Genetic fear of spider syndrome

New research by American scientists shows, fear of spiders can be passed down through generations .

The syndrome of arachnophobia is one of the fears - obsessive about extremely popular animals in the world. Accordingly, people with this syndrome are always frightened when they see spiders and feel that a baby is around.

According to a recent study by scientists at Emory University, Atlanta (USA), these symptoms of excessive anxiety, panic and loss of control have appeared since your parents and grandparents. In other words, arachnophobia can be passed down for generations.

In this study, scientists have caused a rat to fear the smell of cherry blossoms and monitor reactions in their next generation. Experts found that the next generation of the mouse was still frightened by the smell of cherry blossoms even when they were conceived by artificial insemination.

Dr. Brian Dias and Dr. Kerry Ressler from Emory University, Atlanta said: "These fears continue to exist even when they are fertilized in vitro. Sometimes, it is inherited up to 2 generations. according to the".

The results of this study provide further evidence of a process called a biological chart . Accordingly, this inheritance affects the structure and nerve function in the next generation. This will help scientists have more research facilities on the transmission between generations that grandparents, parents with neurological disorders, fear, anxiety after trauma .

Professor Marcus Pembrey of the University of London said: "These findings point to a mechanism by which obsession has been passed down for generations. It will help us to have new treatments for problems. mental health ".

The study is published in Nature Neuroscience.
