This paper presents an empirical model for interpreting evidence of ritual practices and alterations of consciousness, derived from a cross-cultural study. The four main types of religious practitioners—the healer complex (shaman, shaman/healer and healer), the medium, the priest and the sorcerer/witch—are described in terms of their characteristic roles, experience of altered states of...

The effect of low doses (<=20 μg) of LSD on working memory, in the absence of altered states of consciousness, remain largely unexplored. Given its possible effects on serotonin 5-HT2A receptors and dopaminergic signalling, it could be hypothesised that LSD microdoses modulate working memory recall. Moreover, in line with computational models, LSD microdoses could exert antagonistic effects on...
Palliative Care Perspectives December 1, 2021 James L. Hallenbeck
This chapter discusses the spiritual and psychosocial aspects of care using a narrative approach. It suggests that far more suffering in patients with advanced illness results from psychic rather than from physical distress, assuming physical symptoms are reasonably palliated. Categories of psychic distress described include depression, anxiety, and delirium. A discussion of anticipatory and...

Continuous switching between internal and external modes in the brain appears important for generating models of the self and the world. However, how the brain transitions between these two modes remains unknown. We propose that a large synchronization fluctuation of brain networks, emerging only near criticality (i.e., a balanced state between order and disorder), spontaneously creates...

Can the use of psychedelic drugs induce lasting changes in metaphysical beliefs? While it is popularly believed that they can, this question has never been formally tested. Here we exploited a large sample derived from prospective online surveying to determine whether and how beliefs concerning the nature of reality, consciousness, and free-will, change after psychedelic use. Results revealed...

In 2014, engineers and entrepreneurs began meeting up in San Francisco to explore how virtual reality and lucid dreaming headsets using electroencephalography and other kinds of biofeedback could stimulate altered mental states. They called these practices “consciousness hacking” and referred to research, financing, and design efforts around these wearables as a movement. Unlike Quantified Self...

Sensitivity to paranormal phenomena can be a source of emotional, mental and psychospiritual stress for individuals demonstrating verified mediumistic abilities, yet integrating these anomalous experiences in a healthy, affirming manner can reduce distress and potentially deflect ego dystonic diagnoses of pathology. Because mediums can relay information which appear to be otherworldly from...

Psychedelics are drugs capable of eliciting profound alterations in the subjective experience of the users, sometimes with long-lasting consequences. Because of this, psychedelic research tends to focus on human subjects, given their capacity to construct detailed narratives about the contents of their consciousness experiences. In spite of its relevance, the interaction between serotonergic...

However, research on how psychedelics interact with other psychoactive substances remains scarce. OBJECTIVES: The current study aimed to explore the subjective effects of psychedelics when used alongside cannabis. METHODS: Participants (n = 321) completed a set of online surveys...
