Study Notes
Hölzel et al. conducted a study to explore how mindfulness meditation can lead to structural changes in the brain, specifically increases in grey matter concentration in certain regions. The study used MRI and voxel-based morphometry to measure these changes after an eight-week Mindfulness-Based Stress Reduction (MBSR) programme.
- Mindfulness — a mental state achieved by focusing on the present moment while calmly acknowledging and accepting one's feelings, thoughts, and bodily sensations.
Example: Practicing meditation to reduce stress and improve wellbeing. - Mindfulness-Based Stress Reduction (MBSR) — an eight-week programme teaching meditation practices to cultivate mindfulness.
Example: Participants attend weekly sessions and practice daily meditation. - Localisation of Function — the principle that specific brain areas are responsible for particular cognitive functions and behaviours.
Example: The hippocampus is involved in learning and memory. - Voxel-Based Morphometry (VBM) — a neuroimaging technique that measures grey matter concentration in the brain.
Example: Used to compare brain structure before and after MBSR training.

Common Confusions
- Confusing mindfulness with general relaxation techniques
- Assuming brain changes are solely due to meditation without considering other factors
Typical Exam Questions
- What is mindfulness?
Mindfulness is a mental state achieved by focusing on the present moment while acknowledging and accepting one's feelings and thoughts. - How does MBSR affect the brain?
MBSR can lead to increases in grey matter concentration in specific brain regions. - What is the role of VBM in this study?
VBM measures changes in grey matter concentration using MRI scans.
What Examiners Usually Test
