【摘要】 应用改良Golgi法,发现大鼠、猫和人的内、外侧■核都可分Ⅰ型有棘细胞和Ⅱ型无棘细胞。大鼠的■扶树突分支少;猫多;人最多。大鼠的Ⅰ型细胞棘量少,分布始于次级树突;猫的棘量多,分布于各级树突;人的棘最丰富,分布于各级树突和胞体。超微结构显示:人缰量核内,神经毡最发达,神经终末内小泡种类最多。提示人缰按的机能最为复杂。更多还原

【Abstract】 The structures of habenular nuclei of 42 cases of rat, cat and man were studied with modified Golgi method or EM.The cells of habenular nuclei in those species can be classified into spiny type I and aspiny type II(2). In rat the habenular neuron had dendrites with a few branches and type I cells with sparse spines begining on the secondary dendrites. In cat there were more dendritic branches and more soines on all branches of type I(1) cell. Man had bountiful branches and fertile spines even on the cell body. The neuropil of man was well developed with various kinds of vesicles in the nerve terminals. These were suggested that the function of hebanular nucleus of man was the most complicated among them.更多还原
