Dispositional mindfulness and self-referential neural activity during the resting state.

Mindfulness-based interventions have been shown to impact a broad range of outcomes including enhanced attention, memory, and self-regulation. Previously, mindfulness training has been negatively correlated with brain activity across the default mode network nodes following mindfulness-based practice. Currently, little research has been done to understand the neural basis of differences in mindfulness levels in untrained individuals. In this study, we explored the relationship between the amplitude of low-frequency fluctuation (ALFF) and fractional ALFF (fALFF) during the resting state and the level of dispositional mindfulness, which was measured by using the Five Facet Mindfulness Questionnaire (FFMQ). The results showed that the total scores on the FFMQ were negatively correlated with the spontaneous activation of left premotor cortex. This indicates that individuals with higher levels of dispositional mindfulness might require less effort to control their irrelevant motor responses.
