Oscillating Mindfully: Using Machine Learning to Characterize Systems-Level Electrophysiological Activity During Focused Attention Meditation.

Biological Psychiatry Global Open Science March 1, 2025 Noga Aviad, Oz Moskovich, Ophir Orenstein et al.

There has been rapid growth of neuroelectrophysiological studies that aspire to uncover the "black box" of mindfulness and meditation. Reliance on traditional data analysis methods hinders understanding of the complex, nonlinear, multidimensional, and systemic nature of the functional neuroelectrophysiology of meditation states. Thus, to reveal the complex systemic neuroelectrophysiology of...

Evaluating brain spectral and connectivity differences between silent mind-wandering and trance states.

Progress in Brain Research May 26, 2023 Helané Wahbeh, Cedric Cannard, Michael Kriegsman et al.

Trance is an altered state of consciousness characterized by alterations in cognition. In general, trance states induce mental silence (i.e., cognitive thought reduction), and mental silence can induce trance states. Conversely, mind-wandering is the mind's propensity to stray its attention away from the task at hand and toward content irrelevant to the current moment, and its main component is...

What if consciousness is not an emergent property of the brain? Observational and empirical challenges to materialistic models

PsyArXiv June 18, 2022 Helané Wahbeh, Dean Radin, Cedric Cannard et al. preprint

The nature of consciousness is considered one of the most perplexing and persistent mysteries in science. We all know the subjective experience of consciousness, but where does it arise? What is its purpose? What are its full capacities? The assumption within today’s neuroscience is that all aspects of consciousness arise solely from interactions among neurons in the brain. However, the origin...

Examining implicit beliefs in a replication attempt of a time-reversed priming task.

F1000Research January 6, 2021 Marilyn Schlitz, Arnaud Delorme

Background: Psi research is a controversial area of science that examines telepathy, clairvoyance, precognition, and psychokinesis (mind over matter). Central to the debate over the existence of psi is of whether independent investigators can replicate reportedly successful psi experiments. One important variable involves the beliefs of experimenters and participants. A preregistered experiment...

Meditation and the Wandering Mind: A Theoretical Framework of Underlying Neurocognitive Mechanisms.

Perspectives on Psychological Science 2021 Tracy Brandmeyer, Arnaud Delorme

During the practice of meditation, the tendency of the mind to wander away from the object of focus is ubiquitous. The occurrence of mind wandering in the context of meditation provides individuals a unique and intimate opportunity to closely examine the nature of the wandering mind by cultivating an awareness of ongoing thought patterns, while simultaneously aiming to cultivate equanimity...

Far less research has been conducted on more challenging domains to measure, such as group and...

Reduced mind wandering in experienced meditators and associated EEG correlates.

Experimental Brain Research September 2018 Tracy Brandmeyer, Arnaud Delorme

One outstanding question in the contemplative science literature relates to the direct impact of meditation experience on the monitoring of internal states and its respective correspondence with neural activity. In particular, to what extent does meditation influence the awareness, duration and frequency of the tendency of the mind to wander. To assess the relation between mind wandering and...

Increased Gamma Brainwave Amplitude Compared to Control in Three Different Meditation Traditions.

PLoS One 2017 Claire Braboszcz, B Rael Cahn, Jonathan Levy et al.

Despite decades of research, effects of different types of meditation on electroencephalographic (EEG) activity are still being defined. We compared practitioners of three different meditation traditions (Vipassana, Himalayan Yoga and Isha Shoonya) with a control group during a meditative and instructed mind-wandering (IMW) block. All meditators showed higher parieto-occipital 60-110 Hz gamma...

Electrocortical activity associated with subjective communication with the deceased

Frontiers in Psychology 2013 Arnaud Delorme, Julie Beischel, Leena Michel et al. 47 citations

During advanced meditative practices, unusual perceptions can arise including the sense of receiving information about unknown people who are deceased. As with meditation, this mental state of communication with the deceased involves calming mental chatter and becoming receptive to subtle feelings and sensations. Psychometric and brain electrophysiology data were collected from six individuals...

Electrocortical activity prior to unpredictable stimuli in meditators and nonmeditators.

Explore 2011 Dean Radin, Cassandra Vieten, Leena Michel et al.

Advanced meditators occasionally report experiences of timelessness, or states of awareness that seem to transcend the usual boundaries of the subjective present. This type of experience was investigated in eight experienced meditators and eight matched controls by measuring 32 channels of EEG before, during, and after exposure to unpredictable light and sound stimuli. The experiment postulated...
