group of American scientists from the University of California at Los Angeles (University of California, Los Angeles) have discovered a gene that carries the responsibility for the human perception of physical pain, as well as social exclusion.The study, which is in question here, was conducted with the participation of 122 volunteers with different gene variants «OPRM1».
In the course of their work Californian experts studied variants of the gene responsible for encoding the mu-opioid receptors, which respond to the influence of narcotic painkillers morphine series.
At the first stage of the study all participants were asked to self-assess their response to social exclusion with a specially drawn up questionnaire.Then, in the second stage of the experiment, the authors proposed a test to play a computer game with two opponents, during which opponents started playing with each other, completely ignoring the third party.It was during these gaming sessions scientists studied the work responsible for the
reports on the pages an Internet resource medportal.ru, an analysis of the information received showed that the strongest response to social exclusion showed participants who possessed a rare gene variant «OPRM1», and the carriage of this variant also presents a sensitivity topain.The authors also emphasize that in these subjects was recorded increased activity of the relevant sections of the cerebral cortex.
In connection with the data obtained one of the study's authors - Naomi Eisenberger (Naomi Eisenberger) - recalled that the number of work previously carried out in this field have revealed the role of the mu-opioid receptors in the human experiences related to his social contacts.As for the recent work of scientists in California, it demonstrates the relationship of the gene encoding the receptors, with the perception of a man of his social exclusion.
In conclusion remains to add that the work of American scientists were published on the pages of authoritative edition «Proceedings of the National Academy of Sciences».
