United States, Oct 17 (Canadian-Media): A new study published in Cell Reports on Tuesday said that just like the mechanism to how a home thermostat controls room temperature, human brains also have the power to amplifying or suppressing the pain signals, ScienceXNewsletter reports said.
A new study honed in on the brain circuitry responsible for upgrading or downgrading pain signals, likening the mechanism to how a home thermostat controls room temperature
This was confirmed by Yarimar Carrasquillo, the paper's senior author and a scientist for the National Center for Complementary and Integrative Health (NCCIH), told AFP the region responsible was the central amygdala, which according to her work appeared to play a dual role.
By better understanding the brain mechanisms responsible for pain modulation, researchers hope to eventually find better cures. For example whereas stress or anxiety can amplify pain, being focussed on a task that diverts your attention can reduce pain.
"The healthy response is you get pain, it tells you something is wrong, it heals, and the pain goes away," said Carrasquillo.
"In chronic pain, that doesn't happen, the system gets stuck. If we can identify what makes the system gets stuck, then we can reverse it."
