This study represents as an attempt to make sense of a rather curious coincidence. In Philip K. Dick's novel A scanner darkly (1973-1977), a character named Tony Amsterdam experiences a mystical vision after an acid trip. God appears to him in the form of «showers of colored sparks, like when something goes wrong with your TV set». In the same year 1973, a young Bill Viola creates Information,...
Vipassana meditation is characterized by observing bodily sensations, developing emotional and attentional stability, and promoting prosocial qualities. Whether these characteristics are also reflected in meditators’ dream content is not currently known. Evidence relating dream content with sleep-dependent learning is mixed: Some studies suggest that dreaming of a task is beneficial for...
In the rubber hand illusion (RHI), the feeling that a fake hand belongs to oneself can be induced by the simultaneous, congruent touch of the fake visible hand and one's own hidden hand. This condition is also associated with a recalibration of the perceived location of the real hand. A cortical network, including premotor and temporo-parietal areas, has been proposed as the basis of the RHI....
There is a clear need for advancing the treatment of cannabis use disorders. Prior research has demonstrated that dronabinol (oral THC) can dose-dependently suppress cannabis withdrawal and reduce the acute effects of smoked cannabis. The present study was conducted to evaluate whether high-dose dronabinol could reduce cannabis self-administration among daily users. Non-treatment seeking daily...
No medications are approved for cannabis use disorder (CUD). Gamma-aminobutyric acid (GABA) reuptake is modulated by cannabinoid (CB) receptor agonists, and there are shared effects between CB agonists and the GABA reuptake inhibitor tiagabine. This overlapping neuropharmacology suggested that tiagabine might be useful for CUD. The study determined the ability of tiagabine maintenance to reduce...
Major depressive disorder (MDD) is the most common psychiatric illness worldwide, and it displays a striking sex-dependent difference in incidence, with two thirds of MDD patients being women. Ketamine treatment can produce rapid antidepressant effects in MDD patients, effects that are mediated-at least partially-through glutamatergic neurotransmission. Two active metabolites of ketamine,...
Treatment-resistant mood disorders and anxiety disorders require intensive treatment, but treatment options should balance benefits and adverse effects or other potential detrimental effects on patients, including the risk of developing prescription medication addiction. Some of the newer treatment modalities for mood and anxiety disorders may have similar properties to benzodiazepines. The...
Serotonin is a neurotransmitter involved in many psychiatric diseases. In humans, a lack of 5-HT2B receptors is associated with serotonin-dependent phenotypes, including impulsivity and suicidality. A lack of 5-HT2B receptors in mice eliminates the effects of molecules that directly target serotonergic neurons including amphetamine derivative serotonin releasers, and selective serotonin...
The assessment of the talent of the Delphic Pythia was ambiguous among Greeks. On the one hand, they emphasized the role of Apollo in the process, saying that becoming a Pythia requires no special ability or education. On the other hand, they admitted that the Pythia infl uences the poetic quality of the oracle. Despite the modern popular view, the Delphic oracles did not require a secondary...
Phenomenology, clinical diagnostics and treatment of hallucinations Abstract. Hallucinations are perceptions without any stimulus. They occur typically in schizophrenia, but they can be found in other psychiatric or medical disorders as well. Recently, hallucinations have been increasingly reported to occur with a high prevalence in the general population and they are conceptualised as...
