In 22 adult sharks representing eight species, the mesencephalic trigeminal nucleus (Mes V) was examined employing the Romanes reduced silved method. Morphological evidence is presented of extensive development of neurites and intranuclear communication among Mes V cells of sharks, as well as their apparent innervation by extranuclear neurons. Species differences and the possible significance of the morphology of the Mes V in sharks to certain aspects of their behavior are discussed. A brief comparison of the Mes V of elasmobranchs and those of reptiles and mammals is included.
采用罗曼斯还原银染法，对代表8个物种的22条成年鲨鱼的中脑三叉神经核（Mes V）进行了检查。文中提供了形态学证据，证明鲨鱼Mes V细胞间神经突广泛发育且存在核内通讯，以及它们明显受核外神经元支配。讨论了物种差异以及鲨鱼Mes V形态对其某些行为方面可能具有的意义。还对板鳃亚纲动物与爬行动物和哺乳动物的Mes V进行了简要比较。
