Mindfulness Meditation Is Related to Long-Lasting Changes in Hippocampal Functional Topology during Resting State: A Magnetoencephalography Study

Abstract: It has been suggested that the practice of meditation is associated to neuroplasticity phenomena, reducing age-related brain degeneration and improving cognitive functions. Neuroimaging studies have shown that the brain connectivity changes in meditators. In the present work, we aim to describe the possible long-term effects of meditation on the brain networks. To this aim, we used magnetoencephalography to study functional resting-state brain networks in Vipassana meditators. We observed topological modificat… Show more

“…Magnetoencephalographic data were acquired in a 163-magnetometers MEG system 55 , with 9 reference sensors, located in a magnetically shielded room (AtB Biomag UG, Ulm, Germany). The position of four position coils and four reference points (nasion, right and left pre-auricular and apex) were digitized before acquisition, using Fastrak (Polhemus).…”

“…The MEG data were filtered in the band 0.5-48 Hz using a 4th-order Butterworth IIR band-pass filter, implemented offline using Matlab scripts within the Fieldtrip toolbox (44). As described previously (45), Principal Component Analysis was applied to reference SQUID signals to remove the environment noise. Subsequently, noisy channels and bad segments of acquisition were identified and removed through visual inspection by an experienced rater.…”

“…To this end, we applied a dynamic analysis framework to delineate the spatiotemporal characteristics of dynamic FC, which estimates the temporal efficiency of information flow within the brain. Given that brain FC is impaired in MCI and that mindfulness is associated with positive structural and functional connectivity changes in healthy volunteers, we hypothesize that mindfulness practice would improve dynamic FC in subjects with MCI.…”
