system of the person, is the most exact, difficult and organized and also most fragile system of an organism. And the brain, in turn, is responsible for behavior of all body organs and also all systems. The nicotine which is contained in cigarettes gets into lungs, then in blood, and later into a brain. He creates a barrier to the main canals of a brain, thereby weakening communication between them. The brain of the person which is under the influence of nicotine simply is not capable to refuse it. Instead the brain is accented on other problems, more solvable. Here to what conclusion scientific America came.
Scientists from the University of Pennsylvania made an experiment as a result of which it became clear that in the USA, smoked about 43% of all population 50 years ago, that is every second inhabitant who reached majority. By the present moment, this indicator decreased to 19%, it of course pleases, however on it decrease stopped.
Smokers, by the way, say that they would like to leave off smoking, but just it is impossible to them. And it is not surprising, the brain which is under nicotine loses all determination. And relentless scientists look for to it the reason.
For this research several volunteers were called by age from 19 to 60 years. Each of them smoked a minimum on a pack of cigarettes in day.
It is important to learn how to leave off smoking, it not only will save to you money but also development of mind will smoke :)
The essence of an experiment consisted in check of activity of a brain during the use of nicotine and after daily abstention from it.
For check the device MRT (magnetic and resonant tomograph) was used.
At the first stage of an experiment, to each volunteer allowed to smoke on a cigarette then placed in the device for check.
At the second stage, volunteers were placed in the device after daily abstention from nicotine.
Results of an experiment these are what, after abstention, communication between canals of a brain was strongly weakened, and on the decision even of the simplest tasks a lot of time left.
And it means that the brain which got used to nicotine is lost without it and is distracted by external factors, struggles with bad mood, and forces on the solution of important tasks it just does not have.
Experiments and researches on it of course are not finished. Scientists only pave the way to physicians who have to find already, at last, that, really effective remedy for fight against so hated habit. Not to mention that such dreadful diseases as cancer, a heart attack, an ulcer, etc. are a consequence of smoking.
