EEG brain reconfiguration during meditation-induced extended cessation of consciousness: A dense-sampling multi-participant microstate study

bioRxiv Preprint Server February 10, 2026 David Zarka, Winson F.z. Yang, Abel Rassat et al. preprint

Extended cessation (EC) is a rare, non-ordinary meditative endpoint characterized by a temporary absence of reportable phenomenal experience, followed by an extraordinary perceptual vividness, openness, equanimity and affective balance. EC thus offers a unique, non-pharmacological window into the brain dynamics underlying suspension of conscious experience and the subsequent psychological...

The neuroscience of highly stable, positive, and refined states of consciousness during jhana-type advanced concentration absorption meditation (ACAM-J).

bioRxiv : the preprint server for biology November 13, 2025 Winson F.z. Yang, Ruby M. Potash, Grace Mackin et al. preprint

Humans can experience a rich array of conscious experience, including highly stable, positive, and refined states of non-ordinary perception that can be elicited through advanced meditation. Here, we present the first group-level, ultra-high-field (7T) fMRI study of jhana advanced concentration absorption meditation (ACAM-J). We combined local (regional homogeneity), mesoscale (connectivity...

Whole-Brain Models of Advanced Concentrative Absorption Meditation: Approaching Critical Dynamics through Jhāna

bioRxiv September 25, 2025 Jakub Vohryzek, Edmundo Lopez-Sola, Winson F.z. Yang et al. preprint

Advanced meditation offers a powerful lens for investigating consciousness and for understanding how sustained training may contribute to human flourishing. In the spirit of neurophenomenology, we combine first-person reports with model-free empirical analyses and formal whole-brain modeling to investigate the mechanisms underlying advanced meditative states and minimal phenomenal experience...

Neuroelectrophysiological correlates of extended cessation of consciousness in advanced meditators: A multimodal EEG and MEG study

bioRxiv Preprint Server September 19, 2025 Kenneth Shinozuka, Winson F.z. Yang, Ruby M. Potash et al. 3 citations preprint

In some contemplative traditions, “extended cessation” (EC) refers to a state of advanced meditation in which the meditator intentionally suppresses their own consciousness and re-emerges with a profound sense of clarity and equanimity. Here, we present the first electrophysiological study of EC, in which five meditators underwent concurrent electroencephalography (EEG) and...

Endogenous suspension and reset of consciousness: 7T fMRI brain mapping of the extended cessation meditative endpoint

bioRxiv Preprint Server September 6, 2025 Winson F.z. Yang, Akila Kadambi, Kilian Abellaneda-Pérez et al. 4 citations preprint

Extended cessation (EC), an advanced meditative state in which consciousness is volitionally suspended and later reset with immense mental clarity, equanimity, and peace, offers an endogenous model for investigating the mechanisms of consciousness. Using ultra-high-resolution 7T fMRI with dense within-subject sampling (N=3), we quantified whole-brain activity, functional and effective...

Integrated Phenomenology and Brain Connectivity Demonstrate Changes in Nonlinear Processing in Jhana Advanced Meditation.

Journal of Cognitive Neuroscience May 14, 2025 Ruby M. Potash, Sean D. Van Mil, Mar Estarellas et al. 7 citations

We present a neurophenomenological case study investigating distinct neural connectivity regimes during an advanced concentrative absorption meditation called jhana (ACAM-J), characterized by highly stable attention and mental absorption. Using EEG recordings and phenomenological ratings (29 sessions) from a meditator with +20,000 hr of practice, we evaluated connectivity metrics tracking...

Investigating the complex cortical dynamics of an advanced concentrative absorption meditation called jhanas (ACAM-J): a geometric eigenmode analysis.

Cerebral cortex (New York, N.Y. : 1991) February 5, 2025 Ruby M. Potash, Winson F.z. Yang, Brian Winston et al. 11 citations

Advanced meditation has been associated with long- and short-term psychological changes such as bliss, profound insight, and transformation of well-being. However, most advanced meditation neuroimaging analyses have implemented primarily spatially-localized approaches, focusing on discrete regional changes in activity rather than distributed dynamics. The present study uses a geometric...

Neuromodulation and meditation: A review and synthesis toward promoting well-being and understanding consciousness and brain.

Neuroscience and Biobehavioral Reviews August 1, 2024 Kilian Abellaneda-Pérez, Ruby M. Potash, Á. Pascual-Leone et al.

The neuroscience of meditation is providing insight into meditation's beneficial effects on well-being and informing understanding of consciousness. However, further research is needed to explicate mechanisms linking brain activity and meditation. Non-invasive brain stimulation (NIBS) presents a promising approach for causally investigating neural mechanisms of meditation. Prior NIBS-meditation...
