Objectives The objective was to analyze EEG recorded during Brahma Kumaris Rajyoga meditation (BKRYM) using eLORETA applied in the frequency domain for localizing sources during meditation vis-à-vis baseline condition. Unlike many other popular meditation practices, BKRYM is practiced with open eyes. To our knowledge, there has been no study of the changes in the brain’s activity during the...

Brahma Kumaris Rajayoga’s open eyed ‘seed stage meditation’ was studied in 52 meditators. Meditation stages: concentration on peace, realization of being a soul and communion with the Supreme Soul. Frequency domain brain electric source localization was used on multichannel EEG recordings to establish activation differences between meditation and open eyed, task-free resting. Additional...

Two phases of Transcendental Meditation (TM)-transcending and undirected mentation-were compared to each other and to task-free resting using multichannel EEG recorded from 20 TM practitioners. An EEG microstate analysis identified four classes of microstates which were labeled A, B, C and D, based on their similarity to previously published classes. For each class of microstates, mean...

Meditation is a self-induced and willfully initiated practice that alters the state of consciousness. The meditation practice of Zazen, like many other meditation practices, aims at disregarding intrusive thoughts while controlling body posture. It is an open monitoring meditation characterized by detached moment-to-moment awareness and reduced conceptual thinking and self-reference. Which...

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...

Many meditation exercises aim at increased awareness of ongoing experiences through sustained attention and at detachment, i.e., non-engaging observation of these ongoing experiences by the intent not to analyze, judge or expect anything. Long-term meditation practice is believed to generalize the ability of increased awareness and greater detachment into everyday life. We hypothesized that...

Multichannel EEG of an advanced meditator was recorded during four different, repeated meditations. Locations of intracerebral source gravity centers as well as Low Resolution Electromagnetic Tomography (LORETA) functional images of the EEG 'gamma' (35-44 Hz) frequency band activity differed significantly between meditations. Thus, during volitionally self-initiated, altered states of...
