TL;DR: Pretreatment with cortisol, in the first stress session, did not prevent the development of the enhanced fast feedback when restressed, suggesting that stress-restress paradigm might serve as a good animal model for HPA abnormalities found in PTSD patients.

TL;DR: The current studies demonstrate that stress increases oxytocin receptor binding in areas of the CNS that are rich in glucocorticoid receptors, such as hippocampus, which suggests differential regulation of Oxytocin receptors in CNS, depending upon their functional role in different regions.

TL;DR: The results demonstrate that oxytocin produces a reliable and robust preference for the environment with which it is repeatedly associated, and has rewarding or potentially anti-aversive properties.
