This article examines the neurobiological basis of the healing power attributed to shamanic practices in the Andes and Brazil in light of the pharmacology of neurotransmitters and the new technological explorations of brain functioning. The psychotropic plants used in shamanic psychiatric cures interfere selectively with the intrinsic neuromediators of the brain. Mainly they may alter: (1) the neuroendocrine functioning through the adrenergic system by controlling stressful conditions, (2) the dopaminergic system in incentive learning and emotions incorporation, (3) the serotoninergic system (...) in modulating behaviors, and mood, and (4) basic functions implied in anxiety or depression. PET scans and functional magnetic resonance imaging studies of hypnotic trance and altered states of consciousness may provide a useful model for the neurophysiological phenomena of shamanic drum-and-dance trance. The reorganization of cortical areas and the direct interconnections between the prefrontal cortex and the dopaminergic reward centers in the limbic system are of particular significance for human social judgment and symbolic processing. Those centers—including the hypothalamus and the amygdala (associated with psychosomatic equilibrium, memory, and emotion) are enhanced. This arousal may be amplified in order to induce a cathartic crisis—the shamanic trance. It is suggested that through this holistic approach the shaman empirically interferes in neurobiological dysfunctions. (shrink)

There has been a renewed interest in psychology and anthropology in the idea of altered states of consciousness. This paper begins by examining the meaning of this term and the extent to which such experiences are reported globally. The topic of shamanism is then discussed, first with respect to its social functions, and then to what is known about its psychological aspects (which is little). Far more is known about altered states of consciousness (ASCs) as they are expressed in meditation, (...) trance and possession, and channeling, and a number of studies are reviewed, both of individuals and of groups, which illustrate the full extent of ASCs. The following section then goes more deeply into the stimulus situations that are associated with ASCs. This brings the discussion into drugs, attempts at altering the sensorium (music and imagery in particular) and recent technological innovations, peculiar to our time, which deliberately alter our usual state of awareness through feedback principles. In the final section, what is known about the physiology of ASCs is reviewed and also the extent to which these phenomena, including shamanism, are regarded as pathological. As a great number of people across the world utilize the healing aspects of trance, possession and shamanic practices, this aspect is discussed, and lastly the adaptive functions of ASCs are considered, with their context in the history of psychology.

This article reevaluates the mystical techniques and experiences peculiar to Abraham Abulafia’s Kabbalah and attempts to offer an alternative approach to their dominant understanding, which largely depends on Moshe Idel’s work. Current scholars of Jewish mysticism have a habit of highlighting the “unique character” of Abulafia’s mystical practices while asserting that they cannot be compared with the induction techniques and the psychophysical phenomena typical of hypnosis. While generally agreeing with the scholars discussed that the hyperactivation of the mind found in (...) Abulafian Kabbalah contrasts sharply with the mental relaxation attained through the mystical practices of other religious traditions, the present study takes issue with the current view of Abulafian Kabbalah’s relation to hypnotic procedures, processes, and states. This work addresses the issues present with the current view and offers a more inclusive model for interpreting Abulafia’s Kabbalah, drawing from psychiatrist Roland Fischer. (shrink)

This paper examines patient preparation and perceived outcomes of treatment given by the popular Brazilian Spiritist healer, Dr. Fritz. The data utilized include the results of 40 personal interviews of Spiritist patients conducted by the author during a seven month stay in Fortaleza, Brazil, plus subsequent follow-up information. The study finds that a clear majority of the patients expressed belief that their treatments were successful. Certain trends in the types of illnesses for which the Spiritist surgeries appear to have greater (...) success are also suggested. The author stresses the strength, sophistication, and appropriateness of the healing system in its cultural context and the extensive use of powerful symbolism in both the ritual preparations and the surgeries themselves as key factors in the healing system's success. The findings likewise have clear theoretical implications for the current literature on symbolic healing systems in general. (shrink)
