Bipolar disorder is a chronic disease characterized by recurring episodes of mania and depression that can lead to disability. This study investigates the protective effects of edaravone (3-methyl-1-phenyl-2-pyrazolin-5-one), a drug with well-known antioxidant properties, in a model of mania induced by ketamine in rats. Locomotor activity was assessed in the open-field test. Superoxide...
According to current international drug policy, psychedelic drugs share the same abuse and ad-dictability potential as heroin. The presumption is that acknowledging any different would not only pose a threat to the safety and health of society but would compromise established moral values. Legislators have created a campaign against psychedelics since their revival in the 1960s, fighting a war...

Repeated administration of non-competitive N-methyl-d-aspartate (NMDA) receptor antagonists such as phencyclidine (PCP) to rodents causes long-lasting deficits in cognition and memory, and has effects on behaviors that have been suggested to be models of the cognitive impairment associated with schizophrenia (CIAS). Despite this being a widely studied animal model, little is known about the...

Hemodynamic correlates of consciousness were investigated in humans during the presentation of a dichotic sequence inducing illusory auditory percepts with features analogous to visual multistability. The sequence consisted of a variation of the original stimulation eliciting the Deutsch's octave illusion, created to maintain a stable illusory percept long enough to allow the detection of the...
Cannabis (Cannabis sativa, Cannabis indica) is the illicit drug most frequently abused by young men and women. The growing use of the drug has raised attention not only on the impact of direct exposure on the developing brain and behavior later in life, but also on potential cross-generational consequences. Our previous work demonstrated that adolescent exposure to Δ9-tetrahydrocannabinol...
As more states and countries legalize medical and/or adult recreational marijuana use, the incidences of prenatal cannabis exposure (PCE) will likely increase. While young people increasingly view marijuana as innocuous, marijuana preparations have been growing in potency in recent years, potentially creating global clinical, public health, and workforce concerns. Unlike fetal alcohol spectrum...
We have read with great interest the report by Wiltshire et al.,1 which suggests a possible link between the death of a healthy young man in southwest England in 2008 and the South American botanical hallucinogen ayahuasca. This study is important as it highlights the complex link between life-threatening reactions and the ingestion of ayahuasca.2 However, the study has several important...
