The present report discusses brain visual experiences in conditions of low degree of openness of the brain toward the environment, for example, while dreaming, during meditation, or in non-ordinary brain activity states such as under the effects of psychoactive substances, in the state of coma, or in other states of reduced sensory perception, among others. In the present report, for brevity,...
Abstract Psilocybin is the active component of magic mushrooms and is well known for its psychoactive properties. Different questionnaires have been developed to systematically quantify altered states of consciousness induced by psychoactive drugs. The aim of this study was to obtain the dose-response relationships of the subjective experiences induced by psilocybin in healthy study...
Abstract There has recently been a resurgence of philosophical and scientific interest in the foundations of self-consciousness, with particular focus on its altered, anomalous forms. This paper looks at the altered forms of self-awareness in Depersonalization Disorder (DPD), a condition in which people feel detached from their self, their body and the world (Derealisation). Building upon the...
This story is about the twentieth-century ethnobotanist, Richard Evans Schultes (1915-2001), and his research on hallucinogenic plants. Ethnobotany can contribute directly to science and technology studies in that the discipline makes cultural ways of knowing its scientific subject. Ethnobotanists must learn about plants through people, and are not able to conceal their interactions with...
Abstract 1‐Propanoyl‐lysergic acid diethylamide (1P‐LSD) appeared as a non‐controlled alternative to LSD a few years ago. Although evidence is beginning to emerge from in vitro and animal studies that 1P‐LSD might serve as a prodrug for LSD, an equivalent evaluation in humans is unavailable. Controlled oral and intravenous self‐administrations of 100 μg 1P‐LSD hemitartrate are reported in two...
Hypnosis is a modified state of consciousness widely used to decrease pain perception in research protocols and clinical practice. In recent decades, hypnosis has been increasingly proposed to patients to re-engage their resources and capacities to modulate pain and emotional distress and to improve their treatment and recovery of well-being. Neuroimaging research helps clinicians to understand...
Physical pain represents a common feature of Bondage and Discipline/Dominance and Submission/Sadism and Machochism (BDSM) activity. This article explores the literature accounting for how painful stimuli may be experienced as pleasurable among practitioners of BDSM, and contrasting this with how it is experienced as painful among non-BDSM individuals. We reviewed the available literature on...
Abstract In the 1960s a shift occured in how shamanism was represented in Soviet anti-religious journals, in which shamanism was transformed from an ethnographically documented cultural practice peculiar to Siberian indigenous populations, into an – albeit ‘primitive’ – form of a universal human capacity for altered states of consciousness and a precursor of various forms of mysticism. The...
In this article, I present the concept of “birthing consciousness,” a psychophysical altered state of women that can occur during natural and undisturbed birth. I demonstrate that this altered state of consciousness (ASC) has phenomenological and cognitive features of hypofrontality; thus, birthing consciousness probably shares a similar brain mechanism to that postulated by the...
This paper explores Aryeh Kaplan’s approach to Kabbalah, specifically the topics of mystical consciousness, meditation, God, and prophecy as presented in his Sefer Yetzirah commentary. For him, Kabbalah was operational as a path of higher consciousness; therefore, he gives scant attention to theosophic Kabbalah. Kaplan’s approach was to recreate a Kabbalah of consciousness with what he calls...
