Aju õpib valu ohjama

Allikas: www.novaator.ee
Psühholoogidele ja füsioloogidele on pikka aega teada, et ühes kehapiirkonnas olev valu väheneb siis, kui mingi muu kehaosa valutama hakkab. Selle taga on närvisüsteemi kaitsemehhanism, mis aitab inimkehal kohaneda uute ohtudega.

Närvisüsteem aitab inimesel toime tulla ohtudega

Samuti kipub meie aju seostama sageli koos esinevaid sündmusi. Luksemburgi ülikooli neuroteadlased panid need teadmised kokku ning vaigistasid valu helide abil.

Vabatahtlikele katsealustele anti jala pihta nõrk elektrilöök ja lasti inimestel hinnata valu tugevust. Seejärel panid vabatahtlikud käe jääkülma vette. Jalavalu taandus ning samal ajal kõlas nende kõrvaklappides telefonihelin.

Katset korrati mitu korda ja lõpuks hakkas inimestel jalavalu vähenema ainult telefoniheli kuulmisel. Katsealused hindasid oma valu väiksemaks ja see peegeldus ka näiteks nende näoilmetes.

Uurimuse autori Fernand Antoni sõnul oli ajus tekkinud seos, mis pani heli mõjul tööle valu blokeeriva mehhanismi. Uurija kinnitusel sarnaneb see Ivan Pavlovi kuulsale eksperimendile, kus koerad õppisid toitu seostama kellahelinaga.

Ilmselt esineb vähemalt osadel inimestel ka vastupidine nähtus ja mingid tegurid võivad neil valutundlikkust hoopis suurendada.

Uurimus ilmus ajakirjas PLOS ONE.

Dr joy is a trust worthy spell caster and he will be of great help to you. I never believed in spell casting but After 4 years of marriage my husband left me because I lost my womb, and i was unable to give birth to children. I felt like my life has come to an end, and i almost committed suicide, i was emotionally down for a very long time, but thanks to this spell caster called Dr joy whom i met online after my friend Becky Ross told me how he also helped her to bring back her husband in less than 2 days. I believed her and decided to give Dr joy a try and i contacted him on his email joylovespell@gmail.com. and explained my problems to him. He laughed and told me that In less than 2 days, my Husband will come back to me again, and that he will restore my womb and i will give birth to children. At first i thought it was a joke but i took courage and believed as Dr joy has said and it did happen just as this Great spell caster said, My husband called me and was crying, begging for forgiveness. I forgive him and today i am so glad that all worries and problems has gone away, and we are even happier than before, another good news is that i am pregnant now, and very soon we will have our baby.
