Abstract
Exposure to environmental enrichment (EE) reduces sucrose seeking by rats with a history of sucrose self-administration. The present experiment examined whether acute or chronic EE also reduces brain Fos levels, a protein marker indicative of neuronal activation. Fos levels were also examined after either 1 or 30 days of forced abstinence to examine whether Fos levels vary with the incubation of sucrose craving. Fos expression was examined in 18 regions and was identified in brain slices using immunohistochemistry. Fos levels were higher in most regions after 30 days of forced abstinence and were decreased in most regions by either acute or chronic EE. Eleven regions had some statistically significant effect and/or interaction of EE or incubation on Fos; the most salient of these are listed here. In the prelimbic cortex, there was an incubation of Fos and EE reduced Fos at both forced abstinence time points. In contrast, in the orbitofrontal cortex, there was no Fos incubation but EE reduced Fos at both forced abstinence time points. An interaction of EE and incubation was observed in the anterior cingulate cortex and nucleus accumbens core and shell where Fos incubated but EE only decreased Fos at the day 30 forced abstinence time point. In contrast, in the dorsolateral striatum Fos incubated, but EE robustly decreased Fos expression at both forced abstinence time points. These differential expression patterns provide rationale for more detailed, site-specific molecular functional studies in how they relate to the ability of EE to reduce sucrose seeking.
