In certain areas of the Brains and more Gray matter – especially in the Hippocampus and the cerebellum forms in the case of young people after Smoking Weed. But Is that also good for Thinking, or rather bad?
More than a third of young people in Western industrial countries have already smoked up a little before your graduation
“Grey cells” in the people’s mouth as something Good: an expression of the thinking ability and intelligence. But not always it needs to be healthy, if the amount of the so-called Gray substance (GS) is increasing in the brain.
This happens namely in the case of growing teenagers, the pot – even if you only do it rarely. A team of researchers from the USA, the UK, Germany and Austria, this is the discovery on the 14. January 2018 in the Journal of Neuroscience published.
The Team of Catherine Orr from the Department of psychiatry and psychology at the American University of Vermont found that already a very low Cannabis consumption causes in adolescents measurable changes in the brain. Until the end of puberty the brain is still in the growth phase and is therefore particularly sensitive to the active ingredient Tetra hydro cannabiol (THC), triggers when you smoke Weed intoxication.
More to Grey cells: What Stress makes with the brain?
Subjects had only once or twice smoke weed
With MRI and voxel-based morphometry volume of cell types can be calculated
The researchers compared the brain scans of 92 teenagers at the age of 14 years. Half of the subjects had already had experience with marijuana or hashish, and the other half.
The scientists used the so-called “voxel based morphometry”. That is to say: they used images from a magnetic resonance imaging (MRI) to measure certain parameters in the brain quantitatively.
It was found that the Gray matter was grown in those who had only smoked pot like once or twice, in volume, in the Hippocampus and in the cerebellum. These areas bring neurologists usually with the Endocannabinoid System. So this is the area of the signal system, the the active ingredients of the Cannabis scheduling.

Grey matter – the centre of our nervous system
As a Gray substance by medical experts to denote in particular the nerve cell body and core areas of the Central nervous system. The White substance is, however, especially from the pathways for the Transmission of the information. The nerve fibers and nerve cell processes.
The color designation of the different areas of the nerve cells is, therefore, that the respective materials discolor gray or white, if they are placed in Formalin. The solution is used for disinfection and preservation of protein-containing biological preparations.

Risk for the brain: stroke, dementia often follows
A little basic research with kiffenden Minors
Whether the increase in Gray matter is now seen as useful or more harmful, the researchers wanted to do not set. In any case, caution in the Interpretation of the data was appropriate. Is Among the Cannabis Users Adolescent to observe Doctors, an increased number of anxiety disorders.
Between 30 and 40 percent of adolescents in industrial countries such as Germany and the United States before the end of the middle school’s first experience with Cannabis.
The doctors assume that this has long-term effects on the nervous system. However, there are few studies on adolescents that consume only sporadically Cannabis. The majority of scientific studies deal with adults who have used over many years, Cannabis intensively.

Squirrel: planning of the nut-hiding increases the size of the brainNimble climbers with a huge leap in power
Squirrels are the kings of the trees. Its striking bushy tail serves as a control and balance rudder, in the case of daredevil jumps from tree to tree. In addition, the exceptional anatomy of the jump, allows joints with a 180-degree rotation of the feet to the back for quick head-down climbing on tree trunks.

Squirrel: planning of the nut-hiding increases the size of the brainA Variety Of Dining Plan
The range of food for small rodents varies depending on the Season: in the spring of fresh buds and young shoots and the seeds, so the Buffet in the summer and autumn is stocked with plenty of delicious fruits, nuts, mushrooms and berries. But also in the cold Season, squirrels have to eat, after all, they do not hibernate.

Squirrel: planning of the nut-hiding increases the size of the brainLaborious to Collect and Hide
Therefore, the rodents must accumulate in the fall of a large stock of food. In the case of the nut-search and storage of a number of things must be considered: Where is the perfect hiding place, that is, in the end, found again? What is the nut corresponds to the quality criteria to be hidden at all? This requires a high level of thinking power of the squirrel during the autumn of collective action.

Squirrel: planning of the nut-hiding increases the size of the brainA lot of nut, much of the brain?
Researchers from the University of California, Berkeley have discovered that some squirrels in the fall to think so much of nuts and their storage, that your brain is in this Season much greater than in the rest of the year.

Squirrel: planning of the nut-hiding increases the size of the brainEach Lot Of Nuts To Hide
Especially in the case of the Grey squirrel, the magnification of the brain: you buried your stock is widely scattered in their area and, thus, have numerous hiding places, you need to remember. Red squirrels bury their Treats rather point the way and defend the thieves of the stock then in front of the possible Lining.

However, not only is the correct storage location is an important criterion for the winter stock, the quality of the nut has to be right: The researchers assume that squirrels check in by using a particular head movement, the weight of a walnut, and with her fine paws, the Freshness and the condition of the shell check. In painstaking precision is to study each individual nut.

When just the smell helps them find meaning: researchers found that the rodents in the foresight of the nut-types sorted from each other and buried it. Thus, can remember the rodents better to hide – and Survive. Because the faster a squirrel finds its stock, the more nimble it can go back in the warm and safe Nest.

Wrestling is not just for Show. One thing is certain: The brains of some wrestlers have been seriously damaged-thanks to repeated head injuries seriously. As the canadian Wrestler Chris Benoit at the age of 40 years, self-shot, found Doctors that his brain resembled that of an 85-year-old Alzheimer’s patient.

Doctors even have a name for this disease: chronic traumatic encephalopathy, or simply Boxer’s syndrome. And it means: a Permanent shock to the head change the brain – for the Worse. The result is memory loss, difficulties, thoughts of suicide, and finally, dementia voice. The disease was first discovered in the case of professional boxers, hence the Name.

The Boxer’s syndrome is not just a Boxer. Especially in the case of American Football players, the disease is often. According to the journal “Science”, suffered by the average National Football League player over the course of a season, over 600 kicks on his head. Even the hard-shelled helmets, are not able to absorb the shocks completely.

The National Football League denied for many years that their players could be affected by the Boxer’s syndrome. In the meantime, she has changed around and a few rules of the game, to head-to-head Collisions to be avoided. At the same time, researchers are working on magnetic inserts for Football helmets. Repulsive forces should weaken a collision before it happens.

It seems strange, but Yes: Even football players are at risk by their headers. The forces which are effective, seem harmless in comparison to the violent collisions in American Football or hockey game. But even small forces can add up with time.
