Glutamatergic abnormalities in several brain regions, including the ventromedial orbitofrontal cortex (vmOFC) and prefrontal cortex (vmPFC), have been implicated in the pathophysiology of obsessive-compulsive disorder (OCD). (R, S)-ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, and enantiopure (S)-ketamine may have therapeutic effects in patients and animal models of OCD....

3,4-methylenedioxymethamphetamine (MDMA), a commonly abused recreational drug, induces prosocial effects such as increased sociability and empathy. The nucleus accumbens (NAc) has been suggested to play a crucial role in these MDMA-mediated prosocial effects. However, the relationship between social behavior and NAc neural activity, and the effects of MDMA on this relationship, remain unknown....

Ketamine, an N-methyl-D-aspartate receptor antagonist, exerts rapid and sustained antidepressant actions. Preclinical studies demonstrated that the release of brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor in the medial prefrontal cortex (mPFC) is essential for the antidepressant-like effects of ketamine. However, the role of other neurotrophic factors in the...

N-[[1-(5-fluoropentyl)-1H-indazol-3-yl]carbonyl]-L-valine methyl ester (5F-AMB) is a synthetic cannabinoid that has been distributed recently. Although inhalation of 5F-AMB produces adverse effects, such as impaired memory and disturbed consciousness, in humans, the psychopharmacological effects of 5F-AMB in rodents have not been investigated. We first examined the effects of intraperitoneal...

5F-AMB is one of the synthetic cannabinoids (SCs) designed to potentiate the ability to activate cannabinoid 1 (CB1) receptors and is abused worldwide. Although inhalation of 5F-AMB elicits serious adverse effects including impaired memory and consciousness, it is not known whether and how 5F-AMB affects the activity of pyramidal neurons in the medial prefrontal cortex (mPFC), a brain region...
