Empirical findings in the Cognitive Sciences on the relationship between feeling states and subjective time have led to the assumption that time perception entails emotional and interoceptive states. The perception of time would thereafter be embodied; the bodily self, the continuous input from the body is the functional anchor of phenomenal experience and the mental self. Subjective time...
The state space of a conventional Hopfield network typically exhibits many different attractors of which only a small subset satisfies constraints between neurons in a globally optimal fashion. It has recently been demonstrated that combining Hebbian learning with occasional alterations of normal neural states avoids this problem by means of self-organized enlargement of the best basins of...
Being ‘in flow’ or ‘in the zone’ is defined as an extremely focused state of consciousness which occurs during intense engagement in an activity. In general, flow has been linked to peak performances (high achievement) and feelings of intense pleasure and happiness. However, empirical research on flow in music performance is scarce, although it may offer novel insights into the question of why...
Salvinorin A is a kappa opioid agonist and the principal psychoactive constituent of the plant Salvia divinorum, which has increased in popularity as a recreational drug over the past decade. Few human studies have examined salvinorin A. This double-blind, placebo-controlled study evaluated the dose-related effects of inhaled salvinorin A in individuals with histories of hallucinogen use. Eight...
Although reports of dextromethorphan (DXM) abuse have increased recently, few studies have examined the effects of high doses of DXM. This study in humans evaluated the effects of supratherapeutic doses of DXM and triazolam. Single, acute oral doses of DXM (100, 200, 300, 400, 500, 600, 700, and 800 mg/70 kg), triazolam (0.25 and 0.5 mg/70 kg), and placebo were administered to 12 healthy...
Salvia divinorum is a hallucinogenic plant with ethnopharmacological and recreational uses. It differs from classic serotonergic hallucinogens such as LSD and psilocin in both phenomenology and potent agonist activity of the active component salvinorin A at κ-opioid receptors. Awareness of S. divinorum has grown recently, with both an increase in its public representation and concern over its...
The paucity of formal scientific research into the therapeutic potential of nonordinary states of consciousness is addressed in this article. A literature review examines the historical development of this field, providing the context that shaped the thinking of its major contributors. Key terms are then defined, and a theory for how nonordinary states of consciousness can affect one's...
Near-death experience exhibits many attributes of mystical awareness. Assessing the mystical quality of psychedelic experience, Walter Pahnke identified a nine-category typology of mystical experience. It is used here to illustrate the mystical nature of near-death experience. The typology also describes the self-transformation which follows the mystical state of consciousness....
This essay offers a reassessment of Teresa's severe seizures which were such a characteristic feature of her mysticism. The diagnosis of hysteria is no longer viable, at the very least given its abandonment by clinicians. An alternative analysis is developed by phenomenologically comparing Teresa's seizures to parallel experiences of subjects in LSD-assisted psychotherapy. Using Stanislav...
This Spring I received a long distance telephone call from Dean Samuel Miller, who invited me to give this year's Ingersoll Lecture on human immortality. Three days later, Dean Miller was dead. When I heard the sad news, I, as many of you no doubt, began to think about the way he had influenced me, especially during my theological training here at Harvard Divinity School. One of my most vivid...
