Ayahuasca drinking using a two-bottle choice procedure in male mice.

Ayahuasca has been proposed as a treatment for substance use disorders. However, because of its hallucinogenic properties, studies investigating its abuse potential are needed. The aim of the present study was to investigate voluntary ayahuasca drinking in male mice using a two-bottle choice procedure.

Individual differences in the effects of midazolam on anxiety-like behavior, learning, reward, and choice behavior in male mice.

Introduction: The aim of the present study was to investigate the behavioral effects of the benzodiazepine midazolam in male mice, in models of anxiolysis, learning, and abuse-related effects.

Methods: In a first set of experiments, male Swiss mice were submitted to the training session of a discriminative avoidance (DA) task on the elevated plus maze to evaluate anxiety-like behavior and learning after vehicle or midazolam (1, 2 or 5 mg/kg, i.g.

Role of 5-HT receptors in the effects of ayahuasca on ethanol self-administration using a two-bottle choice paradigm in male mice.

Rationale: Ayahuasca has been proposed as a potential treatment of alcohol (ethanol) use disorder (AUD). The serotonin 5-HT receptor agonist N,N-dimethyltryptamine (DMT) is the main psychoactive component of ayahuasca, suggesting that its therapeutic effects may be mediated by 5-HT receptors.

Objectives: The aim of the present study was to investigate the effects of ayahuasca on the expression of ethanol self-administration using a two-bottle choice procedure and the role of 5-HT receptors in those effects.
