Expression of Fos-related antigens in the nucleus accumbens and associated regions following exposure to a cocaine-paired environment.


This study examined whether conditioned hyperactivity measured in a cocaine-paired environment was associated with increased expression of Fos-related antigens (FRA) within the nucleus accumbens (NAc) and associated forebrain regions of rats. Three groups of rats were given repeated injections of either cocaine in the test environment and saline in the… (More)
