We investigated brain functional connectivity comparing no-task resting to breath counting (a meditation exercise but given as task without referring to meditation). Functional connectivity computed as EEG coherence between head-surface data suffers from localization ambiguity, reference dependence, and overestimation due to volume conduction. Lagged coherence between intracortical model...
IntroductionDifferent meditation practices reportedly affect brain electric activity.ObjectivesTo assess common characteristics in brain electric activity during the state of meditation across different meditation traditions.AimsDo meditation traditions share commonalities in EEG spectral power changes from task-free resting to meditation?MethodsData from 71 experienced meditators of five...
IntroductionThe measure of complex dimensionality assesses the number of independent processes that generate an observed time series.ObjectivesTo investigate whether meditation exercises are associated with fewer or more independently active brain processes, and whether different meditation traditions show different results.AimsDoes brain electric complex dimensionality differ between the state...
