Recent studies of near-death experiences.

Journal of Religion and Health June 1, 1983 J J Heaney

This article consists of a summary of the central points in the work of recent investigators of near-death experiences (NDEs). It considers the work of Moody, Osis, Rawlings, Ring, Sabom, and Grof as well as the criticisms of Noyes and Siegel. The appearance of a common core in the experiences suggests the presence of more than ordinary hallucinations. However, NDEs seem to be not literal...

Psychodynamics of spirit possession among the Inuit.

The Canadian Journal of Psychiatry February 1, 1983 A Seltzer 7 citations

Three cases of spirit possession were studied to determine common underlying psychodynamic factors. The spirits were believed to represent culture bound defense mechanisms, and attempts at problem solving in individuals suffering from unresolved conflicts. These being anomic anxiety, dependency, sexual identity and aggression. The symptoms, therefore, were considered to be attempts at conflict...

Phencyclidine: effects on the fetus and neonate.

Developmental pharmacology and therapeutics 1983 I J Chasnoff, W J Burns, R P Hatcher et al.

As phencyclidine hydrochloride (PCP) has become one of the more frequently abused drugs in the United States, there has been increasing interest in its effect on the fetus and neonate of the pregnant abuser. Two groups of women enrolled in a comprehensive perinatal addiction program were studied: 7 women abused PCP prior to and during pregnancy, and these women were compared to a group of 27...

Effects of chronic administration of antidepressant drugs on central serotonergic receptor mechanisms

Palgrave Macmillan UK eBooks 1983 Sven Ove Ögren, Kjell Fuxé, Odd‐geir Berge et al. 11 citations

The present studies have shown that chronic antidepressant treatment with desipramine (DMI), imipramine (IMI) and zimelidine produced behavioral evidence for sub- and supersensitivity depending on 5-HT agonist dose and types of behavior examined. Thus, chronic treatment with all three drugs reduced head twitches induced by a high dose of the 5-HT agonist 5-methoxy-N,N-dimethyltryptamine...

Effects of apomorphine, clonidine or 5-methoxy-NN-dimethyltryptamine on approach and escape components of lateral hypothalamic and mesencephalic central gray stimulation in two inbred strains of mice.

Pharmacology, Biochemistry, and Behavior 1983 P Cazala, A M Garrigues 11 citations

The effects of intraperitoneal injections of increasing doses of apomorphine, clonidine or 5-methoxy-NN-dimethyltryptamine (5-m-DMT) on approach and escape reactions induced by lateral hypothalamic (LH) or mesencephalic central gray (CG) stimulation were compared in BALB/c and DBA/2 mice. Apomorphine increased both the approach latency for LH stimulation and the escape latency for CG...

Behavioral effects of 5-methoxy-N,N-dimethyltryptamine and dose-dependent antagonism by BC-105.

Psychopharmacology 1983 R Young, John A. Rosecrans, Richard A Glennon 25 citations

The discriminative effects of 5-methoxy-N,N-dimethyltryptamine (5-OMeDMT) were studied in rats trained to discriminate 1.5 mg/kg or 3.0 mg/kg 5-OMeDMT from saline. A series of antagonist and generalization tests revealed that (1) antagonism of the 5-OMeDMT stimulus response by the presumed serotonin antagonist BC-105 depended on the dose of 5-OMeDMT, (2) the 5-OMeDMT stimulus generalized to...

Inhibition of prolactin release by stimulation of presynaptic serotonin autoreceptors.

Life Sciences December 6, 1982 J A Clemens, M E Roush 8 citations

The effects of 5-methoxy-N,N-dimethyltryptamine (5-MeODMT), a serotonin agonist with a preferential action on presynaptic autoreceptors, on prolactin release in male rats was determined. Basal serum prolactin levels were not altered after administration of 1.0, 2.0, 5.0, 10.0 or 20.0 mg/kg of 5-MeODMT. Pretreatment with 5-MeODMT reduced prolactin release by agents that depend on serotonergic...

Depersonalization in the light of Brentano's phenomenology

British Journal of Medical Psychology December 1, 1982 F. Kräupl Taylor

The symptoms of depersonalization are examined in the light of the phenomenological views evolved by Franz Brentano. He had come to the conclusion that our conscious experiences are primarily directed towards objects (contents) that are ‘phenomenal’ or ‘intentional’ in the sense that they do not necessarily have counterparts in the external world. In experiencing such an object, a person...

Medullary serotonergic neurons are insensitive to 5-MeoDMT and LSD.

European Journal of Pharmacology July 30, 1982 J Heym, G F Steinfels, Barry L. Jacobs 21 citations

A comparison was made of the effects of 5-MeoDMT or LSD on serotonergic unit activity in the dorsal raphe nucleus (DRN) and nucleus raphe pallidus (NRP) of freely moving cats. NRP neurons were substantially less responsive than DRN neurons to both drugs. NRP neurons were unresponsive to behaviorally effective low doses of these drugs whereas the activity of DRN neurons was strongly depressed....

Are psychological studies of religion on the right track?

Religion July 1, 1982 Richard A. Hutch 9 citations

Researchers in psychology of religion in America and Britain have inherited the theoretical and research traditions established by W. James, S. Freud and J. Dittes. New nomothetic or theoretical frameworks have been called for in order to organize a plethora of idiographic data. A response to the call has been slow, but Paul Pruyser designated at least six areas in which the development of...
