One earlier study found that after about an hour, pups began to exhibit a second, passive stage of responsiveness marked by a crouched stance, eye-closing, and extensive piloerection.(More)
We have proposed that passive responses observed following maternal separation in guinea pig pups represent "stress-induced sickness behaviors" mediated by proinflammatory processes. In this study, the anti-inflammatory peptide, alpha-melanocyte stimulating hormone (alpha-MSH) administered intracerebroventricularly, but not intraperitoneally, reduced the(More)
