The origin of fear is in a corner of the DNA

start the fear from brain This is one of the great challenges facing neuroscientists. Phobias or post-traumatic stress disorder They can deal a serious blow to the normal development of the life of those who suffer from them. Therefore, finding the neural mechanisms they are associated with is vital. Now, a team of scientists from various Chinese and Australian research centers have found a possible key in the mouse genetic material.

These are sequences of what is called unwanted DNA. In other words, genetic material that does not translate into protein. But just because you don’t experience this translation doesn’t mean it’s useless. In fact, in this case, it seems that it behaves like a kind of bridge, which allows the expression of other genes associated with the extinction of fear.

It is important to emphasize again that the study was carried out in mice. This means that we don’t yet know if it could be extrapolated to humans. However, these scientists, whose work was recently published in Cell reports, remember that many fundamental molecules involved in this type of process are conserved in all species, so it is not something that can be ruled out. We should study more, but at least they already have a thread to pull in the face of development future of treatments against post-traumatic stress syndrome or phobias. Let’s see what this thread is all about.

Post-traumatic stress: when fear settles in your brain

the post-traumatic stress occurs when a painful memory it remains fixed in the hippocampus of the brain and it is practically impossible to erase it.

The person who suffers from it continually relives all the pain it has caused him, to the point that on many occasions his life becomes a nightmare. the phobias they are not so much related to mind, but they are also related to fear. Specifically with an irrational fear of something that is generally harmless. Although both can be treated with psychological therapy or even some virtual reality programs, if the situation is serious, especially when it is related to post-traumatic stress, it is much more complicated.
