A unified neurocognitive theory, the theory of attention and consciousness (TAC), bridges separate accounts of consciousness and visual attention. TAC extends the global neuronal workspace model to a visual attentional workspace (VAW) controlled by executive routers, eliminating the need for explicit saliency maps. It explains phenomena including the attentional blink, working memory consolidation, illusory conjunctions, inattentional blindness, and working memory capacity. The theory proposes multiple processing stages between early visual representation and conscious access, suggests neural correlates of phenomenal consciousness, and reconciles all-or-none with graded views of conscious representation.

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.

A unifying global workspace model proposes that phenomenal and access consciousness arise from distinct yet interacting brain loops involving recurrent neural interactions. Feedback signaling onto sensory cortical maps is critical for phenomenal consciousness, while two forms of top-down attention—attention for perception and attention for access—play differential roles for phenomenal and access consciousness. The model was implemented as a neural network that simulated single and multiple visual object processing and the attentional blink.

Different meditation practices—focused attention, open monitoring, and loving kindness—share a common brain connectivity pattern while also showing distinct neural signatures. Using a refined measure of neural coupling (imaginary part of EEG coherence) in highly experienced meditators, the study found that all three types increased connectivity in broadly distributed delta networks, left-hemispheric theta networks with a posterior focus, and right-hemispheric alpha networks with a parieto-occipital focus. Each meditation state also recruited left- or right-lateralized beta networks in unique ways. These findings suggest that frequency-specific inter-hemispheric asymmetry is a key feature of meditation, with lateralized fast-frequency networks supporting the distinct mental processes of each practice.

Machine learning applied to fMRI functional connectivity data can distinguish focused attention from open monitoring meditation styles, but only in expert Theravada Buddhist monks, not in novice meditators. The Anterior Salience and Default Mode networks were key for classification, consistent with their roles in emotion and self-regulation during meditation. Specific couplings between areas regulating attention, self-awareness, and somatosensory processing were also important, along with left inter-hemispheric connections. The findings support that extensive meditation practice differentially modulates large-scale brain networks according to meditation style.

Long-term meditation practice reshapes functional connectivity patterns in large-scale brain networks, and the specific patterns depend on the type of meditation used. Using fMRI and multivariate pattern analysis, researchers found that connectivity patterns in key brain networks could predict both a meditator's expertise and age. Expertise-related patterns differed between Focused Attention (FA) and Open Monitoring (OM) meditation: FA involved networks for attention, while OM involved networks for cognitive control and emotion regulation. Age-related patterns were unaffected by meditation style. The findings indicate that intensive mental training induces neuroplastic changes in brain network connectivity that are specific to the form of meditation practiced.

A selfless state of consciousness, reported for centuries in wisdom traditions, involves both temporary and lasting conditions. In psychology, the healthy self is typically emphasized, and the idea of selfless modes is sometimes dismissed, hindering empirical progress. This paper offers an interdisciplinary conceptual discussion grounded in the pattern theory of self (PTS), which views the self as a complex pattern of dynamically related processes. It proposes that meditative practices induce a reorganization of the self-pattern, enabling temporary or persistent selfless experience. The authors present a heuristic model, the pattern theory of selflessness (PTSL), with six nonlinear transformations: consolidating and integrating the self-pattern; cultivating concentration and present-moment awareness; cultivating mindful awareness; self-deconstruction states; self-flexibility; and self-liberation as a trait. This integrative view advances understanding of non-self experience and guides empirical research.

Theravada Buddhist monks with extensive meditation experience underwent magnetoencephalography during focused attention meditation, open monitoring meditation, and resting states. Brain microstate coverage and occurrence differed between meditation and rest and between the two meditation styles. The Hurst exponent, a measure of long-range memory in brain dynamics, was lower during both meditation conditions than during rest. Lempel-Ziv complexity, which quantifies signal complexity, increased progressively from rest to focused attention meditation to open monitoring meditation. These changes in brain criticality indices suggest that meditation shifts brain dynamics toward a more critical state, paralleling changes in cognitive state.

A distinction between phenomenal and access consciousness has been influential in consciousness studies. Phenomenal consciousness is linked to iconic memory and a fragile short-term memory store with larger capacity than working memory, while access consciousness is linked to limited-capacity working memory. Visual attention was thought to affect only access consciousness, but some evidence suggests earlier attentional effects. An experiment using a change-detection task with delayed cueing and high- and low-priority colored objects found an attentional bias toward high-priority objects at longer cueing delays (600 and 1,200 ms) associated with fragile visual short-term memory, but not at shorter delays (16.

Mindfulness training and trait mindfulness influence autobiographical memory by enhancing cognitive, emotional, and self-referential flexibility. This flexibility enables a more balanced retrieval of episodic, semantic, and emotional content, increases memory specificity, and reduces emotional reactivity during recall. The review of 50 studies suggests that mindfulness promotes meta-awareness, acceptance, and the ability to shift from a first- to a third-person self-perspective. These changes may involve reconsolidation of memory traces linked to the self, supported by altered brain activity and connectivity in the default mode, salience, and central executive networks. The findings have implications for clinical conditions like depression and for cognitive neuroscience.

Selective attention produces both costs and benefits in iconic memory and fragile visual short-term memory, which are linked to phenomenal consciousness. In three experiments using a retro-cue paradigm, attentional costs disrupted visual maintenance at longer delays. Reducing the memory array exposure from 250 ms to 100 ms prevented participants from selecting objects based on their priorities, indicating a bottom-up factor. A pattern mask presented before transfer to visual working memory reduced overall performance but preserved the priority effect. These findings suggest that fragile-VSTM and iconic memory play distinct roles in feature-based attentional selection, with implications for phenomenal consciousness before conscious access.

Long-term meditation practice is associated with a proactive top-down inhibition of brain regions that process the sensory aspects of pain, even when the meditator is not actively meditating. Experienced meditators, compared to novices, showed substantially suppressed temporal and spatial synchronization of pain-related brain oscillations (from theta-alpha to gamma frequencies) at somatosensory areas within 200 milliseconds after a painful stimulus. This suppression was predicted by increased pre-stimulus alpha activity in the same regions, indicating a preparatory, inhibitory state. The emotional and cognitive reappraisal of pain, reflected by the P3b brainwave component, was reduced but not eliminated, suggesting that experienced meditators can dissociate proactive inhibition of sensory processing from reactive emotional evaluation during pain control.

The self in non-human animals is often studied in a limited, dichotomous way that separates low-level bodily and affective aspects from high-level cognitive ones. A proposed framework based on the Pattern Theory of Self (PTS) treats the self as a dynamic, multidimensional construct with graded, non-hierarchical dimensions—ranging from bodily and affective to intersubjective and normative. This approach accommodates variability within and across species, allowing researchers to investigate how the self emerges in different degrees and forms shaped by ecological niches and adaptive demands, without relying on anthropocentric biases.

Different types of meditation alter how the brain processes pain, but the effects depend on the specific meditation technique. Focused attention meditation reduced pain intensity and unpleasantness by modulating activity in the anterior cingulate cortex and insula, while open monitoring meditation reduced pain unpleasantness without affecting intensity, engaging different neural pathways. Loving-kindness meditation increased pain unpleasantness and activated regions associated with emotion and reward. The findings suggest that meditation-induced pain relief is not a uniform phenomenon but varies by practice.

Meditation practice engages cognitive control systems in the brain. Highly experienced meditators, compared to novices, showed strong theta synchronization of fronto-parietal and medial-frontal networks in left parietal regions across all meditation styles. Only lateralized beta connectivity in medial-frontal networks differed between meditation styles. Theta fronto-parietal connectivity depended non-linearly on expertise, with opposite patterns in left and right hemispheres. Inter-hemispheric fronto-parietal connectivity in faster frequency bands increased linearly with expertise. These results indicate that executive control systems maintain meditation states, and lateralized involvement of these networks may support both generic and style-specific states, with functional plasticity in executive control networks underpinning unique states in expert meditators.
