Musicians spend countless hours practicing their instruments over the course of a lifetime. These hours are primarily spent learning how to manipulate the instrument through scale studies, etudes, and repertoire. However, despite intense and diligent effort, many musicians find themselves unable to perform for an audience without some kind of interruption in creativity in the form of mental...

BackgroundThe anesthetic drug ketamine (KT) has been reported to be an abused drug and fatal cases have been observed in polydrug users. In the present study, considering the possibility of KT-enhanced toxic effects of other drugs, and KT-induced promotion of an overdose without making the subject aware of the danger due to the attenuation of several painful subjective symptoms, the...

RATIONALE: 3,4-Methylenedioxymethamphetamine (MDMA) is a widely abused illicit drug. In animals, high-dose administration of MDMA produces deficits in serotonin (5-HT) neurons (e.g., depletion of forebrain 5-HT) that have been interpreted as neurotoxicity. Whether such 5-HT deficits reflect neuronal damage is a matter of ongoing debate. OBJECTIVE: The present paper reviews four specific issues...

The current study examined the long-term effect of brief exposure to 3,4-methylenedioxymethamphetamine (MDMA) on local cerebral glucose utilization (LCGU) in specific brain regions immediately following administration of the 5-HT2A/2C receptor agonist, 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI). Wistar rats (post-natal day (PND) 28, n = 24) were administered MDMA (5 mg/kg, i.p.) or...

Repeated ecstasy (MDMA) use is reported to impair cognition and cause increased feelings of depression and anxiety. Yet, many relevant studies have failed to control for use of drugs other than MDMA, especially marijuana (THC). To address these confounding effects we compared behavioural performance of 11 MDMA/THC users, 15 THC users and 15 non-drug users matched for age and intellect. We...

Although 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) is a known serotonergic neurotoxin in different animal species, there is to date no conclusive evidence of its neurotoxicity in humans. MDMA use was associated with impairments of psychological well-being, verbal memory and altered serotonergic functioning in a number of crosssectional studies. Due to inherent methodological...

Drawing on phenomenology and his clinical practice, the author explores religious experience and the dynamics of the numinous. The article opens with the argument that psychoanalysts, like religious healers, should be able to work with religious phenomena as part of psychoanalytic therapy. The origin of the term 'numinous' is explained, and two types of human religious experience, mysterium...

Despite the high prevalence of hypnopompic hallucinations in the community, to our knowledge there are no reports that have been published in the English literature of these phenomenon observed by staff in the hospital setting. Psychiatric or neurological evaluation often ensues if a patient reports hallucinations in other circumstances, but when they are reported in connection with sleep,...
