Neural Correlates of Chanting: A Systematic Review

Wiley Interdisciplinary Reviews: Cognitive Science November 1, 2025 Gemma Perry, Lee Wolff, Nicholas Powers et al. 1 citation

Chanting is an ancient and globally widespread ritualistic practice involving rhythmic vocalization or repetition of words, phrases, or sounds. While previous reviews have considered the neurophysiological impact of meditation and spirituality, chanting has received limited systematic investigation. This review aimed to identify and synthesize neural correlates of chanting, examine...

Knocking at the Doors of Perception: Relating LSD Effects on Low‐Frequency Fluctuations and Regional Homogeneity to Receptor Densities in fMRI

European Journal of Neuroscience November 1, 2025 Paolo La‐torraca‐vittori, Livio Tarchi, Elisa Arrigo et al. 1 citation

Despite a renewed scientific interest in lysergic acid diethylamide (LSD), its local neural effects remain underexplored. This functional magnetic resonance imaging (fMRI) study explored and compared LSD-induced changes in local activity (amplitude of low-frequency fluctuations: ALFF) and local connectivity (regional homogeneity: ReHo), assessing their relationship to regional receptor density....

The Fixation-Projection Framework: A Comparison with other Key Models of Consciousness

Journal of Life Sciences Research and Reviews October 22, 2025 Independent Researcher, Newcastle, NSW 2300, Australia, Robert A Dielenberg

This paper introduces the Fixation-Projection Framework (F-P), a conceptual framework that models the brain as a fixation–projection system. Fixations are defined as functional set points instantiated in biological tissue, from synaptic stabilizations to beliefs, while and projections are cast as the remapping and transmission of fixated content. Based on this, it is argued that the F-P...

Neurobiological and Therapeutic Potential of Psilocybin in Psychiatric Disorders

Journal of Pharma Insights and Research October 5, 2025 M Loganathan, A Saravanakumar, P. Parthiban et al.

Psilocybin, an indoleamine alkaloid derived from various fungal species, is the subject of renewed, rigorous investigation for its therapeutic potential in psychiatry. This compound, a prodrug for the active metabolite psilocin, functions primarily as a partial agonist at the serotonin 2A (5-HT2A) receptor. Its administration within a structured psychotherapeutic context is associated with...

Real-time fMRI neurofeedback modulates auditory cortex activity and connectivity in schizophrenia patients with auditory hallucinations: A controlled study.

Psychiatry Research Neuroimaging October 1, 2025 Clemens C C Bauer, Jiahe Zhang, Francesca Morfini et al.

Auditory hallucinations (AHs) affect 60-80 % of schizophrenia patients and often resist antipsychotic treatment. AHs involve superior temporal gyrus (STG) hyperactivity and disrupted auditory-cognitive control connectivity. Real-time fMRI neurofeedback (NFB) enables voluntary modulation of targeted brain regions. We previously showed STG-targeted NFB with mindfulness meditation reduced STG...

Meditation, psychedelics, and brain connectivity: A randomized controlled resting-state fMRI study of N,N-dimethyltryptamine and harmine in a meditation retreat

Universität Zürich, ZORA September 29, 2025 Klemens Egger, Daniel Meling, Firuze Polat et al.

Both meditation and psychedelics are widely studied for their therapeutic potential in mental health. Recent research suggests potential synergies between mindfulness practice and psychedelics, though empirical studies have primarily focused on psilocybin. This study investigates the distinct and combined effects of mindfulness practice and an ayahuasca-inspired formulation containing...

Exploring aperiodic, complexity and entropic brain changes during non-ordinary states of consciousness

arXiv (Cornell University) September 23, 2025 Victor Oswald, Karim Jerbi, Corine Sombrun et al. preprint

Non-ordinary states of consciousness (NOC) provide an opportunity to experience highly intense, unique, and perceptually rich subjective states. The neural mechanisms supporting these experiences remain poorly understood. This study examined brain activity associated with a self-induced, substance-free NOC known as Auto-Induced Cognitive Trance (AICT). Twenty-seven trained participants...

Effects of Tummo Meditation and Niguma Yoga on Brain Activity.

Hawai'i journal of health & social welfare September 1, 2025 Ira D Zunin, Alexander J Ring, Audrey M Sakamoto et al.

Hatha yoga, Qigong, Tai Chi, all ancient practices of the mind, continue to be studied and recognized for their mental and spiritual benefits. However, Tummo meditation and Niguma yoga, ancient practices with origins in the 8th and 11th centuries from the Himalayan Vajrayana tradition, remain obscure and have yet to be disseminated and studied. Previously only practiced by Vajrayana monks...

Breath-Focused Mindfulness and Compassion Training in Parent-Child Dyads: Pilot Intervention Study.

JMIR Formative Research July 17, 2025 Satish Jaiswal, Jason Nan, Seth Dizon et al. 5 citations

Depression in children is a concerning societal issue and can be associated with poor academic performance, school dropout, and poor overall quality of life. Additionally, child depression is often associated with parallel stress and depression in parents. This scenario highlights the urgent need for the development and implementation of accessible and scalable solutions that may cobenefit...

Neurophysiological features of dream recall and the phenomenology of dreams: Auditory stimulation impacts dream experiences.

Consciousness and Cognition July 1, 2025 Gulshan Kumar, Safoora Naaz, Nahida Jabin et al.

Studies on the electrophysiological and phenomenological aspects of dream experiences provide insight on consciousness during sleep. Whole night polysomnography (PSG) studies were conducted among 29 healthy young participants with high dream recall abilities. Dreams reports were collected during the second night by multiple awakening protocol. On the third night, participants were presented...
