Are brain cells restored? 

A group of researchers at the University of Salgrena in Gothenburg discovered a new section of the human brain. This is a small tube, which is its own "workshop" for restoring brain cells. Discovery is extremely important for understanding how damage is restored in the brain, for example after a stroke, accidents with cranial trauma or Parkinson's, Alzheimer's and multiple sclerosis. True, the path from today's discovery to the manufacture of drugs in this area will take several years. The size of the tube found by Swedish scientists is 1 mm in diameter and 3 cm in length. Previously, doctors believed that it is only in animals. "We generally believed that we knew everything about the human brain," says neuroscience professor Peter Eriksson. "This discovery even puzzled us, since it is not possible to find an entirely new structure every day." Now, doctors have to develop a new type of treatment, which, in fact, means stimulating the cells already in the brain. From experiments conducted on animals, researchers know that such treatment leads to a faster and more effective healing.

Down's disease will be treated

American scientists believe that they managed to find a way to prevent a delay in mental development in Down's disease. In experiments on mice with similar genetic disorders, researchers were able to significantly improve the learning ability of these animals with a drug called pentylenetetrazole. Down Syndrome is a congenital disease caused by a violation of the number of chromosomes: in the 21st pair in such patients there are three, and not two, as in the norm, chromosomes. In their study, the staff of Stanford University proceeded from the hypothesis that a significant part of cognitive (cognitive) disorders in patients with Down's syndrome is associated with an elevated level of gamma-aminobutyric acid, which has a retarding effect on brain nerve cells. Pentylenetetrazole blocks the cellular receptors for gamma-aminobutyric acid. The action of pentylenetetrazole was tested on laboratory mice, which are considered to be the ideal biological model of Down's disease. These animals lag far behind in development from healthy relatives, In particular, they are not able to find a way out of the labyrinth, in which the usual mouse is oriented without much difficulty. After a 17-day course of pentylenetetrazole, the experimental mice began to orientate in the labyrinth suggested by them no worse than healthy rodents. According to scientists, the beneficial effect lasted at least two months after the discontinuation of the drug.
