While growing evidence supports that dispositional mindfulness
relates to psychological health and cognitive enhancement,
to date there have been only a few attempts to
characterize its neural underpinnings. In the present study,
we aimed at exploring the electrophysiological (EEG) signature
of dispositional mindfulness using quantitative and
complexity measures of EEG during resting state and while
performing a learning task. Hundred twenty participants
were assessed with the Five Facet Mindfulness Questionnaire
and underwent 5 min eyes-closed resting state and 5 min at
task EEG recording. We hypothesized that high mindfulness
individuals would show patterns of brain activity related to
(a) lower involvement of the default mode network (DMN)
at rest (reduced frontal gamma power) and (b) a state of ‘task
readiness’ reflected in a more similar pattern from rest to
task (reduced overall q-EEG power at rest but not at task),
as compared to their low mindfulness counterparts. Dispositional
mindfulness was significantly linked to reduced frontal
gamma power at rest and lower overall power during rest
but not at task. In addition, we found a trend towards higher
entropy during task performance in mindful individuals,
which has recently been reported during mindfulness meditation.
Altogether, our results add to those from expert meditators
to show that high (dispositional) mindfulness seems to
have a specific electrophysiological pattern characteristic
of less involvement of the DMN and mind-wandering
processes.
