Previous researchers have studied meditation practices as a means to understand consciousness as well as altered states of consciousness. Various meditation techniques, such as Transcendental Meditation (TM) and Qigong, have been explored with source localization tools; however, the concentrative meditation technique has yet to be fully studied in this manner. The current study demonstrates findings, which outline differential activation in a self-referential default network during meditation in participants who espouse themselves as regular concentrative meditation practitioners, as well as comparisons with a control group practicing a modified version of the relaxation response. The results are compared with other putative experimental findings employing other meditation techniques, and the findings outlined in the current study are discussed with respect to changes in perceptual awareness often reported by meditators.
先前的研究人员将冥想练习作为一种理解意识以及意识改变状态的手段进行了研究。已经使用源定位工具探索了各种冥想技巧，如超觉静坐（TM）和气功；然而，专注冥想技巧尚未以这种方式得到充分研究。当前的研究展示了一些发现，这些发现概述了自称定期进行专注冥想练习的参与者在冥想过程中自我参照默认网络中的差异激活情况，以及与练习放松反应修改版的对照组的比较。将这些结果与采用其他冥想技巧的其他假定实验结果进行了比较，并就冥想者经常报告的感知意识变化对当前研究中概述的发现进行了讨论。
