Study Notes
Mindfulness Practice and Brain Changes
- Mindfulness-Based Stress Reduction (MBSR) training shows positive effects on psychological well-being, extending beyond formal practice time.
- Little is known about the neural mechanisms behind these interventions.
- This study investigates pre- and post-MBSR program brain changes in healthy participants using voxel-based morphometry (VBM).
Participants
- Sixteen healthy, meditation-naïve participants completed an eight-week MBSR program.
- Seventeen participants served as a waitlist control group.
- Participants were right-handed adults aged 25-55.
Intervention
- The eight-week MBSR program included weekly group meetings and home practice, including guided mindfulness exercises (body scan, yoga, sitting meditation).
- Home practice varied across participants in length of time spent.
Data Collection and Analysis
- Participants underwent MRI scans before and after the program.
- Control participants were scanned approximately two months apart
- VBM measured gray matter concentration across the brain, specifically focusing on the hippocampus and insula.
- Whole-brain exploratory analyses compared MBSR participants to controls.
Results - Gray Matter Changes
- Region of Interest (ROI) analysis: Increased gray matter concentration in the left hippocampus in participants who took part in the MBSR program.
- Whole-brain analysis: Significant increases in gray matter concentration were found in the posterior cingulate cortex, the temporo-parietal junction, and cerebellum in the MBSR group compared to the control group.
- No significant decreases in gray matter were observed.
Results - Mindfulness Improvements
- Significant improvements in mindfulness (acting with awareness, observing, and non-judgment) were detected in the MBSR group but not in the control group.
- Amount of mindfulness practice (body scan, yoga, and/or sitting meditation) and improvements in mindfulness scores were not correlated.
Discussion
- Increased gray matter in the left hippocampus suggests possible implications for learning, memory, and emotional regulation.
- Changes in other brain regions (PCC, TPJ, cerebellum) might indicate functional improvements in emotion regulation and self-referential processing.
- Mechanisms underpinning the observed changes are discussed including the possible links to interoceptive awareness, compassion, and embodied self.
- The study demonstrates that mindfulness practice can lead to demonstrable structural changes in response to a short-term intervention. Future studies with larger samples and a control/comparison group would be needed to explore changes in a variety of neural mechanisms in greater detail.
