Recent research had found
"pain sensors" as a response in the brain when we step on tacks or
when the object hit the elbow bone.
Researchers conducted brain
imaging scans of people who suffer the pains of waxing and subsided for a few
hours. They identified a part of the brain called the dorsal posterior insula,
which becomes active when a person responded to pain experienced.
"We have identified areas of the brain that is
responsible for the core 'sick' of the experience of pain," said lead
investigator and professor of anesthetic science at the University of Oxford,
England, Irene Tracey.
These findings could one day help doctors detect the
illness in people who are not able to communicate well, like a child, one who
is in a coma, or dementia. This research has been published on March 9 in the
journal Nature Neuroscience.
In the study, Tracey and his colleagues greasing creams
contain chemicals capsaicin, an ingredient in chili peppers that causes a
burning sensation, at 17 feet healthy volunteers. Researchers then put a hot
water bottle or cold water on her skin to increase or decrease their pain.
Meanwhile, they scanned the brains of study participants
and asked them how much pain they feel. They found that the dorsal posterior
insula more shine in brain scans when participants reported intense pain,
concluded that this part is a measure of pain in the brain.
