They sought to determine if dispositional mindfulness, an individual’s innate or natural level of mindfulness, was associated with lower pain sensitivity, and to identify what brain mechanisms were involved.
“Mindfulness is related to being aware of the present moment without too much emotional reaction or judgment,” said Fadel Zeidan, assistant professor at Wake Forest Baptist Medical Center.
“We now know that some people are more mindful than others, and those people seemingly feel less pain,” said Zeidan, lead author of the study published in the journal Pain.
In the study, 76 healthy volunteers who had never meditated first completed the Freiburg Mindfulness Inventory, a clinical measurement of mindfulness, to determine their baseline levels.
While undergoing functional magnetic resonance imaging, they were administered painful heat stimulation.
Whole brain analyses revealed that higher dispositional mindfulness during painful heat was associated with greater deactivation of a brain region called the posterior cingulate cortex, a central neural node of the default mode network.
Further, in those that reported higher pain, there was greater activation of this critically important brain region.
