Ecstasy in the Classroom
Can ecstatic experiences be studied with the academic instruments of rational investigation? What kinds of religious illumination are experienced by academically minded people? And what is the specific nature of the knowledge of God that university theologians of the Middle Ages enjoyed compared with other modes of knowing God, such as rapture, prophecy, the beatific vision, or simple faith? Ecstasy in the Classroom explores the interface between academic theology and ecstatic experience in the first half of the thirteenth century, formative years in the history of the University of Paris, medieval Europe’s “fountain of knowledge.” It considers little-known texts by William of Auxerre, Philip the Chancellor, William of Auvergne, Alexander of Hales, and other theologians of this community, thus creating a group portrait of a scholarly discourse. It seeks to do three things. The first is to map and analyze the scholastic discourse about rapture and other modes of cognition in the first half of the thirteenth century. The second is to explicate the perception of the self that these modes imply: the possibility of transformation and the complex structure of the soul and its habits. The third is to read these discussions as a window on the predicaments of a newborn community of medieval professionals and thereby elucidate foundational tensions in the emergent academic culture and its social and cultural context. Juxtaposing scholastic questions with scenes of contemporary courtly romances and reading Aristotle’s Analytics alongside hagiographical anecdotes, Ecstasy in the Classroom challenges the often rigid historiographical boundaries between scholastic thought and its institutional and cultural context.

Deleuze, altered states and film
Deleuze, Altered States and Film offers a typology of altered states, defining dream, hallucination, memory, trance and ecstasy in their cinematic expression. The book presents altered states films as significant neurological, psychological and philosophical experiences. Chapters engage with films that simultaneously present and induce altered consciousness. They consider dream states and the popularisation of alterity in drugs films. The altered bodies of erotic arousal and trance states are explored, using haptics and synaesthesia. Cinematic distortions of space and time as well as new digital and fractal directions are opened up.

The Esoteric Symbolism of Shamanic Trance and Altered States Phenomena
Bringing together extensive research on psychology, psychophysiology and phenomenology of the shamanic trance and altered states of consciousness, this book represents a cross-cultural approach to the study of shamanism. It discusses Buryat shamanism in Siberia in comparison with Buddhist and Hindu Yogic techniques, as well as other esoteric traditions. The phenomenon of the shamanic trance is here investigated from the esoteric point of view as a form of mystical or religious experience. The book explores the inner feelings and psychic states of the shaman during the trance, describing the inner psychic processes and referring to the systems of chakras and subtle channels in shamanism and classical Buddhist and Hindu yoga, as well as other cultural traditions. In addition to its adoption of psychoanalytic and transpersonal approaches, it also uses phenomenological methods in its investigation, representing works from scholars in Oriental studies, as they provide deeper insight into the research of shamanism and mystical experiences.

Alterations of consciousness and mystical-type experiences after acute LSD in humans
Rationale
Lysergic acid diethylamide (LSD) is used recreationally and in clinical research. Acute mystical-type experiences that are acutely induced by hallucinogens are thought to contribute to their potential therapeutic effects. However, no data have been reported on LSD-induced mystical experiences and their relationship to alterations of consciousness. Additionally, LSD dose- and concentration-response functions with regard to alterations of consciousness are lacking.
Methods
We conducted two placebo-controlled, double-blind, cross-over studies using oral administration of 100 and 200 μg LSD in 24 and 16 subjects, respectively. Acute effects of LSD were assessed using the 5 Dimensions of Altered States of Consciousness (5D-ASC) scale after both doses and the Mystical Experience Questionnaire (MEQ) after 200 μg.
Results
On the MEQ, 200 μg LSD induced mystical experiences that were comparable to those in patients who underwent LSD-assisted psychotherapy but were fewer than those reported for psilocybin in healthy subjects or patients. On the 5D-ASC scale, LSD produced higher ratings of blissful state, insightfulness, and changed meaning of percepts after 200 μg compared with 100 μg. Plasma levels of LSD were not positively correlated with its effects, with the exception of ego dissolution at 100 μg.
Conclusions
Mystical-type experiences were infrequent after LSD, possibly because of the set and setting used in the present study. LSD may produce greater or different alterations of consciousness at 200 μg (i.e., a dose that is currently used in psychotherapy in Switzerland) compared with 100 μg (i.e., a dose used in imaging studies). Ego dissolution may reflect plasma levels of LSD, whereas more robustly induced effects of LSD may not result in such associations.

Do Highly Sensitive Persons Experience More Nonordinary States of Consciousness During Sensory Isolation?
Our aim was to investigate whether or not highly sensitive persons experienced more nonordinary/altered states of consciousness (ASC) during 45 minutes of sensory isolation in a flotation tank, than did less sensitive persons. Psychology students (N = 57) were allocated to 1
of 2 groups (high and low levels of sensitivity) depending on their score on the Highly Sensitive Person Scale. Prior to the flotation session participants completed questionnaires to assess their degree of depression, anxiety, optimism, absorption, and how often they had experienced a mystical
state. After the flotation session we assessed degree of ASC. The main finding was that the highly sensitive individuals experienced significantly more ASC during flotation than did the individuals in the low sensitivity group. Further, the highly sensitive participants had significantly more
absorption and anxiety, and had experienced mystical states more frequently prior to flotation, in comparison to individuals with low-level sensitivity.

A single inhalation of vapor from dried toad secretion containing 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) in a naturalistic setting is related to sustained enhancement of satisfaction with life, mindfulness-related capacities, and a decrement of psychopathological symptoms
Background5-methoxy-N,N-dimethyltryptamine (hereinafter referred to as 5-MeO-DMT) is a psychedelic substance found in the secretion from the parotoid glands of the Bufo alvarius toad. Inhalation of vapor from toad secretion containing 5-MeO-DMT has become popular in naturalistic settings as a treatment of mental health problems or as a means for spiritual exploration. However, knowledge of the effects of 5-MeO-DMT in humans is limited.AimsThe first objective of this study was to assess sub-acute and long-term effects of inhaling vapor from dried toad secretion containing 5-MeO-DMT on affect and cognition. The second objective was to assess whether any changes were associated with the psychedelic experience.MethodsAssessments at baseline, within 24 h and 4 weeks following intake, were made in 42 individuals who inhaled vapor from dried toad secretion at several European locations.ResultsRelative to baseline, ratings of satisfaction with life and convergent thinking significantly increased right after intake and were maintained at follow-up 4 weeks later. Ratings of mindfulness also increased over time and reached statistical significance at 4 weeks. Ratings of depression, anxiety, and stress decreased after the session, and reached significance at 4 weeks. Participants that experienced high levels of ego dissolution or oceanic boundlessness during the session displayed higher ratings of satisfaction with life and lower ratings of depression and stress.ConclusionA single inhalation of vapor from dried toad secretion containing 5-MeO-DMT produces sub-acute and long-term changes in affect and cognition in volunteers. These results warrant exploratory research into therapeutic applications of 5-MeO-DMT.

Phenomenological assessment of psychedelics induced experiences: Translation and validation of the German Challenging Experience Questionnaire
Several measures have been designed to assess subjective experiences induced by psychedelic substances or other mind-altering drugs as well as non-pharmacological methods. Recently, two self-report questionnaires have been introduced to measure acute adverse effects following psilocybin ingestion and the phenomenon of ego-dissolution associated with the use of psychedelics, respectively. The 26-item Challenging Experience Questionnaire assesses multiple facets of psilocybin induced experiences on seven subscales, whereas the 8-item Ego-Dissolution Inventory consists of a unidimensional scale. In the present study, these questionnaires were translated into German and their psychometric properties then evaluated in an online survey on psychedelics induced experiences. Confirmatory factor analysis suggested an acceptable fit of the 7-factor structure of the German Challenging Experience Questionnaire with overall good internal consistency for all subscales. The factor structure did not differ based on gender or prior struggle with a psychiatric disorder, furthering the evidence of internal validity. Correlations with the State-Trait-Anxiety Inventory and the Altered States of Consciousness Rating Scale demonstrated convergent validity. Confirmatory factor analysis did not support the hypothesized single-factor structure of the German Ego-Dissolution Inventory and exploratory factor analysis suggested an alternative factor structure, where only five items loaded onto a common factor that was interpreted as ego-dissolution. Internal consistency of this 5-item measure was high and correlation with selected items of the Mystical Experience Questionnaire and Altered States of Consciousness Rating Scale supported convergent validity. Translation and validation of these questionnaires contribute to the advancement of common standards in the psychological and neuroscientific study of altered states of consciousness.
