Abstract
Intraventricular B-chlornaltrexamine (2 micrograms) increased distress vocalizations (DVs) in chicks, and reduced the ability of intraventricular morphine (.1-.5 micrograms), to inhibit DVs. Object imprinting was not blocked by central CNA, but systemic naloxone (10 mg/kg) did attenuate imprinting to a green but not a red object.
摘要
脑室内注射B-氯诺美汀（2微克）会增加雏鸡的痛苦叫声（DVs），并降低脑室内注射吗啡（0.1 - 0.5微克）抑制痛苦叫声的能力。中枢注射CNA不会阻断物体印记，但全身注射纳洛酮（10毫克/千克）会减弱对绿色物体而非红色物体的印记。
