A neural basis for benefits of meditation
Date:2/13/2013

out" of other sensory or cognitive information in the cortex.

It's a bit like focusing a telescope by precisely aligning the position of two different lenses. The authors' framework hypothesizes that experienced meditators gain the ability to turn that proverbial focus knob to align those different rhythms.

Working with the framework

In the new paper the authors propose that training chronic pain patients in the standardized mindfulness techniques of focusing on and then focusing away from pain, should result in MEG-measurable, testable improvements in alpha rhythm control.

"By this process of repeatedly engaging and disengaging alpha dynamics across the body map, according to our alpha theory, subjects are re-learning the process of directly modulating localized alpha rhythms," they wrote. "We hypothesize that chronic pain patients trained in mindfulness will show increased ability to modulate alpha in an anticipatory tactile attention paradigm similar to that used in [the 2011 study]."

Many such experiments are yet to be done, Kerr acknowledges, and her group can only do so many.

"There are a number of hypotheses in this framework that can be tested," Kerr said. "That's one of the reasons we wanted to put this out as a framework. It is beyond our ability to test all of these ideas. We wanted to make this available to the scientific field and present this unified view."
