Standardized mindfulness practices that focus attention on breath and body sensations may work by training the brain to better regulate alpha rhythms (7-14 Hz) in the primary somatosensory cortex. These alpha rhythms filter sensory information entering the neocortex. The framework suggests that in chronic pain, somatic attention in mindfulness reduces pain-focused attentional resources by altering alpha activity. In depression relapse prevention, somatic attention competes with rumination, as internal cognitive processes rely on alpha filtering. A computational model predicts enhanced top-down modulation of alpha through precise timing changes in thalamocortical inputs. The theory aligns with Buddhist teachings that mindfulness begins with mindfulness of the body, proposing that enhanced alpha regulation improves detection and regulation of mind-wandering.

This review synthesizes evidence on the relationship between resting-state fMRI functional connectivity and mindfulness in both clinical and non-clinical populations. The authors find that mindfulness practice is associated with altered functional connectivity in brain networks involved in attention, self-referential processing, and emotion regulation. These changes may underlie the psychological benefits of mindfulness, but the review notes that the current evidence is mixed and limited by heterogeneous methodologies and small sample sizes.

About half of the millions of people who learn mindfulness meditation continue regular practice after initial instruction, but it is unclear whether benefits increase with ongoing practice or whether harm can occur. Evidence shows a wide range of experiences from positive to challenging and potentially harmful. Complex interactions and temporal sequences may explain these experiences and their links to health and well-being. Effects may vary systematically due to factors like initial dosage, accumulated practice, developing skill, and interactions with past experiences and environment. The authors call for interdisciplinary, ontologically agnostic research using longitudinal models and insights from contemplative traditions to develop safer, more effective applications.

A 12-week mindfulness course increased recall of positive words and improved psychological well-being in university students compared to an active control (music) course. Greater positive word recall was linked to higher well-being and lower depression and anxiety. Mindfulness training may enhance well-being by altering how emotional information is processed, though self-selection could have influenced results.

Classifying meditation techniques is crucial for research but faces fundamental challenges. This paper describes problems in defining meditation and suggests an integrated model. Drawing on classical, contemporary, and holistic systems, it proposes that all meditation techniques involve a specific set of activities: focusing, releasing, imagining, and moving in relation to an object of meditation or fields of experience. These activities can be combined and unified into observing, producing, and being aware, and all are unified in awareness of awareness. Defining specific techniques involves specifying which activities and objects are involved. This approach can account for the inner workings of existing classification systems, laying a foundation for an overarching system to guide future research and practice.

Meditation practitioners report being able to induce a total absence of consciousness lasting up to seven days, known as cessation or nirodha samāpatti. Unlike sleep, individuals in this state cannot be woken by external stimulation, experience no sense of time or tiredness, and have a stiff rather than relaxed body. Emerging from cessation is said to produce profound effects such as sudden clarity, openness, and insights. This paper outlines the historical context, presents preliminary data from two labs, sets a research agenda, and provides an initial framework for understanding these experiences. It integrates classical Buddhist concepts of nirodha and nirodha samāpatti into current cognitive-neurocomputational and active inference frameworks of meditation.

Jhanas are profound meditative states that can deconstruct ordinary consciousness, according to a case study of an adept meditator. Using 4 hours of 7T fMRI data collected across 27 sessions, the study identified distinctive brain activity patterns in cortical, subcortical, brainstem, and cerebellar regions during jhana meditation. Correlations between brain activity and phenomenological qualities of attention, jhanic qualities, and narrative processing showed that jhanas differ from non-meditative states. The findings suggest jhana practice offers unique insights into consciousness and potential benefits for mental health and well-being.

Incongruities between meditator self-reports and objective measurements (e.g., of brain states) hamper research into meditation-related emergent phenomenology. Key theories from Buddhist contemplative traditions are translated into scientific terms and systematized as a functionalist model of the mind—the Thin Model—which demonstrates immediate explanatory power. The model's nested nature allows explanations to be restricted to specific problems, connecting complex higher-level phenomena like self-reports to lower-level phenomena like brain states without requiring simplistic assumptions. A detailed demonstration shows how the model converts subjective accounts of ecstatic meditative states (jhānas) into testable neuroscientific hypotheses. The Thin Model offers an organizing principle for explanations of mental phenomena and may be relevant to other fields.

Greater trait mindfulness, measured by self-report scales, is consistently linked with reduced amygdala reactivity to emotional stimuli, increased cortical thickness in frontal and insular regions, and decreased connectivity within the default-mode network, converging with findings from intervention studies and mindfulness experts. However, associations with EEG metrics and between-network resting-state fMRI remain inconclusive. The authors recommend larger samples, multivariate approaches, and careful reliability testing, urging a move away from simplistic explanations of mindfulness and brain function.

Meditation and psychedelics both appear to alter self-referential processing, potentially leading to experiences of self-transcendence. This review examines whether scientific investigation of self-transcendence through these methods has clinical relevance. The authors suggest that changes in self-referential processing may underlie therapeutic benefits for mental health conditions, though the exact mechanisms remain unclear. The paper argues that understanding how meditation and psychedelics modulate the sense of self could inform new treatments for disorders characterized by maladaptive self-focus, such as depression and anxiety.

Advanced concentrative absorption meditation, such as the jhanas, involves volitional mental absorption that can be scientifically studied. This paper argues that these states represent a distinct category of meditative experience characterized by deep, effortless focus and profound well-being. It proposes a scientific framework for understanding these measurable states of consciousness, drawing on existing research to outline how absorption, concentration, and positive outcomes like well-being can be systematically investigated. The authors suggest that developing a rigorous scientific approach to jhana and similar practices could bridge contemplative traditions and consciousness research, offering new insights into the nature of deep meditative states and their potential benefits.

A single advanced meditator with over 6,000 hours of retreat mindfulness training experienced 37 cessation events—dramatic moments of profound clarity and equanimity involving a complete break in experience—while EEG was recorded. From 21 seconds before each cessation, whole-brain functional connectivity in the alpha band decreased linearly, then returned to prior levels over the 40 seconds following. The decrease was driven by frontal-to-left-temporal and posterior connections, while the recovery involved widespread increases. No change in network integration was observed. These findings provide neuroscientific evidence of large-scale brain modulation during cessation events, laying groundwork for future studies of advanced meditation.

Hypnotizability, a stable trait in adulthood, is linked to the concentration of the neurotransmitter GABA in the anterior cingulate cortex (ACC). In healthy individuals, higher ACC GABA levels were positively associated with higher hypnotizability scores measured by the Hypnotic Induction Profile. An exploratory analysis also found a negative relationship between glutamate levels and the absorption and imaginative involvement subscale of the Dissociative Experiences Scale. These findings suggest a neurobiological basis for individual differences in hypnotic responsiveness, which may help explain variability in treatment outcomes for hypnosis-based psychotherapies.

In an adept practitioner performing jhana meditation over 5 days inside a 7 Tesla MRI scanner (27 runs), the thalamus and several cortical networks—somatomotor, limbic, default-mode, control, and temporo-parietal—showed good within-subject reliability across all jhanas. When fMRI measurements were adjusted for variability in self-reported phenomenology, other networks such as attention and salience showed noticeable increases in reliability. The findings provide a preliminary template of reliable brain areas likely underpinning core neurocognitive elements of jhana meditation and highlight the value of neurophenomenological designs for characterizing neuronal variability in advanced meditative states.

Long-term meditators provide a way to study how extensive meditation training affects the autonomic nervous system. Research has described a state of 'relaxed alertness' with both sympathetic and parasympathetic activation, but findings vary widely, showing either branch alone, both, or shifting patterns. This review synthesizes these inconsistent results by considering three factors: the specific style of meditation, the meditator's expertise level, and within-practice variations. Accounting for these factors reveals consistent patterns, shifting from 'long-term' to a more precise 'advanced' meditation concept that highlights skills and stages. Specific heart rate variability patterns, including very low and low-frequency spectral power peaks and cardiac-respiratory coupling, emerge, which can inform improved meditation training.

Advanced meditation states known as Jhanas, achieved through concentration absorption, are associated with distinct patterns of brain activity and subjective experience. In an intensive case study of an experienced meditator, each Jhana state showed unique neural signatures, including changes in gamma power, alpha desynchronization, and connectivity between frontal and parietal regions. These findings suggest that Jhana states are not merely variations of ordinary mindfulness but involve specific, reproducible neurophenomenological profiles. The work demonstrates that deep meditative absorption can be systematically studied using multimodal brain imaging and first-person reports, providing a foundation for understanding altered states of consciousness.

Network neuroscience examines brain organization by mapping connections between its elements. This review describes how mindfulness meditation may alter structural and functional brain networks. Although evidence is preliminary, studies suggest mindfulness shifts connector hubs—the anterior cingulate cortex, thalamus, and mid-insula—and reduces intraconnectivity within the default mode network. Global connectivity findings are mixed. The authors call for rigorous study designs, open science, and diverse samples to better understand mindfulness's impact on brain networks.

A 21-day self-directed digital course (DIPP) was co-designed to improve psychedelic preparation. The intervention, built on a four-factor model of psychedelic preparedness, was developed through two mixed-methods studies: interviews with 19 past high-dose psilocybin retreat attendees and co-design workshops with 28 current retreat participants. The course includes daily meditation, weekly module exercises, and mood tracking. The authors suggest DIPP offers a scalable, comprehensive tool to enhance safety and therapeutic benefits by addressing knowledge, psychophysical readiness, safety planning, and intention.

The stages of insight (SoI) are a series of psychological realizations experienced during advanced investigative insight meditation (AIIM). In a case study of one adept meditator who underwent 4 hours of 7T functional magnetic resonance imaging (fMRI) across 26 runs with concurrent phenomenological reports, distinct whole-brain activity patterns were identified for specific SoI, differing from non-meditative control states. SoI consistently deactivated brain regions involved in self-related processing, such as the medial prefrontal cortex and temporal poles, while activating areas linked to awareness and perception, including parietal and visual cortices, caudate, brainstem nuclei, and cerebellum. Patterns of brain activity related to affective processing and SoI phenomenology were also observed. This provides the first neurophenomenological evidence that SoI shifts and deconstructs self-related perception and conceptualization, increasing general awareness and perceptual sensitivity.

Research on meditation and mindfulness has progressed through two waves: the first focused on clinical benefits, the second on methodological rigor and potential negative effects. A third wave is now needed to investigate transformative psychological growth from advanced meditation, where challenging experiences may be essential for development. Defining negative effects is difficult from contemplative perspectives. The authors distinguish objective from subjective happiness and define a negative effect as something that contributes to overall unhappiness in both senses. This framework integrates psychological and contemplative views, arguing that what seems negative may be part of meditative growth.

Advanced concentrative absorption meditation produces distinct, distributed brain-wide activity patterns that differ from ordinary consciousness, as shown by ultrahigh-field 7T fMRI in a single expert meditator. Using geometric eigenmode decomposition, the study found elevated global brain state power and energy during meditation compared to control tasks, with mid-frequency brain state power and energy following a non-random, cubic trajectory across the meditation sequence. These brain state differences correlated with subjective reports of attention, meditation quality, and sensations. The findings reveal similarities and differences between advanced meditation and psychedelic-induced states, offering insights into refined conscious states and their implications for well-being.

Aesthetic chills—pleasurable, cold sensations—are linked to self-transcendence, a state of ego-dissolution and connectedness that promotes well-being and prosociality. In a diverse sample of 2937 participants in Southern California exposed to chills-eliciting stimuli, both the likelihood and intensity of chills were positively associated with measures of self-transcendence, even after accounting for demographics, traits, and prior mood. Analyses of variance, mutual information, and correlation structure confirmed reliable interrelations across various audiovisual stimuli. The findings suggest aesthetic chills may indicate sufficiently intense feelings of self-transcendence, though generalizability to non-WEIRD populations and causal direction require further study.

Long-term meditators show a distinct pattern of cognitive and neural changes from prolonged mindfulness practice, including enhanced sensory integration, reduced negative emotional responses to pain, more rational decision-making, and altered self-awareness. Neuroimaging reveals increased activation in brain networks linked to interoception and pain (salience network), reduced connectivity between executive and salience networks, diminished fear and amygdala activation, and altered default-mode network activity associated with emotional neutrality and non-ordinary states of consciousness. Methodological limitations prevent firm conclusions about lasting trait effects, and a unified neurophenomenological framework is needed to systematically study advanced meditation's states and stages.

Focused attention meditation (FA) involves concentrating on a specific object, like the breath, while letting go of distractions. This scoping systematic review examined EEG and MEG studies on FA to clarify how these studies are designed and what they found about brain activity. The review found that participant characteristics varied widely across studies, which may explain inconsistent results, while the types of meditation tasks and control conditions used were fairly similar. Consistent neurophysiological trends show that FA is linked to increased brainwave power in alpha, beta, and gamma bands, along with higher neural complexity and reduced criticality. The review recommends methodological improvements and notes gaps, such as limited MEG use and a lack of longitudinal studies.
