Biological Memory: Fears Can Be Passed Down to Future Generations

biological memory fearFear can be transferred from parents to children and grandchildren, claim U.S. researchers in their article published in the journal Nature Neuroscience.

A scientific group of the Department of Psychiatry, Emory University in Atlanta, led by Dr. Brian Dias, conducted experiments on mice and found that a traumatic event can leave an imprint in the DNA of sperm, which in turn can transfer phobia and thus affect the brain structure and behavior of future generations even if they have not experienced the same painful event.

Eye Movement Can Reveal Much about Your Personality and Behavior

eyes behavior personalityEveryone knows the saying that the eyes are the mirror of the soul. Now it seems that their relationship with the brain function is proved. The slightest eye movement can reveal information about the personality and behavior of a person, claims a new study.

Researchers from the Johns Hopkins University found that rapid eye movements show impatience and inability of self-restraint.

Understanding how the brain perceives the time can explain why the decision-making process is more difficult for people with neurological disorders such as schizophrenia or for people who have suffered a head injury. Continue reading

Sleep Disorders: Is It Possible to Die from Lack of Sleep?

insomniaOddly enough neither the reasons nor the evolutionary origins of sleep are known to science. From the standpoint of nature, sleep is hardly something worthwhile. If a person or animal is sleeping, his mind is ‘turned off’ for several hours. Needless to say, that in this state the chance of being eaten by predators grows significantly.

And yet, some regularities, if not reasons, of sleep were discovered by scientists. It turned out, for example, that adults who sleep 6 to 8 hours are characterized by Continue reading

7 Most Controversial Medical Theories Proven True

medical theoriesVery often different theories and studies cause strife in scientific circles, but sometimes even the most unbelievable of them ultimately prove true. See these 7 most controversial theories that were eventually proven true:

1. Air pollution causes lung cancer

Since 1939, many scientists have argued that cancer is mainly caused by various factors such as air pollution. It took 21 years to confirm this theory.

2. Bacteria cause ulcers

In 1982, doctors Robin Warren and Barry Marshall from Australia associated the bacteria «Helicobacter pylori» with the ulcer, but the medical community argued that the cause of the condition was stress in combination with specific food choices. However, in mid 1990s, the American Institute of Health confirmed their theory.

3. The aspirin reduces the risk of heart attack

In 1950, Lawrence Craven from California published his first research which showed that the effect of aspirin prevents the blood clots that cause heart disease. About 40 years later, the prescription of one aspirin a day to patients with heart disease was adopted. Continue reading

«Hello, I am the Lord»: An Unusual Psychiatric Experiment

three jesusesThere was a remarkable meeting in one of the clinics in the U.S. in the mid-1940s. Two patients were having a cute chat, until one of them decided to introduce herself: “Mary, Mother of the Lord.” “But, my dear, this is impossible,” answered the other patient. ”You’re just crazy. After all, I am the Virgin Mary.” The debate dragged on for a long time, and the hospital staff watched them with interest until the eldest of the patients suddenly said: “Well, if you are Mary, then I must be Anna, your mother.” This decision satisfied everybody, and moreover, the elderly patient who demonstrated flexibility soon showed a better response to treatment and Continue reading

5 Common Habits That Are Bad for Our Mental Health

mental health habitsWhen talking about bad habits, usually something like smoking, sedentary lifestyle and poor diet comes to one’s mind. However, the most unhealthy habits are not related to our behavior, but to our psychological state.

To be able to change these habits first it is necessary to know the impact they have on our daily lives.

Loneliness is devastating for both mental and physical health. It makes us feel vulnerable to others, so we become cautious and aloof. Continue reading

Déjà vu: Why Do We Have Memories Coming from Nowhere?

deja vuDeja vu is a very strange and in some cases even unsettling sensation that always causes some confusion. A certain sound, place, or sentence said by someone is perceived as something familiar and makes it feel like if we had previously found ourselves in this situation.

The first visit to a store which made you think that you have already been there once, or the painfully familiar face of a person you see for the first time are all symptoms of deja vu.

The French term déjà vu can be translated as “already seen.” However, even if we are insistently trying to recall exactly when we saw it, it is impossible. Deja vu is linked to several concepts: Continue reading

Possible to Overcome Phobias While Sleeping!

phobias sleepEveryone has fears, either kept private or expressed openly. Some people get trembles and shaky hands at a fear of public speaking, or supervisors, some people are afraid of heights, high speeds or stuffy confined spaces. Phobias are a common thing, but letting them go is not so simple. Soon it may become possible to replace sessions conducted by psychiatrists with an unusual and pleasant treatment … during our sleep, scientists say.

Are you afraid to ride subway, to meet with your own boss or look down from the balcony on the fifth floor? Perhaps, getting rid of these phobias, instead of a chair in the office of a psychiatrist, pillows and blankets will be just as efficient. Targeting brain activity during sleep can help mitigate the effects of fear-inducing memories, researchers claim. Continue reading

Could Déjà Vu Be a Way to Obtain Information from Other Dimensions?

deja vu inter dimentionalDeja vu is one of the little-known and mysterious phenomena of our psyche. Many people sometimes feel that a situation in their life has already been experienced before in all the details. But how and when? This phenomenon is called déjà vu, which in French means ‘already seen’. It is a condition in which a person feels that once he already experienced a situation of the present, but the feeling is not associated with a specific moment of the past, but refers to the past in general.

Deja vu is quite common. Psychologists believe that 97 % of people have experienced it at least once. Sometimes people are afraid of deja vu and worry about their mental health. What lies beyond human understanding, always frightens us.

The reasons that cause the phenomenon are still not clear. It might be caused by the processes in the parts of the brain associated with memory and perception. There is a hypothesis that sometimes the perceived information gets to the memory areas sooner than to the area of the primary analysis. Thus, the brain, comparing the situation with its ‘neurocopy’ already received by the memory, concludes that it already happened before. Continue reading
