To investigate regional differences in grey matter volume associated with the practice of Sahaja Yoga Meditation.
Twenty three experienced practitioners of Sahaja Yoga Meditation and twenty three non-meditators matched on age, gender and education level, were scanned using structural Magnetic Resonance Imaging and their grey matter volume were compared using Voxel-Based Morphometry.
Grey matter volume was larger in meditators relative to non-meditators across the whole brain. In addition, grey matter volume was larger in several predominantly right hemispheric regions: in insula, ventromedial orbitofrontal cortex, inferior temporal and parietal cortices as well as in left ventrolateral prefrontal cortex and left insula. No areas with larger grey matter volume were found in non-meditators relative to meditators.
The study shows that long-term practice of Sahaja Yoga Meditation is associated with larger grey matter volume overall, and with regional enlargement in several right hemispheric cortical and subcortical brain regions that are associated with sustained attention, self-control, compassion and interoceptive perception. The increased grey matter volume in these attention and self-control mediating regions suggests use-dependent enlargement with regular practice of this meditation.
研究与霎哈嘉瑜伽冥想练习相关的灰质体积的区域差异。
对23名经验丰富的霎哈嘉瑜伽冥想练习者和23名在年龄、性别和教育水平上相匹配的非冥想者进行结构磁共振成像扫描，并使用基于体素的形态学测量方法比较他们的灰质体积。
冥想者全脑的灰质体积相对于非冥想者更大。此外，几个主要位于右半球的区域灰质体积更大：岛叶、腹内侧眶额皮质、颞下皮质和顶叶皮质，以及左腹外侧前额叶皮质和左岛叶。相对于冥想者，非冥想者未发现灰质体积更大的区域。
该研究表明，长期进行霎哈嘉瑜伽冥想与整体灰质体积增大有关，并且与几个右半球皮质和皮质下脑区的区域扩大有关，这些区域与持续注意力、自我控制、同情心和内感受性感知有关。这些注意力和自我控制调节区域灰质体积的增加表明，经常练习这种冥想会导致依赖使用的扩大。
