Effects of environmental enrichment on exploratory behavior, win-stay and lose-shift performance, motor sequence learning, and reversal learning during the three-lever operant task in mice.

Beneficial effects of environmental enrichment (EE) on the central nervous system have been demonstrated. Although the effects of EE on spatial learning have been extensively studied, studies on reward-based motor learning are limited. In this study we examined the effects of EE on the performance of operant tasks using three levers (A-C).

Oxytocin administration modulates the complex type of ultrasonic vocalisation of mice pups prenatally exposed to valproic acid.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterised by communication disability with no curative treatment. Maternal separation-induced ultrasonic vocalisation (USV) was widely used to assess communication disability between pups and dams. Particularly, USV calls in many genetically modified ASD model mice were altered.

Oxytocin ameliorates maternal separation-induced ultrasonic vocalisation calls in mouse pups prenatally exposed to valproic acid.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder estimated by the World Health Organization to occur in one of 160 children worldwide. No pharmaceutical treatments are available to improve the deficits in social communication that are common symptoms of ASD. Recent clinical trials have focused on the nasal application of oxytocin, a neuronal peptide known to regulate a variety of social behaviours.
