In recent years, investigations into the psychological experience of time have rapidly accelerated. The experience of time could depend on a ticking internal clock or rely on contextual changes within and between events. Cognitive theories of memory propose that the presence of event boundaries, as defined by unexpected changes, is crucial for the segmentation of sequenced content and...
A widely observed phenomenon across cultures involves the use of rhythmic auditory stimulation in intricate rituals to achieve dissociative mental states. While several physiological mechanisms link repetitive auditory stimuli to nonordinary states of consciousness (NSCs), entrainment-the brainwave synchronization through periodic external stimuli-has received particular attention. However,...
Resilience-the capacity to adapt, recover, and engage dynamically with adversity-has emerged as a central construct for understanding psychological health. Although meditation offers a promising route for cultivating resilience, current scholarship rarely differentiates between the mechanisms of focused attention meditation (FAM) and open monitoring meditation (OMM), thereby obscuring their...
ABSTRACT: The biological origins of meditation in humans remain underexplored, despite extensive scholarship on its cultural history and health effects. We present a theoretical account that traces the origins of meditation to the evolutionarily conserved repertoire of defensive freezing. We propose that this ancient survival response—characterized by motoric immobility, heightened vigilance...
The global mental health crisis has escalated to unprecedented levels, with stress, anxiety, and depression posing major public health concerns. Conventional interventions have shown limited success in addressing these multifaceted issues, prompting researchers to explore alternative solutions. Yoga Nidra (YN), a meditative practice, has gained momentum over the past decade as a potential...
Cannabis use has long been associated with enhanced music experiences, yet scientific research on its effects on auditory perception remains limited. This convergent mixed-methods self-report study investigated how recreational cannabis users experience auditory stimulation and music in particular. A total of 104 participants completed an online questionnaire, 15 of which were selected to...
Abstract Determining the scale of neural representations is a central challenge in neuroscience. While localized representations have traditionally dominated, evidence suggests information is also encoded in distributed, hierarchical networks. Recent research indicates that the hierarchy of causal influences shaping functional patterns serves as a signature of distinct brain states, with...
Humans have long sought to alter their mental states through various cultural practices, with rhythmic sounds emerging as a prominent and enduring method. However, altered states of consciousness induced by rhythmic auditory stimulation have not been comprehensively addressed in academic research, and the associated cognitive and neural underpinnings remain enigmatic. This narrative review...
Mindfulness meditation involves training attention, commonly toward sensory experiences, with nonjudgmental awareness. Theoretical perspectives propose that meditation increases the precision of sensory processing and reduces the generation/elaboration of top-down expectations. Research suggests forward traveling cortical alpha waves may reflect bottom-up inhibition to enhance signal-to-noise...
Over the past two decades, the fields of social and contemplative neurosciences have made significant strides. Initial research utilizing fMRI identified neuronal networks involved in empathy, mentalizing, and compassion, as well as complex interactions among these networks. Subsequent studies shifted to testing the plasticity of these social skills via different types of mindfulness- or...
In this article, we explore the connections between two distinct approaches: experiential learning (EL) and 4E cognition. EL emphasizes the role of concrete experiences as the building blocks of learning, whereas 4E cognition views cognition as arising from the interactions that an individual has with their physical and social environment. Despite their divergent theoretical frameworks,...
Artificial intelligence (AI) and psychedelic medicines are among the most high-profile evolving disruptive innovations within mental healthcare in recent years. Although AI and psychedelics may not have historically shared any common ground, there exists the potential for these subjects to combine in generating innovative mental health treatment approaches. In order to inform our perspective,...
The relationship between integration and awareness is central to contemporary theories and research on consciousness. Here, we investigated whether and how information integration over time, by incorporating the underlying regularities, contributes to our awareness of the dynamic world. Using binocular rivalry, we demonstrated that structured visual streams, constituted by shape, motion, or...
Abstract Music and psychedelics have been intertwined throughout the existence of Homo sapiens , from the early shamanic rituals of the Americas and Africa to the modern use of psychedelic‐assisted therapy for a variety of mental health conditions. Across such settings, music has been highly prized for its ability to guide the psychedelic experience. Here, we examine the interplay between music...
Parnia et al. recently published suggestions for the study of death and experiences recalled in a near‐death context. We have serious reservations about the authors’ statements. In this commentary, we discuss the omissions and knowledge gaps inherent to the authors’ paper, which among others include incorrect neurological claims about brain death and misunderstandings regarding the terminology...
In their recent paper, Parnia and colleagues propose a new label for the near‐death experience (NDE): recalled experience of death. They claimed NDEs are “authentic” only when an objective danger is present and that authentic NDEs have a proven core phenomenology. We consider that these claims are insufficiently supported by empirical data. NDEs appear as a continuum of heterogeneous...
Disruptive innovation is a cornerstone of various disciplines, particularly in the business world, where paradigm-altering approaches are often lauded. As a construct, disruptive psychiatry can be considered to embody such an approach by the pursuit of innovations within the field which test boundaries and shake up the status quo. Given the importance of addressing the current mental health...
An inadvertent consequence of advances in stem cell research, neuroscience, and resuscitation science has been to enable scientific insights regarding what happens to the human brain in relation to death. The scientific exploration of death is in large part possible due to the recognition that brain cells are more resilient to the effects of anoxia than assumed. Hence, brain cells become...
Awe is a self-transcendent emotion that exerts a powerful impact on the self. Through diminishing the ego, awe may help cultivate interconnection, wisdom, meaning, and purpose.
Einstein famously claimed that "the most incomprehensible thing about the universe is that it is comprehensible." This statement suggests that no amount of scientific explanation will suffice to make sense of the bizarre situation of the human mind within the universe. So what are the actual roles of awe and wonder within the framework of contemporary science? How, for instance, do awe and...
The prevalent view in cognitive science is that we construct our perception of reality in real time. But could we be misinterpreting the content of our perceptual experiences? Does what we perceive with our brain and senses reflect the true nature of reality? Might evolution have shaped our perceptions to guide adaptive behavior, without enabling us to see reality as it actually is? In a...
The ratio between frontal resting‐state electroencephalography (EEG) theta and beta frequency power (theta/beta ratio, TBR) is negatively related to cognitive control. It is unknown which psychological processes during resting state account for this. Increased theta and reduced beta power are observed during mind wandering (MW), and MW is related to decreased connectivity in the executive...
There is a growing interest in the effectiveness of mindfulness meditation for sleep disturbed populations. Our study sought to evaluate the effect of mindfulness meditation interventions on sleep quality. To assess for relative efficacy, comparator groups were restricted to specific active controls (such as evidenced-based sleep treatments) and nonspecific active controls (such as...
Where can we turn to find the story of our lives-an existential roadmap that explains where we have come from, why we are here, and where we are headed? Must each of us discover meaning within the context of our individual lives, or are there universal sources of meaning that we can all access? Is there any relationship between living a meaningful life and the quality of our health and...
Integrating information across sensory systems is a critical step toward building a cohesive representation of the environment and one's body, and as illustrated by numerous illusions, scaffolds subjective experience of the world and self. In the last years, classic principles of multisensory integration elucidated in the subcortex have been translated into the language of statistical inference...
