摘　　要：利用10只北京鸭脑制成的连续切片，经Nissl法染色，光镜观察分布于中脑顶盖前区内的中脑豆状核、顶盖前核、螺旋外侧核、螺旋内侧核和后连合核的形态及细胞构筑。结果表明：1.北京鸭的中脑豆状核主要位于中脑，由致密部和分散部组成，细胞为中等大小；2.北京鸭的螺旋外侧核与螺旋内侧核分界不明显；3.北京鸭后连合核与鸡的后连合背核相当，但位置有些差异；4.北京鸭的顶盖前核与其他禽类的相同。The serial section of ten Pekin ducks' brains which were stained by Nissl method were used to observe the morphology and cytoarchitecture of the nucleus lentiformis mesencepholi(LM), nucleus spirifomis lateralis(SPL), nucleus spiriformis medialis(SPM), nucleus pretectalis(PT), Nucleus commissuralis posterior (nCP), which lie in the midbrain areas pretectalis. The results are that follow: 1.The LM of Pekin duck is main situated the mesencephalon and is contained in LMd and LMc, it is composed of medium sized cells. 2.SPL and SPM can not be divided clearly; 3.nCP of Pekin duck is equal to the nucleus commissuralis posterior dorsal, but the situation is different to chick. 4.PT of Pekin duck is similar to one of which was previously observed in the other bird.
