Cold water stress analgesia in rats: differential effects of naltrexone.

abstract：:Zebrafish (Danio rerio) have been widely used to study the molecular mechanisms of development including neurodevelopment. More recently, they have begun to be used to study neuropharmacology and neurotoxicology. Critical for this line of research are methods to study behavioral function in zebrafish. Previous studies...
