“We were able to show that the training improved the connection between a central nervous system structure, the anterior cingulate, and the parasympathetic part of the autonomic nervous system to help put a person into a more bodily state,” Posner said. “The results seem to show integration — a connectivity of brain and body.”

How do these changes speak to state vs. trait-level changes in self-regulation? 5 Days of training is a short period of time to show such changes, but they are likely to disappear within the same amount of time. Continued practice is clearly essential for sustained trait-level changes.
