在分娩后的4小时内，母羊学会了她的羔羊的气味，这将允许以后识别她的后代。本研究探讨了嗅球（OB）β-去甲肾上腺素能受体激活在建立这种嗅觉记忆中的重要性。妊娠母羊（n= 24）在OB中双侧插管。在分娩前2天，用含有选择性β-去甲肾上腺素能拮抗剂普萘洛尔（10-3 M）的溶液或溶剂连续灌注OB（10 μl/hr）。结果表明，尽管9只对照母羊中有8只仍然能够选择性地与羔羊结合，但15只心得安治疗的动物中只有7只能够结合（p=. 04）。这些结果表明，在分娩期间，OB中的β-去甲肾上腺素能受体的激活是建立羔羊嗅觉识别所必需的。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Within a 4-hr period after parturition, the ewe learns the odor of her lamb that will allow later recognition of her offspring from alien lamb. This study investigated the importance of the activation of olfactory bulb (OB) β-noradrenergic receptors in establishing this olfactory memory. Pregnant ewes (n= 24) were cannulated bilaterally in the OB. Two days before parturition, OB were perfused continuously (10 μl/hr) with either a solution containing the selective β-noradrenergic antagonist propranolol (10–3 M) or vehicle. The results showed that, although 8 of 9 control ewes were still able to bond selectively to their lambs, only 7 of 15 propranolol-treated animals were able to bond (p=. 04). These results suggest that activation of β-noradrenergic receptors in the OB during the period surrounding parturition is required to establish olfactory recognition of the lamb.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
