The pleasure from process of a cognizance new is stronger some cocaine
Experiments established that pleasure from process of knowledge can exceed euphoria from the use of drugs, writes One-fact.ru.
Scientists from University of Nebraska made experiment with the rats dependent on cocaine. Animals of the first group received low (7,5 mg/kg), averages (20 mg/kg) and high (30 mg/kg) drug doses, and the second – the fixed dose (10 mg/kg), but during different time: 1 day, 2 weeks or 4 weeks. Neurophysiologists tried to interest rats and to observe that will appear stronger – bent for to drug or to knowledge.
Animals let out before two rooms, in one of which they traditionally received cocaine, and in other saw a thing unfamiliar to them: fabric slice, newsprint, etc. Rats could choose, into what of rooms to them to come, that was stronger, bent for to drug or curiosity.
Poorly dependent rats receiving a small dose or average, but it is short, usually preferred the second room of the first. But than more long and than a big dose accepted an animal, more strongly his priorities were declined that towards a room with drugs. If rats accepted 30 mg/kg of cocaine a day or 10 mg/kg, but within 4 weeks, the realized choice already could not do. All their activity was limited to passive expectation of the next dose.
On the basis of experiment scientists drew a conclusion that easy or average degree of a drug addiction are surmountable by means of needs of nature of a brain in new knowledge («a knowledge instinct»), capable to move even physical bent for to psychoactive substances.
The Danish experts carried out other research explaining this phenomenon. The communication proof between desire of the person to learn new and production дофамина was the purpose of experiment.
Dofamin – a neuromediator causing in the person feeling of pleasure, be that tasty food, sex or achievement of a goal. Also дофамин it is allocated and in the course of knowledge. But the volume of its synthesis when receiving new knowledge differs from the person to the person. Scientists assumed that the quantity of a being produced mediator and its primary localization are directly connected with psychotype of its personality.
The volunteers participating in experiment, passed usual psychological tests. Further they were given out the tasks directed on increase in volume of knowledge, at the same time watching concentration дофамина in a brain.
Organism of examinees, according to psychological tests appeared very inquisitive, developed a large number of a mediator which it was distributed evenly on all volume of a brain. Respectively, they received most of all pleasures that pulled them to receiving all of new and new knowledge.
So, scientists proved that bent for to knowledge is absolutely objective phenomenon fixed biochemical. For the people inclined to increased development дофамина, research of various areas of life is a peculiar drug.
Experts consider that totally from these two researches it is possible to draw a conclusion that the people aspiring to knowledge, are less subject to risk to run into drug addiction, and also can easier get out of it.
