Abstract

Ontogenetic changes in pup-elicited maternal corticosterone responsiveness were investigated. Patterns of maternal corticosterone change were found to depend on pup treatment: shocked pups elicited larger corticosterone elevations than pups that had been handled. In addition both the age of the stimulus pups and the state of lactation when the mother was tested affected the pattern and magnitude of maternal pituitary-adrenal activity.

摘要

研究了幼崽引发的母体皮质酮反应性的个体发育变化。发现母体皮质酮变化模式取决于幼崽的处理方式：受惊吓的幼崽比经过抚摸的幼崽引发的皮质酮升高幅度更大。此外，刺激幼崽的年龄以及测试母亲时的泌乳状态都会影响母体垂体 - 肾上腺活动的模式和幅度。
