This study explores the use of immersive Virtual Reality (VR) cave environments to investigate hypotheses concerning altered states of consciousness, creativity, and flexible thinking in archaeological contexts. Building on the premise that ancient humans used caves as sites for rituals involving altered consciousness, we recreated a virtual cave environment to simulate these experiences and...
Abstract The relationship between the default mode network (DMN) and task-positive networks, such as the frontoparietal control network (FPCN), is a prominent feature of functional connectivity (FC) in the human brain. This relationship is primarily anticorrelated at rest in healthy brains and is disrupted in altered states of consciousness. Although the DMN and FPCN seem to perform distinct...

Abstract High ventilation breathwork is a breathing practice that involves deep, accelerated breathing over a prolonged duration (> 15 minutes). This basic practice underpins a wide range of traditions, from Pranayama to Holotropic and Conscious-Connected breathwork. Anecdotal reports suggest that it can benefit physical and mental health, often by evoking altered states of consciousness....
Abstract Progress in the scientific study of altered states of consciousness (ASCs) has been hindered by methodological and conceptual problems. At a methodological level there is a lack of agreement on the scales and instruments used to measure and categorize ASCs. At a conceptual level, existing typologies (such as trigger-based, phenomenology-based, attribution-based, neurobiological, and...
This systematic review aims to elucidate the nexus between ketamine's psychoactive properties and its efficacy in treating a broad spectrum of psychiatric disorders. We searched three databases and used citation tracking to include 29 studies. Predominantly, mood disorders, including bipolar disorder (BD) and major depressive disorder (MDD) (MDD + BD: + n = 25 studies), a large part of them...
The mind-body relationship has long been a subject of inquiry from both philosophical and scientific perspectives. Ancient Greek philosophers such as Pythagoras and Plato posited dualistic models, where the mind and body are distinct substances. In contrast, modern approaches in Mind-Body Medicine (MBM) offer integrative models that emphasize the interconnectedness of mental and physical states...
The development of digital technologies leads to new types of relationships between the digital world and human consciousness, increasingly inducing or influencing specific types of experiences, such as dreams, transcendental experiences, or derealisation. The varied devices used to induce these experiences, from brain-stimulating magnets to biofeedback-based VR headsets, constitute a new class...
The aim of this paper is to show how a monastic environment can be regarded as providing shelter for individuals with autism spectrum condition in the Middle Ages. By drawing on the recent literature in the history of medicine that traces the signs and symptoms of ASC in Hildegard of Bingen, a Benedictine abbess from the twelfth century, we will turn to her invented language Lingua Ignota as a...
How is language related to consciousness? Language functions to categorise perceptual experiences (e.g., labelling interoceptive states as 'happy') and higher-level constructs (e.g., using 'I' to represent the narrative self). Psychedelic use and meditation might be described as altered states that impair or intentionally modify the capacity for linguistic categorisation. For example,...
In recent years, there has been a renewed interest in the conceptual and empirical study of altered states of consciousness (ASCs) induced pharmacologically or otherwise, driven by their potential clinical applications. To draw attention to the rich history of research in this domain, we review prominent classification schemes that have been proposed to introduce systematicity in the scientific...
