become more and more talented. Some believe, however, that it depends on a better diet. Most believe that our complex society behind: around the clock, we are bombarded by influences from including television and computer so that the brain constantly stimulated. In addition, we go further in school, and that we get a better education than our father. Under 1990s the curve of intelligence, however, leveled off. Maybe because we have reached the ceiling of the biologically possible Alcohol kills brain cells
Men are smarter than women
Although fun healthy men claim that women only have four brain cells - one for each fireplace flat - so the truth is that we are equally wise, but that we have different intellectual strengths. Women are generally better than men at languages, while men are best, in solving spatial tasks as turning a cube in mind. In intelligence tests, it is virtually impossible to measure any difference between the sexes. We use only ten percent of the brain NO. Myth arose in the 1930s, when the neuro-surgeons, the electrodes on the bare brains and found that large areas apparently were passive. Modern scanning techniques, however, show that the doctors were wrong. Even ordinary tasks READING ALOUD involving multiple brain centers. On the other hand, Austrian researchers demonstrated that very intelligent people use their brain power more effectively than others. Geniuses activate only the part of the brain that are needed to solve a certain task, while the less talented can start the whole brain. Large brain is more smarter than small NO. Nor in this respect have no bearing size. Kask Lott Valens brain is six times larger than ours, but the animal is not smarter than us. Conversely, studies show that Albert Einstein's brain was 15 percent less than the average for other men. Despite its small brain was Einstein, however, the author of, inter alia, the theory of relativity. Old people remember the bad NO. Research has been done up with the myth that memory becomes obsolete as dopbeviset. On the contrary, it appears that with age we get better at remembering things, which can be expressed in words and figures, and that our ability to learn new things remains intact throughout life. The precondition is that we look to keep the brain running and looking for new mental challenges. It is however a difference between what we remember. Young hang more detail, while the elderly remember the context. Dolphins are intelligent animals OH YES. However, they are not more intelligent than, say, dogs or Baboons. We think that dolphins are intelligent because they - like people - communicating with each other using audio and cooperate to find food. There are also stories about the rescued mariners in distress and guided the ship through dangerous waters. Moreover, we know that dolphins are social and helpful animals, forming the united front against the sharks and trying to save a distressed artfrnder from drowning. Computers are dumb YES. The computers we have now is just as stupid and small monkeys. That will not, however, that condense to be, for the computing capacity developed so explosive that the computer is outdated almost before we have time to carry it out from the shop. The largest computer in 1950 was not smarter than a large insect, but now they have the best machines are the same knekapacitet like a little monkey. Many researchers track that we are already about 17 years, 2020, find ourselves in the situation that the computer is as smart as we humans, and that it has passed us by several lengths back in 2030. Skull reveals criminal NO. It was Franz Joseph Gall, who in 1796 invented frenologin, ie the doctrine that it can reveal a person's character traits by simply measuring the skull. The theory was that the brain has 31 areas, which controls a corresponding number of characteristics, and that these fields affect lens form. Thus, the specially developed characteristics to be visible as knobs on the skull. Frenologin However, there is no scientific basis, and although the theory was modern, as late as the 1930s, it has now been rejected. Even today, there are SEERESS, who claim to be able to read the skull on a människasom an open book. We find the present NO. Although we believe that we are always up with what is happening and happening around us, suggests research in that it is pure wishful thinking: in fact we limping half seconds after the event again. If, for example, we put down your finger in hot coffee, you can half seconds, before our minds realize that coffee is actually hot. The brain makes us, however, to believe that we are up to date, as it spools back this insight with a corresponding half seconds. Therefore, we incorrectly that we become aware of the hot coffee the moment we touch it
