Abstract
VESTERGAARD-POULSEN and COLLEAGUES, Center for Functionally Integrative Neuroscience, Aarhus University, Aarhus, Denmark. peterv@pet.auh.dk report evidence of structural differences in the lower brainstem of participants engaged in the long-term practice of meditation.
Background
Extensive practice involving sustained attention can lead to changes in brain structure.
Methodology
Using magnetic resonance imaging, the authors observed higher grey matter density in lower brain stem regions of experienced meditators compared with age-matched nonmeditators.
Results
Our findings show that long-term practitioners of meditation have structural differences in brainstem regions concerned with cardiorespiratory control.
Conclusion
This could account for some of the cardiorespiratory parasympathetic effects and traits, as well as the cognitive, emotional, and immunoreactive impact reported in several studies of different meditation practices.
