چکیده

The marble burying test is a simple behavioral psychopharmacology task in which rodents, especially rats and mice, are exposed to glass marbles laying on thick bedding materials. This test has been widely used to assess the effects of a variety of psychoactive drugs. Although the marble burying test clearly reflects drug efficacy, many aspects of the behavior itself remain unclear. In the present study, we assessed the effects of different bedding materials and the number of glass marbles presented on the marble burying behavior of mice (C57BL/6J). Six (bedding materials) three (number of glass marbles) factorial experiments revealed that the number of marbles buried correlates closely with the quality of the bedding material. Our results provide a basic understanding of certain factors that govern marble burying behavior, which may be applicable to behavioral sciences including psychopharmacology.

Differences in BTBR T+ tf/J and C57BL/6J mice on probabilistic reversal learning and stereotyped behaviors.

Autism spectrum disorders (ASD) represent a class of neurodevelopmental disorders characterized by impairments in social interaction, verbal and non-verbal communication, as well as restricted interests and repetitive behavior. This latter class of symptoms often includes features such as compulsive behaviors and resistance to change. The BTBR T+ tf/J mouse strain has been used as an animal mod...

Oxotremorine treatment reduces repetitive behaviors in BTBR T+ tf/J mice

Repetitive behaviors with restricted interests is one of the core criteria for the diagnosis of autism spectrum disorder (ASD). Current pharmacotherapies that target the dopaminergic or serotonergic systems have limited effectiveness in treating repetitive behaviors. Previous research has demonstrated that administration of muscarinic cholinergic receptor (mAChR) antagonists can exacerbate moto...

N-acetyl-L-cysteine inhibits marble-burying behavior in mice.

In the present study, we examined the effect of N-acetyl-L-cysteine (NAC), a glutamate-modulating agent, on marble-burying behavior in mice. Fluvoxamine (30 mg/kg, p.o.) and mirtazapine (3 mg/kg, i.p.) significantly inhibited marble-burying behavior without affecting locomotor activity. Similarity, NAC (150 mg/kg, i.p.) significantly inhibited marble-burying behavior without affecting locomotor...
