This book examines shamanism from evolutionary and biological perspectives to identify the origins of shamanic healing in rituals that enhance individual and group function. What does the brain do during "soul journeys"? How do shamans alter consciousness and why is this important for healing? Are shamans different from other kinds of healers? Is there a connection between the rituals performed by chimpanzees and traditional shamanistic practices? All of these questions—and many more—are answered in Shamanism, Second Edition: A Biopsychosocial Paradigm of Consciousness and Healing. This text contains crosscultural examinations of the nature of shamanism, biological perspectives on alterations of consciousness, mechanisms of shamanistic healing, as well as the evolutionary origins of shamanism. It presents the shamanic paradigm within a biopsychosocial framework for explaining successful human evolution through group rituals. In the final chapter,"the author compares shamanistic rituals with chimpanzee displays to identify homologies that point to the ritual dynamics of our ancient hominid ancestors.

This book takes what is often referred to as the "supernatural" to be normal natural phenomena that are closely linked to the neurobiology of the human species. Reflecting the neurocultural and biocultural perspective, the chapters cover phenomena such as out-of-body experiences, ghosts, and experiences of spirit entities. The contributors consider the "supernatural" as emerging from innate neurobiological structures and functions, and reflecting known neurobiological processes that explain their universality and persistence.

Researchers, program administrators, and practicing clinicians explain the most recent developments in using psychedelic substances to treat psychological, physiological, and social problems. More than a decade ago, the U.S. government lifted its ban on all testing of psychedelic substances. Winkelman and Sessa now provide updated scientific research and applications of these substances, now moving into approved categories of medicine. The text is an up-to-date assessment of the latest advances in the field of psychedelic medicine, covering the use of LSD, psilocybin, MDMA, ayahuasca, and other substances to augment psychotherapies for a range of disorders. It discusses medical and psychiatric concerns, clinical efficacy and safety, ethical considerations, and neuroscience findings regarding the psychedelic compounds. Topics covered include an overview of psychiatric applications of psychedelics; treatments for addictions and depressive disorders; effects of psychedelics on inflammation and neuroplasticity; evidence for clinical applications of DMT, ayahuasca, and cannabidiol; psychedelic treatment of sociopathic disorders; microdosing psychedelics; training psychedelic therapists; and community-based harm reduction approaches to managing psychedelic crises. Describes the history of psychedelics as therapeutic treatments and the current renaissance of interest in them Details the training of therapists in applications of psychedelics, and medical theory for the effectiveness of these substances Addresses issues of clinical efficacy and safety as well as ethical considerations Comprises the latest neuroscience research related to the effects of the psychedelic compounds Provides timely information for clinicians, researchers, and advanced students of psychology, medicine, and public health, from leading clinicians, researchers, and administrators in the field

This authoritative, multidisciplinary overview of altered states of consciousness (ASC) shows how their study is necessary to gain a fundamental understanding of human culture, history, and biology. Altered consciousness is one of humanity's most mystical and life-altering aspects. These remarkable changes in mental state have understandably been a topic of general interest and scientific inquiry across time. Beyond simply satisfying our curiosity, however, studies focused upon altered consciousness can also bring valuable insights into our experience, biology, and culture. This unprecedented two-volume set will intrigue anyone interested in psychology, biology and neurology, science, history, arts and the humanities, and literature on consciousness, from general readers to scholars and researchers. An impressive collection of international contributors address altered states of consciousness from the perspectives of history, evolution, psychology, culture, literature, human biology, contemporary science, and society, seeking to illuminate the causes, effects, and meanings of altered consciousness. The first volume provides an introduction and centers on the importance of altered states in history, culture, and the humanities, while the second volume presents biological and psychological perspectives on altered consciousness and examines their potential for healing and pathology.
