Evaluation of Environmental Enrichment and Pup Exposure on Maternal Behavior Sensitization Latencies in Virgin Female RatsPublic
Downloadable Contentopen in viewer
Adult, virgin female rats do not spontaneously display maternal behavior, but can be "sensitized" to display such behaviors through 5-7 days of continuous exposure to foster pups. The purpose of this study was to decrease the anxiety of the animals through environmental enrichment, and to determine if the resulting reduced stress would stimulate faster maternal behavior onset, therefore reducing the number of animals needed in the maternal behavior sensitization testing paradigm. However, animals in an enriched environment displayed longer maternal behavior onset latencies.
