What is MRI
magnetic resonance image
Types of MRI
Structural
Shows the detailed picture of the shape of the brain
Functional
Shows the activity level in different areas of the brain
Background
Cross sectional research findings
Induviduals meditate vs did not meditate have differences in grey matter in various brain areas
Aim
Identify changes in specific brain regions and the whole brain
By comparing grey matter concentration before and after mindfulness course
Sample
Enrolled in MBSR (mindfulness based stress reduction) course at university of massachusetts to help with stress reduction either because they had chose to attend or had been referred by the doctor
Sample (experimental group)
- Physically and psychologically healthy
- limited experience with the program
- mean age : 38 years old
- race : 13 caucasian, 1 asian, 1 african american, 1 multi-ethnic
sample (control group)
- physically and psychologically healthy
- the same ability eligibility criteria for admission to the mindfulness course, hence they are described as a ‘wait-list’ control group
- mean age : 39 years old
- race : 13 caucasian, 2 asians, 2 african americans, 1 hispanic
procedure
- completed FFMQ (five facet mindfulness questionnaire)
- get MRI scans on 2 occasions:
exp grp : 2 weeks before and aft the 8 week MBSR intervention
cntrl grp : gap of approx 66 days between 2 scans - MRI scans 2 ways
regions of interests : hippocampus n bilateral insulae
whole brain analysis : explore other regions potentially affected by the mindfulness intervention - reported the time they spent on formal homework exercises over the 8 weeks
results
MBSR group participants significantly increased their mindfulness scores on three sub-scales of FFMQ (acting with awareness, observing, and non judging)
when compared to the control group, the changes were significantly greater
left hippocampus : no differnces
region of interest : there is difference for MBSR
Whole brain analysis : mbsr group showed significant increase in grey matter concentration
