  Figure 1. Band power of Alpha 1 (8–10 Hz) electroencephalography band measured in anterior frontal, medial frontal, lateral frontal, and parietal regions for resting and during meditation in control and meditators groups, respectively

• 

  Figure 2. Band power of Alpha 2 electroencephalography band (11–13 Hz) measured in anterior frontal, medial frontal, lateral frontal, and parietal electrode clusters for resting and during meditation in control and meditators groups, respectively

• 

  Figure 3. Band power of theta electroencephalography band (3–7 Hz) measured in anterior frontal, medial frontal, lateral frontal, and parietal electrode clusters for resting and during meditation in control and meditators groups, respectively

• 

  Figure 4. Index of alpha asymmetry measured from alpha band power at lateral frontal and medial frontal electrode clusters in premeditation baseline, during meditation for long-term meditator group, and resting in control group

• 

  Figure 5. Index of hemispherical alpha band asymmetry measured at anterior frontal, medial frontal, lateral frontal, central, occipital, parietal and temporal electrode clusters in premeditation baseline, during meditation for long-term meditator group, and resting in control group
