Meditation is a complex mental process-practiced widely for stress management and promotion of health- exerts beneficial effects on physical and mental health, and cognitive performance. However, until now, few theoretical neural mechanisms of meditation had been proposed, still not completely elucidated. We have previously evaluated the brain activity during Preksha meditation using an innovative 18FDG-PET methodological approach. Based on our previous study observations, we proposed here the neurophysiological framework of long-term and regular practice of preksha meditation. This mechanism will provide the scientific evidence to understand the attention control mechanisms resulting from the advanced state of preksha meditation. This might have multiple clinical applications as well as effective in a healthy population for attention-related tasks. Also, it is expected that the present neural model will provide a scientific platform for future clinical studies of meditation.
冥想是一个复杂的心理过程——广泛应用于压力管理和促进健康——对身心健康和认知表现产生有益影响。然而，到目前为止，关于冥想的理论神经机制提出得很少，仍未完全阐明。我们之前使用创新的18FDG-PET方法评估了普瑞克斯冥想期间的大脑活动。基于我们之前的研究观察，我们在此提出了长期定期进行普瑞克斯冥想的神经生理框架。这一机制将为理解普瑞克斯冥想高级状态所产生的注意力控制机制提供科学证据。这可能有多种临床应用，并且对健康人群执行与注意力相关任务也有效。此外，预计当前的神经模型将为未来冥想的临床研究提供一个科学平台。
