The scientists taught the rats dit. The rodents put it according to it

In the laboratory of a neurologist at the University of Richmond, a group of laboratory rats learned to drive a small car. The invitation, which had a varied childhood with many stimuli, learned it faster and better.

In Kelly Lambert’s neuroloca lab, getting laboratory calls really didn’t get used to wheels. The team from the University of Richmond in the USA is mainly engaged in research into the influence of the environment on the brain and its function. This means how external conditions affect, for example, decision-making or parent breeding. Or how the upbringing of a rat affects their idisk abilities.

This is really darkness after the last work of darkness (the results are still available on the Behavioral Brain Research website). The scientists built a small rat car for him.

The cars have a cabin made of old plastic feeding bottles with a shaded front view and easy operation. There is a copper plate on the floor, in front of it there are three crumbs, which in fact means left, forward and right. When the figure is invited with the hind limbs on the plate and the front paw touches one of the conductors, connect the circuit and the expression.


A cart built on the platform of an electric rat model at the University of Richmond.

In the study, seventeen guests learned to control the vehicle in such a way that they could drive, and a distance of about one and a half meters. For the sake of completeness, let’s add that the car wheels took place about a week a week for at least fifteen minutes. And instead of a reward in the form of a long paper document of adulthood, the invited at the end of each ride could take sweetness. You can find another example in the article in the magazine NewScientist.

The results of the men showed that the invite, who lived in a rich environment with so many stimuli, learned faster, did better as a result, and forgot the knowledge more slowly forgot. This was the answer of the original author of the study, and it would probably estimate even the most laymen. After all, throughout the study, it turned out that the effect of education on education is relatively easy to prove.

The authors of the study wanted to look at something else: that rats can do difficult trials (even those of a vdc). I think rats are caught, not most people think, Kelly Lambert told New Scientist.

He believes that researchers should not be able to make full use of their ability. Nronj experiments as a result give a better picture of the properties of the brain. The argument is simplified that invites who spend their lives in a cage with a minimum of stimuli will not be a suitable model for studying diseases that also afflict people. Lambert is a neurologist, so he mentions Parkinson’s disease and gave him a neurodegenerative disease, which will be an urgent problem for the tough world.

In the experiment, his car not only observed the differences between the animals with different education, but thus the influence of the well-being of the animals. More specifically, noticeable fluids involve the levels of two hormones associated with stress (corticosterone and dehydroepiandrosterone).

As it turned out, uen (especially spn uen) decreased the level of stress hormone (corticosterone) and increased the level of anti-stress (ie dehydroepiandrosterone). We will mention the terms in quotation marks, because the hormonal system is very complex, you do not usually find it in the middle, these hormones have a number of other functions (just as serotonin is definitely not a test hormone, it is an inappropriate abbreviation). In this case, too, let us find the situation simplified, but not fundamentally distorted.

In any case, it was the case that the woman changed the hormonal balance in the body of the rat, in a substantially positive direction. It was not the very benefit of the ride, but directly, as the control experiment showed. The invitation, which the scientists just carried and did not give them the opportunity to give, responded precisely: there was more hormonal traces of stress in their fluids.

That in itself is not a revolution. Let us recall this as an illustration of the usefulness of students in general. The invites (and all the people and the people) gain not only skills, but also a mental balance. They contribute to this, if they have the possibility of independent decision-making and union. This independence does not have to be absolute, it can even be very doubtful in many respects (rats were, after all, part of a human-prepared experiment), but even in this limitation it is a measurable benefit for mental health.
