Aripiprazole and its adverse effects in the form of impulsive-compulsive behaviors: A systematic review of case reports
AbstractAripiprazole is an efficacious treatment for both the positive and negative symptoms of schizophrenia and is also commonly used as a mood stabilizer. It is associated with better tolerability compared with other antipsychotics. However, there are reports of patients who experience problem gambling, hypersexuality, obsessive –compulsive symptoms, and other impulsive and/or compulsive behaviors as a result of aripiprazole administration and/or dosage increase. We aimed to do a systematic review of case reports published in this regard. After screening more than 6000 titles and abstracts in ten scientific search eng...

Pharmaco-toxicological effects of the novel tryptamine hallucinogen 5-MeO-MiPT on motor, sensorimotor, physiological, and cardiorespiratory parameters in mice —from a human poisoning case to the preclinical evidence
ConclusionsConsumption of 5-MeO-MiPT can affect the ability to perform activities and pose a risk to human health status, as the correspondence between the effects induced in mice and the symptoms occurred in the intoxication case suggests. However, our findings suggest that 5-MeO-MiPT should not be excluded from research in the psychiatric therapy field. (Source: Psychopharmacology)

Effects of social housing conditions on ethanol-induced behavioral sensitization in Swiss mice
ConclusionsThese results are consistent with the idea that higher levels of acute and sensitized ethanol stimulant effects are observed in mice housed in stressful housing conditions, such as social isolation. (Source: Psychopharmacology)

Pharmacological diacylglycerol lipase inhibition impairs contextual fear extinction in mice
AbstractAcquisition and extinction of associative fear memories are critical for guiding adaptive behavioral responses to environmental threats, and dysregulation of these processes is thought to represent important neurobehavioral substrates of trauma and stress-related disorders including posttraumatic stress disorder (PTSD). Endogenous cannabinoid (eCB) signaling has been heavily implicated in the extinction of aversive fear memories and we have recently shown that pharmacological inhibition of 2-arachidonoylglycerol (2-AG) synthesis, a major eCB regulating synaptic suppression, impairs fear extinction in an auditory cu...

Insight into differing decision-making strategies that underlie cognitively effort-based decision making using computational modeling in rats
ConclusionsModeling revealed the decision-making processes that are associated with cognitive effort costs, and how these differ across individuals. Reanalysis of drug data provided insight into the mechanisms through which different neurotransmitter systems impact cognitively effortful attention and decision-making processes, with relevance to multiple psychiatric disorders.
