Altered States of Consciousness, State‐dependent Learning and Patient Education

Scandinavian Journal of Caring Sciences September 12, 1987 Torill Christine Lindstrøm

ABSTRACT. Evidence as to the existence of various altered states of consciousness are referred to from various fields of research. The effect of mental and physiological states on learning and retrieving is also documented. This evidence is combined to shed a new light on problems in patient education. Problems here are usually explained as stemming from various intellectual or motivational...

Phencyclidine-induced head-weaving observed in mice after ritanserin treatment.

European Journal of Pharmacology July 9, 1987 Toshitaka Nabeshima, K Ishikawa, K Yamaguchi et al. 17 citations

Ritanserin (0.125, 0.25, 0.5, 1.0 and 2.0 mg/kg s.c.), a selective serotonin (5-HT2) receptor antagonist, produced a dose-dependent inhibition of the head-twitch response induced in mice by phencyclidine (PCP) and 5-methoxy-N,N-dimethyltryptamine (5-MeODMT). In contrast, ritanserin, dose dependently increased PCP- and 5-MeODMT-induced head-weaving. There was a significant inverse relationship...

Dose-dependent effects of phencyclidine on hippocampal CA1 neurons.

Canadian journal of physiology and pharmacology May 1987 P W Kujtan, P L Carlen

The dose-dependent effects of phencyclidine were examined in guinea pig hippocampal slices using intracellular and extracellular recordings. Orthodromically evoked population potentials from the CA1 cell body layer were enhanced by low doses (0.2-0.4 microM) and depressed by high doses (0.01-10 mM). Medium doses of the drug (2.0-10.0 microM) showed little effect. Intracellular recordings from...

Carlos Castaneda

Journal of Humanistic Psychology April 1, 1987 Walter A. Shelburne 1 citation

The significance of Castaneda's account of reported experiences with Don Juan Matus is explored for transpersonal psychology. It is argued that the Don Juan chronicle cannot be a literally true account. Yet, I contend that Castaneda tries to discuss seriolus issues allegorically. On the content level, the message is said to consist of several of Don Juan's teachings. I argue that the manner of...

Biochemical and histological evidence that methylenedioxymethylamphetamine (MDMA) is toxic to neurons in the rat brain.

Journal of Pharmacology and Experimental Therapeutics April 1, 1987 Deborah L. Commins, Georgetta Vosmer, R. Virus et al.

(+/-)-3,4-Methylenedioxymethylamphetamine (MDMA) was administered s.c. to rats (10, 20 or 40 mg/kg b. wt.) and guinea pigs (20 mg/kg) twice a day for 4 days, 2 weeks before decapitation. Norepinephrine, dopamine and serotonin (5-HT) levels were assayed in the hippocampus, hypothalamus, striatum and neocortex. In rats, MDMA produced dose-dependent reductions in 5-HT in all brain regions...

Two kinds of modification by 5-methoxy-N,N-dimethyltryptamine of contractile responses to electrical stimulation of isolated guinea-pig vas deferens.

The Japanese Journal of Pharmacology April 1, 1987 S Yoshida, T Kuga

Two kinds of electrical stimulation, low frequency stimulation (5 Hz, 1 msec, 5 pulses, every 20 sec) and high frequency stimulation (30 Hz, 0.1 msec, 20 pulses, every 20 sec), produced contractions in isolated guinea-pig vas deferens. These responses were blocked by alpha, beta-methylene-ATP, but not prazosin. Phentolamine potentiated the contractions produced by low frequency stimulation,...

Contrary to nature : Inuit conception of witchcraft

Scripta Instituti Donneriani Aboensis 1987 Daniel Merkur

The present contribution to the phenomenology of witchcraft will depend for its data on the traditional conceptions, rites, and folklore of witchcraft among the Inuit (Eskimo) of Čanada and Greenland. A phenomenological definition of witchcraft may be obtained through recognition of its position within Inuit religion. Like many native North Americans, the Inuit epitomized their religion in the...

(+)-8-OH-DPAT and 5-MeODMT induced analgesia is antagonised by noradrenaline depletion.

Physiology & Behavior 1987 T Archer, E Arweström, B G Minor et al. 32 citations

In experiments with both rats and mice the 5-HT agonists 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT) and 5-methoxy-N,N-dimethyl-tryptamine (5-MeODMT) were shown to produce reliable analgesic effects after acute administration (1 mg/kg SC) in the tail-flick, hot-plate and shock-titration tests of nociception. Prior treatment with the noradrenaline neurotoxin,...

Effect of the selective 5-HT3 receptor antagonists ICS 205-930 and MDL 72222 on 5-HTP-induced head shaking and behavioral symptoms induced by 5-methoxy-N,N,dimethyltryptamine in rats: comparison with some other 5-HT receptor antagonists.

Psychopharmacology 1987 G T Shearman, L Tolcsvai 8 citations

The effect of the selective 5-HT3 receptor antagonists ICS 205-930 and MDL 72222 on head shaking behavior induced by L-5-HTP and behavioral symptoms induced with 5-methoxy-N,N,-dimethyltryptamine (5-MeODMT) in rats was evaluated. Both drugs dose-dependently reduced L-5-HTP-induced head shaking but were at least 600 times less potent than pirenperone and ketanserin and at least 50 times less...
