scientists have confirmed a recent study, the so-called "fear scent" does exist. The researchers explained that the skin secretion of the body of some special chemical substances (pheromones), one can fear his "transmission" to the people around. In addition, this information can also be passed on to many people around.

a total of 49 volunteers took part in the scientists from the University of Dusseldorf, Germany organized a special test. The course of the experiment, Dr. Jin Na Bethe and his colleagues used a small cotton were collected in 21 volunteers an hour before the start of the examination of the secretion of sweat and bike links in the training unit of the sweat secreted.

other 28 volunteers were asked to smell of sweat collected and determine what is collected before the exam, which are collected during training.

although no one volunteers to make the correct distinction, but the brain scanning equipment has shown that when volunteers were collected before the exam smell of sweat, the brain responsible for emotional and social parts of will show the more active. Scientists believe that volunteers reflect the description of the brain, people feel fear and panic when the secretion of special chemical substances will be infected with other people around.

There are many scientists believe that, although the smell in the relationship between people play a very important role, but research on them is extremely limited. Earlier tests have shown that the male immune system strong by emitting temperatures will make it easier to attract women, because the temperature can make the next generation better resistance disease . In addition, when people are looking for a spouse who would be more willing to choose a larger temperature difference with their own people, as it can to avoid as much as possible consanguineous marriage of the situation.

the U.S. Department of Defense funded a study last year also shows that the spirit of fear or tension from the body are stimulated by the scent of fear of other people related to regional brain responses. Used in the trial were collected from the sweat from the first jump. Analysts have pointed out that the U.S. military hoped that such tests can play a key role in extracting the chemical substances in order to force the enemy to create a climate of fear.
