Frederick S Barrett, Roland R Griffiths
This chapter begins with a brief review of descriptions and definitions of mystical-type experiences and the historical connection between classic hallucinogens and mystical experiences. The chapter then explores the empirical literature on experiences with classic hallucinogens in which claims about mystical or religious experiences have been made. A psychometrically validated questionnaire is described for the reliable measurement of mystical-type experiences occasioned by classic hallucinogens. Controlled laboratory studies show that under double-blind conditions that provide significant controls for expectancy bias, psilocybin can occasion complete mystical experiences in the majority of people studied...

Beliefs profoundly affect people's lives, but their cognitive and neural pathways are poorly understood. Although previous research has identified the ventromedial prefrontal cortex (vmPFC) as critical to representing religious beliefs, the means by which vmPFC enables religious belief is uncertain. We hypothesized that the vmPFC represents diverse religious beliefs and that a vmPFC lesion would be associated with religious fundamentalism, or the narrowing of religious beliefs. To test this prediction, we assessed religious adherence with a widely-used religious fundamentalism scale in a large sample of 119 patients with penetrating traumatic brain injury (pTBI)...

BACKGROUND: The experience of 'sensed presence'-a feeling or sense that another entity, individual or being is present despite no clear sensory or perceptual evidence-is known to occur in the general population, appears more frequently in religious or spiritual contexts, and seems to be prominent in certain psychiatric or neurological conditions and may reflect specific functions of social cognition or body-image representation systems in the brain. Previous research has relied on ad-hoc measures of the experience and no specific psychometric scale to measure the experience exists to date...

Community health workers (CHWs) can engage elderly persons in advance care planning (ACP) conversations. We report how trained CHWs used Go Wish cards (GW (R) cards) to identify patients' highest priority preferences and evaluated whether engaging in ACP conversations was associated with subsequent health care utilization. A one-year long, pre-post longitudinal design was used to evaluate our educational intervention using mixed-methods. 392 patients (mean of 73.3 years, 82% women, 48% African American, 43% Caucasian) enrolled in the Aging Brain Care (ABC) program and participated in ACP discussions with CHWs...

INTRODUCTION: The brain-derived neurotrophic factor (BDNF) interacts with important genetic Alzheimer's disease (AD) risk factors. Specifically, variants within the SORL1 gene determine BDNF's ability to reduce amyloid β (Aβ) in vitro. We sought to test whether functional BDNF variation interacts with SORL1 genotypes to influence expression and downstream AD-related processes in humans. METHODS: We analyzed postmortem brain RNA sequencing and neuropathological data for 441 subjects from the Religious Orders Study/Memory and Aging Project and molecular and structural neuroimaging data for 1285 subjects from the Alzheimer's Disease Neuroimaging Initiative...

Uterus transplantation is an experimental treatment method with an ambition to become accepted treatment modality for women with absolute uterine factor infertility. The only legal alternative for these women to get parenthood is adoption which is accepted by most world societies and countries. Surrogate pregnancy is connected with many medical, ethical, legal, religious and social controversies in the great part of the world.Donors (in living donation), recipients, partners and also unborn children must be incorporated into the analysis of ethical risks and benefits of uterus transplantation...

Stephen D Brown
This article addresses whether cardiopulmonary resuscitation (CPR) and sustained physiological support should ever be permitted in individuals who are diagnosed as brain dead and who had held previously expressed moral or religious objections to the currently accepted criteria for such a determination. It contrasts how requests for care would normally be treated in cases involving a brain-dead individual with previously expressed wishes to donate and a similarly diagnosed individual with previously expressed beliefs that did not conform to a brain-based conception of death...

BACKGROUND: Three recent lawsuits that address declaration of brain death (BD) garnered significant media attention and threaten to limit physician power to declare BD. METHODS: We discuss these cases and their consequences including: the right to refuse an apnea test, accepted medical standards for declaration of BD, and the irreversibility of BD. RESULTS: These cases warrant discussion because they threaten to: limit physicians' power to determine death; incite families to seek injunctions to continue organ support after BD; and force hospitals to dispense valuable resources to dead patients in lieu of patients with reparable illnesses or injuries...

Group-focused moral foundations (GMFs) - moral values that help protect the group's welfare - sharply divide conservatives from liberals and religiously devout from non-believers. However, there is little evidence about what drives this divide. Moral foundations theory and the model of motivated social cognition both associate group-focused moral foundations with differences in conflict detection and resolution capacity, but in opposing directions. Individual differences in conflict detection and resolution implicate specific neuroanatomical differences...

Anxiety is a psychiatric disorder with unknown neurobiology; however, neurotransmitters like gamma-amino butyric acid, norepinephrine and serotonin (5-HT) play crucial roles in mediating anxiety. Present drug modules pose dependence risk to the patient; hence, there is a great need to develop complementary therapies to fight this disorder. Aromatherapy has also been employed in ancient times for a number of mental disorders. Mahamrituanjay Mantra, Om triambkum yajamahe, sughandhim puushtivardhanam, urvarukmev vandhanaat, mrityu mokshay mamritaat!!!!, the part of veda enlightens that aroma gives rise to good health (sughandhim puushtivardhanam)...

Pehr Granqvist, Frances Nkara
We consider nurture's (including culture's) sculpting influences on the evolved psychological predispositions that are expressed in religious and spiritual (R&S) development. An integrated understanding of R&S development requires a move away from the largely one-sided (nature-or-nurture) and additive (nature + nurture) accounts provided in the extant literature. R&S development has been understood as an expression of evolved cognitive modules (nature) on the one hand, and of socialization and social learning (nurture) on the other, or in similar albeit additive terms (e...

REVIEW
Michiel van Elk, André Aleman
We present the theory of predictive processing as a unifying framework to account for the neurocognitive basis of religion and spirituality. Our model is substantiated by discussing four different brain mechanisms that play a key role in religion and spirituality: temporal brain areas are associated with religious visions and ecstatic experiences; multisensory brain areas and the default mode network are involved in self-transcendent experiences; the Theory of Mind-network is associated with prayer experiences and over attribution of intentionality; top-down mechanisms instantiated in the anterior cingulate cortex and the medial prefrontal cortex could be involved in acquiring and maintaining intuitive supernatural beliefs...

The evolution of funeral practices from the Middle Ages through the Modern era in Europe is generally seen as a process of secularization. The study, through imaging and autopsy, of two mummies, five lead urns containing hearts, and more than six hundred skeletons of nobles and clergymen from a Renaissance convent in Brittany has led us to reject this view. In addition to exceptional embalming, we observed instances in which hearts alone had been extracted, a phenomenon that had never before been described, and brains alone as well, and instances in which each spouse's heart had been placed on the other's coffin...

High-level cognitive and emotional experience arises from brain activity, but the specific brain substrates for religious and spiritual euphoria remain unclear. We demonstrate using functional magnetic resonance imaging scans in 19 devout Mormons that a recognizable feeling central to their devotional practice was reproducibly associated with activation in nucleus accumbens, ventromedial prefrontal cortex, and frontal attentional regions. Nucleus accumbens activation preceded peak spiritual feelings by 1-3 s and was replicated in four separate tasks...

BACKGROUND: The increasing gap between organ supply and demand remains a worldwide problem and can be attributed to several reasons. Because health care workers play an important role in management of brain dead patients, we performed a survey to evaluate the attitude and knowledge of personnel in the intensive care unit (ICU) at Tabriz University of Medical Sciences hospitals toward organ donation. MATERIALS AND METHODS: This cross-sectional study was included personnel from 8 university affiliated ICUs in Northwest of Iran from May to July 2014...

BACKGROUND: Organ transplantation is the optimal treatment for end-stage organ diseases. The demand for organs has exceeded the available supply, which becomes a major obstacle worldwide. Identifying the factors affecting this gap will help in overcoming this obstacle. The purpose of the work was to study the knowledge, attitudes, and beliefs of organ donation and to determine the knowledge of brain death among social media users. METHODS: A cross-sectional study was conducted among social media users living in Saudi Arabia...

BACKGROUND: Since the turn of the last century, the prospect of head transplantation has captured the imagination of scientists and the general public. Recently, head transplant has regained attention in popular media, as neurosurgeons have proposed performing this procedure in 2017. Given the potential impact of such a procedure, we were interested in learning the history of the technical hurdles that need to be overcome, and determine if it is even technically possible to perform such a procedure on humans today...

The prominence of biomedical criteria relying on brain death reduces the impact of metaphysical, anthropological, psychosocial, cultural, religious, and legal aspects disclosing the real value and essence of human life. The aim of this literature review is to discuss metaphysical and biomedical approaches toward death and their complimentary relationship in the determination of death. A critical appraisal of theoretical and scientific evidence and legal documents supported analytical discourse. In the metaphysical discourse of death, two main questions about what human death is and how to determine the fact of death clearly separate the ontological and epistemological aspects of death...
