This paper is a theoretical presentation of religious experience as thefundamental element of religion and in the study of religion(s). It states that religion or religiousness is a characteristic of human beings who have an attraction to an objective reality outside of humans but considered Ultimate, Divine, and Sacred in essence and action. Humans generally consider themselves dependent on...
Claims from those having near-death experiences (NDEs), as well as those sympathetic to such claims, challenge the prevailing assumption that consciousness is dependent on a functioning brain. Extant theories, both neurobiological and psychosocial, that attempt to explain NDEs are examined and found unable to adequately account for the full range of NDE reports, especially electromagnetic...
Ecstasy (from the Greek, ekstasis: distraction; derangement; astonishment) is defined by dictionaries as (1) an emotional state so intense that one is carried beyond rational thought or self-control; (2) rapture associated with mystical experience. In this essay, we take the position that “addiction” is a social construct, a term that reflects a societal convention as much or more so that its...
The posterior cingulate cortex (PCC) is a central part of the default mode network (DMN) and part of the structural core of the brain. Although the PCC often shows consistent deactivation when attention is focused on external events, anatomical studies show that the region is not homogeneous, and electrophysiological recordings in nonhuman primates suggest that it is directly involved in some...
A novel series of mGluR2 positive allosteric modulators (PAMs), 1-[(1-methyl-1H-imidazol-2-yl)methyl]-4-phenylpiperidines, is herein disclosed. Structure-activity relationship studies led to potent, selective mGluR2 PAMs with excellent pharmacokinetic profiles. A representative lead compound (+)-17e demonstrated dose-dependent inhibition of methamphetamine-induced hyperactivity and...
Neurotoxicity of the amphetamine analogs methamphetamine (METH) and 3,4-methylenedioxyamphetamine (MDA) (the active metabolite of ecstasy) may involve their prostaglandin H synthase (PHS)-dependent bioactivation to free radical intermediates that generate reactive oxygen species and oxidatively damage cellular macromolecules. We used Chinese hamster ovary-K1 (CHO-K1) cell lines either...
Videogame players commonly report reaching deeply "immersive" states of consciousness, in some cases growing to feel like they actually are their characters and really in the game, with such fantastic characters and places potentially only loosely connected to offline selves and realities. In the current investigation, we use interview and survey data to examine the effects of such...
Cannabinoids have long been shown to have a range of potential therapeutic effects, including antiemetic actions, analgesia, and anxiolysis. However, psychomimetic and memory disruptive side effects, as well as the potential for abuse and dependence, have restricted their clinical development. Endogenous cannabinoids (i.e., endocannabinoids; eCBs), such as anandamide (AEA) and...
Marijuana (cannabis) is the most widely used illicit substance globally, and cannabis use is associated with a range of adverse consequences. Currently, no medications have been proven to be effective for the treatment of cannabis addiction. The goals of this study were to examine the safety and efficacy of a potential treatment medication, modafinil, in combination with oral...
Background: Age at onset of psychosis (AAO) may be younger in patients with cannabis use disorders (CUD) compared to those without CUD (NCUD). Most previous studies did not control for potential confounders, did not report effect sizes and included mostly adult patients from non-representative samples. Methods: Controlling for relevant confounders, differences in AAO between patients with and...
