After hundreds of thousands of years to our existence on this blue planet and colonization, we discovered quite a bit of information about it, and most importantly we have discovered a lot about ourselves, we have been able to know our bodies are accurate and detailed and we will reach a more accurate biological processes that take place inside and Racbnaha closely, we realized the disease and learned how the drug-making, and understanding of food and its role in the body is water, we realized stages of growing up starting from the sperm through to old age, but in spite of all this progress and the knowledge that we have made there are still some simple questions that we did not find her answers Court after.
Pain
Pain is a feeling uncomfortable but common among all human beings, it is one of the first things that we face in our lives, when all of a sudden are Antzaana from the wombs of our mothers, as it would be the last thing we face in life also when it comes time to our departure. But what precisely is the pain? And how it happens? Why do we feel? Are we all feel the same way or varies from one person to another? If these questions Djatlk more attention to this issue and to feel sad as you can not answer, do not worry because the science and scientists were not able to answer as well. If you suffer from chronic pain may find little solace in the fact that scientists and doctors can not understand, in fact, the experts can not agree on what the pain until the moment, the pain is complex and defies our ability to find a clear definition to him, more than just nerve impulses or Tenbegat pain sensory, pain complex of feelings and emotions, cultures and spiritual and sensual experiences and beliefs mixture. At the official site of the American Academy of Pain Management and treatment you will find their answer to a question what pain is as follows: "feel uncomfortable and emotional and unconscious response to that sense."
One way to classify pain and possibly overcome it is to differentiate between chronic pain and Chronic pain sharp intraday Acute. Intraday pain is what it feels like when they hit the hammer your finger instead of the nail or when sprain your ankle or when burning part of your body, while chronic pain is a long-term persistent pain and more frustration, may occur as a result of an injury or a viral infection in the nerves or nerve damage to the joints and atrophy and degeneration of the bones. One of the types of chronic pain called Neuropathic and nerve damage occurs as a result and not the result of physical injury that led to it, and there are recent studies suggest that this pain can also be transmitted through other nerve is damaged. Scientists also differentiate between pain lotion (Strike with a hammer on your finger deliberately to receive sense) and between automatic or spontaneous pain who do not find a clear reason externally. Acute pain is often intraday lotion, any external cause him clear, but chronic pain may be a lotion or automatically. Chronic pain resulting from automatic pain may continue for long periods without interruption and looks like a burning sensation or may be spotty and looks like a sense of challenge or acupuncture (Yes, that's what most of us feel from time to time).
At present, scientists are close to understanding the nature of the pain by analyzing the types of nerve fibers that you are moving, and how to access those signals to your brain and how to deal with your brain to it, the nerves in our bodies play a very important is that you tell us when there is a risk that such approach the hot surface or when the body wants to rest or treatment. Thousands of nerve endings responsible for pain can be found in a very small space in your thumb or spine or anywhere else in your body. There are many kinds of nerves which feels cold, including what feels heat or pressure or pain, and those responsible for pain called Nociceptors and can be found in abundance in the limbs and fingers where there are frequent injuries, and release these nerve signals toward the spine and when it becomes cause pain strongest increase the speed and the intensity of the signals that you send. In the spinal cord, these electrical signals cause the secretion of chemicals called neurotransmitters Neurotransmitters and activate other neurons working to address and send that information to the brain, and depending on how well reasoned pain intensity is determined by the speed at which will be out of that information is sent to the brain to take the appropriate response.
Pain feel chronic or momentary type is likely that it depends on the nerve responsible for transmitting pain nociceptive that we have mentioned, which carry larger cells pain signals more quickly to the brain and cause a feeling of acute pain or twitching intraday, while causing small cells or high in pain cells continuous unbearable and we can not afford. The treatment of pain signals in the hypothalamus region of the brain thalamus and hypothalamus is referring to the transfer of three places, namely:
Somatosensory cortex (physical sensation): crust or the bark of the brain from the physical sense Almsawolh
Limbic system (emotional feeling): the limbic system responsible for emotional feeling
Frontal cortex (limbic system): frontal cortex
The brain then take the appropriate action to move away from the source of the pain or eliminate it, it has secreted substances to relieve pain, such as endorphins endorphins. In the case of chronic pain, which does not have a clear reason in most cases, it is more complex and not easily understood.
Starting from scientists who study pain and researchers who design drug for treatment and doctors who prescribe the drug for you, one of them can not even agree on a single definition of the meaning of pain. It already puzzling, and to clarify to take the case of fibromyalgia as an example, which is a medical condition that best describe her is "everything hurts" There is no tests can show whether you are infected by, not a blood test or scan of the brain radiotherapy can confirm that, So how you are diagnosed with this case? In fact you have to fill a certain questionnaire and answer the questions, in the case of a mother can not be described in different parts of the body and the doctors can not diagnose it foretells injury to fibromyalgia, otherwise you take the acquisition satanic and space objects into account.
There are some drugs that the Food and Drug allowed by the Organization as a remedy for this situation because it seemed to offer some help to the injured, but no one knows why or how or whether the condition of the foundation. There are some very sophisticated techniques used by some doctors noted a difference in the images private overwhelmed brain scanning with fibromyalgia, but there is no fixed difference between the patients can be relied upon and therefore can not be any doctor to look at your brain to tell you that you have that situation, nor can any doctor to determine the amount of pain suffered; because we are still Nokhadd first steps to learn how to discover the pain in brain activity. At present there is no medical way to know the feelings or the amount of pain suffered by a person only through his question.
Yawn
Yawning is one of the most amazing and puzzling things for scientists for two main reasons: first, that yawning does not seem to serve a particular purpose. If you feel the desire to yawn and you rein in what will happen? Is disorders will develop? Is Sttazb of pain? In fact, nothing will happen. The second reason, which researchers pay to the confusion is the infectious nature of the yawn, if you Baltthaab in front of any one Staatarih desire to yawn, too, is not only among humans but extends to other animals such as monkeys and dogs were yawning these animals if they saw a man yawns in front of her, too, and it is not unlikely Now may be just yawned reading of the word yawn several times.
Of course there are explanations for the command, that ye may Qrotamoha in the books of primary school or on the Internet but they are all hypotheses is uncertain, for example, that the low level of oxygen in the blood cause a yawn to collect more oxygen, but recently turned not to the validity of this hypothesis and yawning in fact reduces connecting the amount of oxygen to the body, which is logical, in fact, you do not see athletes stop to take a break from yawning They are in desperate need of oxygen during exercise. Other hypotheses circulating that yawning is a way the body to control the degree of brain temperature, it seems that the owners of this hypothesis view of the brain as an engine of the car completely, do you notice the amount of yawns being done and you're wearing a hat, with high degree of head or heat when they are infected with fever? You do not yawn at all! On the issue of yawn contagion it is likely some of it is because of the herd instinct or group innate in humans, but the theory remains uncertain as well, and thus no to the moment uncertain interpretation of any of the questions surrounding the mysterious Baltthaab.
Placebo effect
The intended effect of placebo or Placebo improvement is someone who is sick or suffering from something after taking the medicine has no effect on what is suffering from it. In fact most of the new drug trials include two groups of patients are given a real set doses of the drug that is being tested and the group be given another drug has no effect at all, and are randomly this. It may seem clear how this effect is happening to you, if someone told you what he feels nauseous she would give him a grain of sugar or a cup of herbs and assure him that he will help him improve as happened with you is dependent person for anxiety and concern Bmdh Vtahedo stomach, or as happens in drugs nationality improve sexual ability by making the abused abuse is believed to be nothing more than the ability of nationality but in reality they do not do, but in fact the placebo effect is a complex issue more.
Drugs phantom extends the impact of the face blisters to heart disease and asthma, but some doctors have gone and conducted a fake surgery of the knee and the results were on the patient completely Kalhakiqih. Nevertheless, there is disagreement among scientists whether the placebo effect real or not, some of them attributed the healing and recovery operations that occurred after taking the placebo to the body's natural ability to recover, just as happens when you recover automatically without going to see a doctor. In what is this confusing matter, there are studies confirm that the placebo is equal in influence with the real medicine by 50 to 60 percent of cases, there are still theories and other hypotheses are trying to explain this phenomenon, but mostly based on conjecture and weighting without inference, add to it The fact that this phenomenon eventually become stronger and more frequent in recent years and you'll get a new puzzle you can add it to the list of puzzles that science can not yet resolved.

Dreams
Dreams is common to almost all human beings (there are some human beings do not dream at all) and many of us are obsessed with the interpretation and translation of these dreams, but we actually do not concern ourselves with what is most important, why do we dream? In fact if you start the search now why we should learn that we do not know much about the cause of the dreams and their purpose. The famous old Sigmund Freud's theory assumed that dreams is an expression of our desires unconscious, but most scientists do not believe in the validity of this theory today, others believe that the dreams and the means used by the brain to form new ideas through "mutations random thoughts," other theory believes that the dreams and the way the brain to clean itself and get rid of useless thoughts. Of course you are just like me do not agree with these theories, as well as most scientists.
If we add that also animals dream will become more Tqaida it and it will become clear that most of the previous theories though true in the case of human beings can not be true in the case of animals, grotesquely, that dreams are affected by external factors rather than inside our heads, sounds and smells around you while you sleep may affect significantly in the dream that Iraodk content, I think that you should now ask the interpreter of dreams if they had taken into account the magnetic ground before the interpretation of your dream or not.
