| 摘 要： | 观察了泥鳅（Misgurnus Anguillicaudatus）脑的显微结构。结果表明,泥鳅的脑组织基本结构与多数鱼类相一致,其脑轮廓狭长,包括端脑、间脑、中脑、小脑及延脑五部分,视叶隆起,小脑瓣突入中脑室内,延脑有核团的分化。同时与其生存环境和捕食习性相适应,泥鳅脑具有一些原始的特征,包括：嗅叶及嗅束分化较明显,大脑呈长椭圆状,仍保留鲤科（Cyprinidae）鱼类脑的原始特征;中脑视叶壁偏薄,与视觉不甚发达相关;小脑不发达,与其喜静的生活习性相适应;延脑前部稍稍隆起,面叶发达与其须感知食物的习性相符。

| Abstract: | The anatomical structure of the brain of loach(Misgurnus Anguillicaudatus) was described through microscopic observations.As indicated by the research results,the loach brain has a long shape and is consist of telencephalon,diencephalon,mesencephalon,cerebellum and myelencephalon.And it has a outstanding lobus opticus.The valvula cerebelli protruded into the optic cavity.The nucleus of the mylencephalon has specialized,which is similar to the brain of most of teleosts.But corresponding to its living conditi... |
