To erase the negative memories is something that our mind knows to do. But, how? In the central nervous system we have receivers of cannabinoides, that are the substances that cause that the bad thoughts disappear. This discovery of the scientists would mean that through these substances diseases could be cured, such as the anxiety that causes post-traumatic stress, the phobias and the attacks of panic.
Amalia Garci’a-Mayor, CNN+. It is in the tonsil where these cannabinoides are concentrated that, when suffering fear, go off towards the nervous cells. The medicines that could be created must be centered in harnessing the cannabinoides in this part of the body and extracting them for their treatment.
Reason why it is seen, the own nature helps to make disappear the bad memories. Through the mice this can be appreciated, according to Beat Lutz, of the Institute Max Planck de Psiquiatría de Munich. The discovery can take to fix the mental problems of people. “We could understand the problems of anxiety by means of this system”, comments Lutz.
The chemical assets of the marijuana, tetrahydrocannabinol or THC, are looked like the receivers of canabinoides of the brain that are related to the sensations of pain, the emotions and the movement. In the last decade the investigators have already found created chemical substances in the brain that are similar to the THC.
Fear in the mice
The investigators have experimented genetically with the mice so that they needed a particular type of receiver of cannabinoides called CB1. Normally, since already there are saying, they are in the tonsil, a zone of the brain that is associated to the fear.
Soon they conditioned the mice, next to which they had not undergone alterations, to associate a concrete tone of music with an electrical shock. Both groups of mice learned express the fear association, dying whenever they heard the sound. One week later, the mice exposed themselves repeatedly to tones but without the electrical shock. The normal mice forgot their fear immediately, whereas the mice still modified were fear 11 later.
The investigators saw that the modified mice had suppressed the bad memories, but took six times more than the normal ones. The group of Lutz also demonstrated that blocking the receivers of CB1 in the normal mice he produced he himself effect to them of not forgetting the bad memories that to the other animals
The equipment of Lutz later studied the tonsil of the mice, and confirmed that the animals that were now forgetting the disagreeable association had greater levels of two important cannabinoides - anandamide and 2arachidonolglicerol- that those that never had been trained.
This suggests these chemical substances help to erase the bad memories in relation to receivers CB1.
Lutz also aimed that the marijuana in itself is a potential treatment since activates all the receivers of cannabinoides of the blow brain.
Relation of the canabinoides and the porros
The marijuana has been used of medicinal form during hundreds of years and people with certain psychic conditions, like the schizophrenia have had always more facility to smoke porros that healthy people.
Porro therapeutic not exite like so, but can be spoken of users of medicinal cannabis. The only problem that it has is that the smoke, aside from cannabinoides contains tars and gases several. Nevertheless, it is not necessary to forget the advantages the cannabinoides.
To eat cannabis is another option not to inhale the negative substances, but the metering is complicated and the unpredictable effects. When metabolizar itself in the liver no longer it arrives at the brain the cannabinoide but something different, a modified substance that can get to cause mareos, malaise or anxiety.
