Motherhood, Memory And Aging : Object Recognition Performance, Julia Margaret Friedenberg
Master's Theses
Reproductively experienced female rats have been shown to have attenuated stress responses, improved visual systems, and better memory and learning. This study sought to extend those findings by comparing aged reproductively experienced and aged virgin female rats on an object recognition task, as well as comparing levels of corticosterone and 17p-estradiol and neural activation. Multiparous (MP, 2 reproductive experiences) females performed better on the task and demonstrated quicker habituation to the task than nulliparous (NP, no reproductive experiences) females. No hormonal or neural activation differences were found. The present study contributes to the growing research areas of reproductive experience and …

Intricacies Of Development : The Impact Of Maternal Experience And Isolation On The Social Development Of Juvenile Male Rats, Lillian Maria Christon
Master's Theses
Reproductive experience induces changes in females. Parity-related differences in maternal treatment of offspring can induce enduring changes in offspring. The relationships between maternal experience, early social isolation, and development were explored in rodents in this experiment. Male rats were weaned from multiparous (MP) and primiparous (PP) mothers and placed into isolation or social housing for four weeks. They were then observed in a social-interaction test. Social behavior and neural oxytocin and vasopressin were assessed post-testing, while corticosterone levels were measured across the four weeks. Weaning was extremely stressful for all offspring. PP- and MP-raised pups exhibited differences in social behavior, …
