Brain Plasticity and Neurophysiological Correlates of Meditation in Long-Term Meditators: A 18Fluorodeoxyglucose Positron Emission Tomography Study Based on an Innovative Methodology

Journal of Alternative and Complementary Medicine December 1, 2019 Dipti Magan, R. Yadav, C. Bal et al.

Long-term meditation activates specific regions of the right hemisphere, including the right homolog of Broca's area and the right lentiform nucleus, as measured by changes in regional cerebral glucose metabolism. Using a novel approach with 18FDG PET/CT scans, 12 healthy, male, right-handed long-term meditators (practicing Preksha meditation for over 5 years) showed significantly activated fronto-parieto-temporal regions in the right versus left hemisphere during meditation. These findings suggest that long-term meditation may enhance explicit functions of the right hemisphere through neuroplastic changes.

Mindfulness Meditation Reduces Intraocular Pressure, Lowers Stress Biomarkers and Modulates Gene Expression in Glaucoma: A Randomized Controlled Trial

Journal of glaucoma September 25, 2018 T. Dada, D. Mittal, Kuldeep Mohanty et al.

In a randomized trial of 90 primary open-angle glaucoma patients, 21 days of daily mindfulness meditation lowered intraocular pressure (from about 19 to 13 mm Hg) and improved quality of life compared with a waitlist control. The meditation group also showed reduced stress biomarkers, including cortisol, interleukin-6, tumor necrosis factor-alpha, and reactive oxygen species, and increased beta-endorphins, brain-derived neurotrophic factor, and total antioxidant capacity. Gene expression changes correlated with these biomarker shifts. The authors conclude that mindfulness meditation can be recommended as an adjunctive therapy for glaucoma.
