Recently, a group of scientists issued a statement that up to 40 percent of people are infected with brain parasites capable of affect human behavior.
Professor of Epidemiology, London Imperial College John Webster explains this by the fact that parasites in the brain are isolated and protected from attacks by the immune system. According to him, it also gives them the opportunity affect human behavior.
The common unicellular parasite found in domestic cats Toxoplasma is able to infect 350 thousand Britons per year. Professor of Evolutionary Biology, Charles University of Prague Yaroslav Flegr connects the influence of toxoplasma with a tendency to sloppy driving and suicide.
A study by Imperial College scientists concludes that Toxoplasma infected mice did not repel, but, on the contrary, attracted by the smell of cat urine.
Presented in the form of microscopic cysts of toxoplasma was found in two areas of the brain: those responsible for fear and pleasure. The repulsive reaction to the smell of cat urine was lowered, and an increase in the concentration of dopamine hormone, usually produced in rodents in response to the smell of urine of females, was triggered in response to a cat smell. Recent studies also showed that toxoplasma DNA includes two enhancing dopamine gene production. Similarities in the structure of the human brain and rodent brain suggests that most automobile accidents among those infected with toxoplasma could be caused dulling feelings of fear.
Scientists estimate that 40% of the UK population may be infected with toxoplasma. However, despite the fact that their research relate directly to the UK population, the parasite so common around the world, these 40 percent can relate to the population of the whole globe.
In another study led by Dr. Barragan and conducted in collaboration with researchers of Uppsala University, was published in the scientific journal PloS Pathogens. a recent interview with Dr. Barragan stated that the problem Toxoplasma infection is not new to humanity:
We consider this knowledge important for a further understanding of some major health issues that modern science does not can give answers … At the same time, it is important to emphasize that people lived with toxoplasma for millennia, so this is not cause for concern modern parasite carriers.
We did not consider the behavioral changes of those infected. people, as they were mentioned in previous studies. Instead, we discovered the mechanisms of parasite penetration into the brain. and media manipulation.
The main goal of research is to understand the mechanisms messages of brain neurotransmitters among themselves, and its results most likely to be used in the development of psychiatric preparations.
Although to have an idea and understanding of the mechanisms and functions the human body is useful, it is important to monitor the progress of such studies in order to exclude the possibility of their use with intentions to control the population.
Regarding the parasite itself, in most cases it is safe, unless it can make you a little crazy, although we are all in to some extent a little crazy, so it doesn’t have much values.
