We recorded magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) following noxious laser stimulation in a Yoga Master who claims not to feel pain when meditating. As for background MEG activity, the power of alpha frequency bands peaking at around 10 Hz was much increased during meditation over occipital, parietal and temporal regions, when compared with the non‐meditative state, which might mean the subject was very relaxed, though he did not fall asleep, during… Expand
Meditation reduces pain-related neural activity in the anterior cingulate cortex, insula, secondary somatosensory cortex, and thalamus
TLDR
It is hypothesized that meditation reduces pain-related neural activity in the ACC, insula, secondary somatosensory cortex, and thalamus and suggested that the characteristics of the modulation of this activity may depend on the kind of meditation and/or number of years of experience of meditation.

[Mechanisms of intracerebral pain and itch perception in humans].
TLDR
The findings obtained after itch stimulation were similar to those obtained after pain stimulation, but the precuneus may be an itch-selective brain region, confirmed by both MEG and fMRI studies. Expand
Tonic thermonociceptive stimulation selectively modulates ongoing neural oscillations in the human posterior insula: Evidence from intracerebral EEG
TLDR
It is shown that the human insula exhibits activity preferential for sustained thermonociceptive and vibrotactile stimuli, which could lead to new insights into the physiological mechanisms of nociception and pain perception in humans. Expand
Medial profrontal cortex and anterior cingulate cortex in the generation of alpha activity induced by transcendental meditation: a magnetoencephalographic study.
TLDR
It is suggested that the mPFC and ACC play an important role in brain activity induced by TM, and the dipoles were mapped to both the medial prefrontal cortex (mPFC) and anterior cingulate cortex (ACC). Expand
Meditation experience predicts less negative appraisal of pain: Electrophysiological evidence for the involvement of anticipatory neural responses
&NA; The aim of mindfulness meditation is to develop present‐focused, non‐judgmental, attention. Therefore, experience in meditation should be associated with less anticipation and negative appraisalExpand
fMRI study of pain reaction in the brain under state of "Qigong".
TLDR
The result indicated that the main manifestation of brain functional change under Qigong was functional suppressing, but in some particular regions such as SII-insula region in this study, the response amplitude was increased. Expand
ANALGESIC EFFECTS OF EEG ALPHA-WAVE ENTRAINMENT ON ACUTE AND CHRONIC PAIN
Pharmacological treatments for pain show limited analgesic benefits when compared with placebo. Neuro-modulatory approaches, such as mindfulness meditation and neurofeedback training show moreExpand
Functional neuroanatomy of meditation: A review and meta-analysis of 78 functional neuroimaging investigations
TLDR
A meta-analysis of functional neuroimaging studies of meditation supports the neurophysiological dissociability of meditation practices, but also raises many methodological concerns and suggests avenues for future research. Expand
Pain- and Itch-Related Magnetic Fields
TLDR
It was considered impossible to measure itch-related processing in the brain using MEG, because no itch stimulus was shown to be useful for MEG but a new stimulus to evoke the itch sensation by applying electrical stimuli to the skin was developed. Expand
Evolution from four mental states to the highest state of consciousness: A neurophysiological basis of meditation as defined in yoga texts.
TLDR
This chapter provides a theoretical introduction to states of consciousness and reviews neuroscientific investigations of meditation, an attempt to compile the meditation-related changes in electrophysiological and neuroimaging processes among experienced and novice practitioners. Expand

Cortical representation of the sensory dimension of pain.
TLDR
A double dissociation of cortical modulation indicates a relative specialization of the sensory and the classical limbic cortical areas in the processing of the Sensory and affective dimensions of pain. Expand
Expectation of Pain Enhances Responses to Nonpainful Somatosensory Stimulation in the Anterior Cingulate Cortex and Parietal Operculum/Posterior Insula: an Event-Related Functional Magnetic Resonance Imaging Study
TLDR
It is suggested that ACC and PO/PI are involved in modulation of affective aspect of sensory perception by the uncertain expectation of painful stimulus. Expand
A 15O‐H2O PET study of meditation and the resting state of normal consciousness
TLDR
It is concluded that the H215O PET method may measure CBF distribution in the meditative state as well as during the resting state of normal consciousness, and that characteristic patterns of neural activity support each state. Expand
Effects of distraction on pain perception: magneto- and electro-encephalographic studies.
TLDR
It is suspected that the MEG response, whose dipole is estimated in the bilateral second somatosensory cortex (SII) and insula, reflects the primary activities of pain in humans. Expand
Role of Operculoinsular Cortices in Human Pain Processing: Converging Evidence from PET, fMRI, Dipole Modeling, and Intracerebral Recordings of Evoked Potentials
TLDR
This multimodal study provides cross-validated spatial and temporal information on the pain-related processes occurring in the operculoinsular region, which thus appears as a major site for the early cortical pain encoding in the human brain. Expand
Increased cerebral functional connectivity underlying the antinociceptive effects of hypnosis.
TLDR
Analysis of PET data showed that the hypnotic state significantly enhanced the functional modulation between midcingulate cortex and a large neural network encompassing bilateral insula, pregenual anterior cingulate cortex, pre-supplementary motor area, right prefrontal cortex and striatum, thalamus and brainstem. Expand
A comparative magnetoencephalographic study of cortical activations evoked by noxious and innocuous somatosensory stimulations
TLDR
The results suggested that cortical processing was similar between noxious and innocuous stimulation in SI and SII, but different in insular cortex, and implied that activities in the amygdala/hippocampal formation represented common effects ofNoxious and tactile stimulations. Expand
Cortical representation of pain: functional characterization of nociceptive areas near the lateral sulcus
TLDR
Imaging and electrophysiological studies in humans suggest that parasylvian cortex is activated by painful stimuli, and is one of the first cortical relay stations in the central processing of these stimuli. Expand
Imaging how attention modulates pain in humans using functional MRI.
TLDR
Functional MRI was used to elucidate the underlying neural systems and mechanisms involved in reduced pain perception and showed brain areas associated with the affective division of the anterior cingulate cortex and orbitofrontal regions showed increased activation when subjects were distracted during painful stimulation.

Pain Processing Traced by Magnetoencephalography in the Human Brain
TLDR
The temporal and spatial processing of pain perception in human was traced by MEG and the four-source model was found to be the most appropriate; sources 1 and 2 at the secondary sensory cortex (SII) contralateral and ipsilateral to the stimulation, and sources 3 and 4 at the anterior medial temporal area (probably the amygdalar nuclei or hippocampal formation).
