“…Open We observed significant results solely in the delta frequency band, whereas past meditation research from early on mainly reported findings in the theta, alpha, beta and gamma frequency bands (i.e. Das and Gastaut 1957, Banquet 1973, Hebert and Lehmann 1977, Lutz et al 2004; for an overview see Cahn and Polich 2006). The observed neural plasticity that assumedly carries meditation effects into resting was addressed by several authors (Aftanas and Golosheykin 2005, Lutz et al 2004, Tebecis 1975) who studied Yoga, Buddhist and Transcendental Meditation practitioners.…”

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 neuroplasticity effects of meditation (correlates of increased awareness and detachment) would be detectable in a no-task resting state. EEG recorded during resting was compared between Qigong meditators and controls. Using LORETA (low resolution electromagnetic tomography) to compute the intracerebral source locations, differences in brain activations between groups were found in the inhibitory delta EEG frequency band. In the meditators, appraisal systems were inhibited, while brain areas involved in the detection and integration of internal and external sensory information showed increased activation. This suggests that neuroplasticity effects of long-term meditation practice, subjectively described as increased awareness and greater detachment, are carried over into non-meditating states.Tei, S., Faber, P.L., Lehmann, D., Tsujiuchi, T., Kumano, H., Pascual-Marqui, R.D., Gianotti, L.R.R. and Kochi, K.

“…When the stimulus was presented during a train of theta, the theta was blocked, not being replaced by alpha -the usual arousal reaction in drowsiness -but returning within a few seconds. Banquet (1973) has also reported this phenomenon in TM subjects. Wallace (1970) and Wallace et al (1971) reported no habituation of the blocking response in meditating subjects.…”

“…Wallace (1970) and Wallace et al (1971) reported no habituation of the blocking response in meditating subjects. Banquet (1973), however, reports that with TM subjects there was 'usually no blocking', though click stimulation of theta did produce a blocking effect as reported above. In deep meditation, Banquet found that there was no change in the electrical pattern as a result of stimulation.…”

“…In a further study (Wallace et al 1971), these findings were replicated more generally -the theta trains occurring in the records of 5 subjects. Banquet (1972Banquet ( ,1973, in detailed examinations of the EEG changes in TM, observed a slowing of alpha frequency, an increase in alpha amplitude and the occurrence of the rhythmic theta trains. During 'transcendence ' (the deep stage of TM, presumably the same as the samadhi or ecstasy stage), which was signalled by the subject pressing a push button, patterns of generalized fast activity with a dominant beta rhythm around 20 cps were apparent.…”

“…In a more sophisticated examination of EEG changes, Levine and colleagues (Levine, 1976;Levine et al 1977) investigated the tendency towards EEG coherence during meditation (previously reported by Banquet, 1973), by determining coherence bilaterally and homolaterally between central and frontal derivations of the EEG in a group of experienced meditators. They found evidence of long range spatial ordering during meditation which was not apparent in an eyes-closed relaxation period.…”

SYNOPSIS Previous research on meditation and the EEG is described, and findings relating to EEG patterns during meditation are discussed. Comparisons of meditation with other altered states are reviewed and it is concluded that, on the basis of existing EEG evidence, there is some reason for differentiating between meditation and drowsing. Research on alpha-blocking and habituation of the blocking response during meditation is reviewed, and the effects of meditation on EEG patterns outside of meditation are described. In conclusion, the need for more precisely formulated research is pointed out.
