Psychedelic experiences, especially those induced by substances such as N,N-Dimethyltryptamine (DMT), are often characterized by high subjective intensity, complex visual content, and notable ineffability-that is, the difficulty of being fully expressed in words. This expressive limitation poses a significant challenge to the integration of the experience, which is essential for the therapeutic...

Existential and spiritual suffering are frequently reported by individuals facing serious illnesses, particularly at the end of life, and are associated with diminished quality of life, increased psychological distress, and requests for hastened death. While Palliative Care (PC) aims to provide holistic support, existing therapeutic options often fail to adequately address the profound...

Chronic loneliness is a risk factor for physical and health problems, in part due to dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis and sympathetic nervous system. In contrast, temporary moments of positive solitude (passing good times alone and not feeling lonely) appear to have positive effects on mental health, social life, and creativity, and seems to be a buffer against...

We tested and validated the German version of a new instrument for measuring "wakefulness," defined as "an expansive, higher-functioning, and stable state of being in which a person's vision of and relationship to the world are transformed, along with their subjective experience, their sense of identity and their conceptual outlook" (Taylor, 2017, p. 22). In order to test the construct validity...

Empathy is a fundamental social ability that allows humans to infer others' emotions and intentions. Empathy is thought to be rooted in bodily sensations coming from the autonomic nervous system. In parallel, the functionality and perceptions coming from the autonomic nervous system could be improved by practicing activities that involve mind-body interactions, such as meditation. Furthermore,...

Absence of consciousness can occur due to a concussion, anesthetization, intoxication, epileptic seizure, or other fainting/syncope episode caused by lack of blood flow to the brain. However, some meditation practitioners also report that it is possible to undergo a total absence of consciousness during meditation, lasting up to 7 days, and that these "cessations" can be consistently induced....

Patients with major depressive disorder (MDD) often exhibit an inadequate treatment response or failure to achieve remission following treatment with antidepressant drugs. Treatment-resistant depression (TRD) is proposed to identify this clinical scenario. Compared to those without TRD, patients with TRD have significantly lower health-related quality of life in mental and physical dimensions,...

Human sleep is a dynamic and complex process comprising sleep stages with REM and NREM sleep characteristics that come in cycles. During sleep, there is a loss of responsiveness or a perceptual loss of conscious awareness with increasing thresholds for wakefulness as sleep progresses. There are brief bursts of wakefulness or Wake After Sleep Onset (WASO) throughout a nocturnal sleep. Conscious...

An altered sensory environment, especially a homogeneous one like a ganzfeld, can induce a wide range of experiences in people immersed in it. The ganzfeld of our current focus is the OVO Whole-Body Perceptual Deprivation chamber (OVO-WBPD). Previous literature has found this specific immersive environment to be capable of softening and dissolving perception of boundaries across time and...

Evidence has suggested that the modulation of N-methyl-d-aspartate receptors (NMDARs) and 5-hydroxytryptamine receptors (5-HTRs) via the psychedelic drugs, such as ketamine and psilocybin, rapidly alters the state of consciousness and the neuroplasticity. The United State Food and Drug Administration approved the indications of esketamine for treatment-resistant depression (TRD) in 2019 and...

Neuroinflammation plays a key role in the pathogenesis of major depressive disorder (MDD), including treatment-resistant depression (TRD). Patients with TRD have higher levels of inflammatory biomarkers compared with responders to antidepressants. Multiple lines of evidence suggest that the gut-microbiota-brain axis via the vagus nerve plays a key role in neuroinflammation. Preclinical and...

Mind-body practices and meditation have been increasingly studied in recent years due to their beneficial effects on cognition, and physical and psychological health. Growing evidence suggests that these practices could be utilized as interventions to impact age-related biological processes, such as cognitive decline, inflammation, and homeostatic dysregulation. Indeed, it has been reported...

Nicotine use and dependence, typically achieved through cigarette smoking, but increasingly through vape products, is the leading cause of preventable death today. Despite a recognition that many current smokers would like to quit, the success rate at doing so is low and indicative of the persistent nature of nicotine dependence and the high urge to relapse. There are currently three main forms...

Rising from its contemplative and spiritual traditions, the science of meditation has seen huge growth over the last 30 years. This chapter reviews the classifications, phenomenology, neural correlates, and mechanisms of meditation. Meditation classification types are still varied and largely subjective. Broader models to describe meditation practice along multidimensional parameters may...

The theory of predictive processing in the comprehensive articulation proposed by Karl Friston is a framework that boasts an impressively wide explanatory power in neurobiology, where processes apparently as diverse as perception, action, attention, and learning unfold, and are coherently orchestrated, according to the single general mandate of free-energy minimization. In the present opinion...

I introduce arguments toward a non-representational reflexivity theory of consciousness-as-such to address one of the key issues in the science of consciousness today: lack of understanding of the nature of consciousness itself. An expanded map of consciousness is outlined, which includes, in addition to the well-known contents of awareness and levels of arousal, the indeterminate substrate and...

All of us consciously experience the world around us through our sensory modalities. Empirical studies on the relationship between attention and awareness have shown that attention does influence perceptual experience or appearance in addition to better performance in perceptual tasks. The practice of meditation also changes perceptual experience in addition to better perceptual performance....

Several studies have demonstrated that meditation naïve subjects can, in just a few weeks, become proficient enough in meditation to show cognitive improvements accompanied with functional and structural changes in the brain. Would long-term exposure to qualitatively different levels of meditative training bring about differences in cognitive processing? Would meditation prior to task...
