A hypothesis on the physiological conditions of consciousness is presented. It is assumed that the occurrence of states of consciousness causally depends on the formation of complex representational structures. Cortical neural networks that exhibit a high representational activity develop higher-order, self-referential representations as a result of self-organizing processes. The occurrence of...

The epistemological-methodological constraints for an approach to dream as an object of scientific-experimental investigation are pointed out, along with the suggestion of a new memory paradigm, that utilizes the linguistic convention ('word play') proposed by Wittgenstein. A model of dream generation is proposed, in which mnemonic materials activated from long-term memory stores enter the...

Among the various functions of sleep, one is particularly significant for our mental life: that of producing dreams. This specifically human experience, which takes place only during sleep, is closely related with neurophysiological events. The coincidence between mental and biological events raises a complex epistemological question concerning the close relationship between dreams, viewed as a...

Norharman (20 mg/kg, i.p.) and ibogaine (40 mg/kg, i.p.) significantly attenuated naloxone (4 mg/kg, i.p.)-precipitated withdrawal syndrome in morphine-dependent rats. Several withdrawal signs, such as teeth-chattering, chewing, penile licking and diarrhoea, were decreased by both norharman and ibogaine. In addition, norharman reduced also the withdrawal grooming and rearing. It is concluded...

To elucidate the biological activity of natural metabolites of phencyclidine (PCP), we examined the behavioral effects of a major metabolite, the trans isomer of 4-phenyl-4-(1-piperidinyl)cyclohexanol [(trans)PPC], in mice, (Trans)PPC caused dose-related increase in locomotor activity and rearing in mice when injected intraperitoneally at the doses ranging from 10 to 30 mg/kg. (Trans)PPC at any...
