Functional magnetic resonance imaging of hippocampal activation during silent mantra meditation.

摘要: Objectives: The objective of the present study was to investigate whether moderately experienced meditators activate hippocampus and prefrontal cortex during silent mantra meditation, as has been observed in earlier studies on subjects with several years practice. Methods: Subjects less than 2 meditation practice according Kundalini yoga or Acem tradition were examined by functional magnetic resonance imaging using an on-off block design. Whole-brain well region-of-interest analyses performed. Results: most significant activation found bilateral hippocampus/parahippocampal formations. Other areas middle cingulate precentral cortex. No anterior found, only small clusters Conclusions: In conclusion, main finding this hippocampi, which also correlated previous very meditators. We propose that is activated already after moderate different modes including relaxation. role hippocampal activity should be further clarified future studies, especially investigating meditation-correlated related memory consolidation.
