Sensitivity to pain may depend on your brain structure

People have different levels of sensitivity to pain because of the way their brains are structured, concludes a study published in the journal Pain.

Researchers at the Wake Forest Baptist Medical Center looked at 116 healthy volunteers and tested their pain sensitivity by asking them to rate their pain when a small area on their arms or legs was heated to 120 degrees F. Then the patients underwent an MRI scan to get images of their brain structures.

The results showed that the people who rated their pain intensity the highest had less grey matter in regions of the brain associated with internal thoughts and attention control.

The researchers suggested that people who are good at keeping their attention focused may also be better at keeping their pain under control.
