Abstract
Latency to onset of maternal behavior increases progressively from the weanling to the peripubertal period in female and male Long-Evans rats. Gonadectomy or hypophysectomy on day 21 had no influence on the pubertal decline in maternal responsiveness. Apparently, inhibitory neural pathways mature which are independent of pituitary hormonal influences.
摘要
在雌性和雄性Long-Evans大鼠中，从断奶期到青春期，母性行为开始的潜伏期逐渐增加。在出生后第21天进行性腺切除或垂体切除，对青春期母性反应性的下降没有影响。显然，独立于垂体激素影响的抑制性神经通路成熟了。
