Long-term mindfulness meditation can alter self-awareness by reducing identification with a static self. A study of 12 experienced meditators used magnetoencephalography and first-person reports to distinguish two types of self-awareness: narrative self-awareness, which involves weaving memories and plans into a coherent identity, and minimal self-awareness, focused on present-moment experience. Attenuating narrative self-awareness corresponded to decreased gamma-band power in frontal and medial prefrontal regions. Attenuating minimal self-awareness involved decreased beta-band power in a network including ventral medial prefrontal, medial posterior, and lateral parietal regions. The experience of selflessness was linked to decreased beta-band activity in the right inferior parietal lobule.

Based on detailed self-reports from a long-term mindfulness practitioner with about 20,000 hours of meditation experience, the sense of boundaries (SB) can shift through three stages: default, dissolving, and disappearing. During these shifts, seven overlapping categories change, including senses of internal versus external, time, location, self, agency, ownership, and the first-person perspective. Two categories—the touching/touched structure and bodily feelings—persist even when the SB disappears entirely. The findings suggest that the sense of boundaries is not a single, fixed experience but a composite of multiple, separable dimensions that can be altered through meditative practice.

Neurophenomenology integrates first-person (subjective) and third-person (objective) approaches to the mind. This practical guide outlines theoretical principles, the importance of phenomenological training, and the utility of cooperating with meditators as skilled participants. First-person accounts range from thick to thin phenomenology, highlighting a tension in naturalizing phenomenology. A typology of bridges creates mutual constraints between approaches. The paper demonstrates a decade of neurophenomenological studies investigating the sense of self, focusing on its embodied and minimal aspects accessed via dissolution of sense-of-boundaries, revealing the multi-dimensionality and flexibility of embodied selfhood.

The sense of being a self separate from the world can vary in intensity, is linked to specific brain activity, and can be altered through meditation. A long-term meditation practitioner deliberately produced three mental states with different degrees of self-boundary experience while undergoing magnetoencephalography. The results were partly confirmed in ten other experienced meditators. Right-lateralized beta oscillations in the temporo-parietal junction, which supports the unity of self and body, and in the medial parietal cortex, a key self-representation area, were implicated. The graded, flexible nature of self-specific processes may have clinical relevance for people with disturbed self-boundaries.

A fundamental aspect of the sense of self is its pre-reflective dimension, which specifies the self as a bounded and embodied knower and agent. Deep meditative states involving global dissolution of the sense of self offer a promising path for investigating this elusive feature. A comprehensive phenomenological inquiry into meditative self-boundary alteration systematically characterized induced states by changes in six experiential features: sense of location, agency, first-person perspective, attention, body sensations, and affective valence, along with their interaction with meditative technique and overall degree of dissolution. Quantitative analyses highlighted a unitary dimension of boundary dissolution.

A theoretical model called the consciousness state space (CSS) proposes that all experiences can be mapped along three dimensions: time, awareness, and emotion. These dimensions each have two layers: a core layer tied to the present moment and minimal selfhood, and an extended layer supporting narrative selfhood, memory, and personal identity. The model suggests that normal waking consciousness involves two simultaneous, typically antagonistic trajectories within core and extended consciousness. Altered self-states, such as flow and meditation, change this dynamic. The CSS framework integrates diverse phenomenological and neuroscientific findings, offering testable predictions for the science of consciousness.

Rigidity, or inflexibility, is a core feature of transdiagnostic processes underlying many mental health disorders. The pattern theory of self (PTS) defines the self as a dynamic, nonlinear pattern of multiple interacting processes. Mindfulness-Based Interventions (MBIs) can reduce rigid, habitual self-patterns, thereby improving mental health. MBIs alter psychological and behavioral aspects of the self-pattern and can shift the entire self-pattern as a gestalt. Neuroscientific evidence shows that the phenomenology of the self is reflected in cortical networks, and meditation alters these networks. Combining PTS and neuroscientific findings may deepen understanding of psychopathology and improve diagnosis and treatment.

Four weeks of daily Quadrato Motor Training (QMT), a whole-body movement contemplative practice, increased cognitive flexibility and ideational fluency more than verbal or simple motor training alone. In a pilot longitudinal MRI study, gray matter volume and fractional anisotropy changes in several brain regions, including the cerebellum, correlated positively with cognitive flexibility scores. These preliminary results support a connection between motor practice and creativity, consistent with models integrating cognitive flexibility, embodiment, and the motor system.

Long-term meditators can intentionally reduce the sense of being an embodied self, and this change is linked to decreased high-beta brain activity in the posterior medial cortex. In a study of 46 experienced meditators (19 female, 27 male) who underwent magnetoencephalographic monitoring, those who reported radical disruptions of embodied self-experience—such as loss of agency and a localized first-person perspective—showed the strongest neural reductions. These neural changes correlated with lifetime meditation experience and interview-based reports of experiential shifts, but not with standard self-report questionnaires. The findings suggest that posterior medial cortex oscillations are central to supporting the embodied sense of self.

The neurophenomenology research program, pioneered by Varela, rigorously examines subjective experience using first-person methodologies inspired by phenomenology and contemplative practices. This review explores recent advancements, particularly their application to meditation practices and potential clinical translations. It examines innovative multidimensional phenomenological assessment tools designed to capture subtle, dynamic shifts in experiential content and structures of consciousness during meditation, shedding light on mechanisms and trajectories of meditation practice.

More than half of people who participate in ayahuasca ceremonies report having a subjective sense of death during the experience, termed Ayahuasca-induced Personal Death (APD). These experiences are typically strong and transformative, associated with an increased sense of transcending death and greater certainty that consciousness continues after death. APDs are not linked to demographics, personality, or psychopathology, but are associated with greater environmental concern, improved ability to cope with life problems, and a heightened sense of life fulfillment. The findings suggest these death experiences may be a mechanism for psychedelics' long-term positive effects.

Meditators' brains show acceptance rather than denial when processing death-related stimuli linked to the self, as measured by a magnetoencephalogram visual mismatch-response (vMMR) paradigm. This neural shift corresponds with increased self-reported well-being and is associated with positively valenced experiences of self-dissolution during meditation. The findings suggest that the brain's defensive response to mortality is not fixed but can be reduced through insight meditation grounded in mindful awareness, which trains acceptance of impermanence. The results also indicate that addressing mortality concerns is important when interventions may disrupt self-consciousness.

A scoping review of neural complexity in meditation finds that, during meditation, brain activity shows higher complexity compared to waking rest or mind-wandering, while regular meditation practice is associated with decreased baseline complexity as a long-term trait. The review disentangles different families of complexity measures, distinguishes short-term state effects from long-term trait effects, and considers differences among meditation styles. It provides a framework to guide debates and offers practical guidelines for future research on complexity and consciousness.

Long-term meditators show enhanced low-level prosocial capacities, including better emotion recognition and reduced outgroup bias, compared to non-meditators. A neural index of self-boundary flexibility, measured via high beta deactivation, remained stable over a year and negatively correlated with recognizing negative emotions, suggesting a link to reduced social threat perception. The study involved 44 long-term meditators and 53 controls. These findings connect the neural correlates of self-boundary flexibility to prosociality, supporting the idea that flexing self-boundaries through meditation may enhance prosocial traits.

People who regularly use ayahuasca show lower death anxiety, less fear of death, less avoidant behavior around death, and greater acceptance of death compared to non-users. A cross-sectional study of 54 ayahuasca veterans and 53 non-users measured these differences using questionnaires and behavioral tasks. The differences were not explained by demographics, personality, mindfulness, beliefs about the afterlife, or awareness of impermanence. Instead, acceptance of impermanence—the willingness to embrace life's transience—was the key mechanism. Among ayahuasca users, the intensity of lifetime ego-dissolution experiences predicted how much they accepted impermanence. This suggests that acute psychedelic experiences can foster lasting changes in how people process mortality, and that promoting impermanence acceptance may help manage existential fear.

Meditation research has rarely examined how brain structure, function, and self-reports relate. This study demonstrates such a relationship for Mindfulness meditation (MM), which aims to reduce thought-related processes and enhance bodily awareness, thereby reducing identification with thought content and deconstructing maladaptive self-schema. The authors hypothesized that the structure of default mode network (DMN) regions, associated with spontaneous thoughts and self-representation, would negatively correlate with MM experience and self-reported positive affect, while positively correlating with DMN resting-state function.

correction
A correction was issued for a published article: the average number of ayahuasca uses in the ayahuasca group was revised from 69.4 to 55.7 (standard deviation 82.1). Participants had used ayahuasca 5.2 times more than psilocybin, 4.6 times more than mescaline, and 5.6 times more than LSD. The authors state the error does not alter the scientific conclusions.
