大白鼠脑干听觉中枢的研究下丘中心核内神经突触的特点

1.大白鼠下丘中心核(the Central Nucleus of the Inferior Colliculus,ICCN)内神经末稍以群体的形式有在,神经突触排列的类型主要为系列突触.2.末稍群体(Clustered ending)中轴突终末内含有多种类型的突触小泡.3.ICCN内具有不对称突触与对称突触两种类型的突触结构.4.在ICCN内,突触前终末有大量的突触小泡聚集,并且在突触后常有1—2个大线粒体靠近突触后膜.5.以上结果表明了脑干听觉中枢下丘中心核的结构及其突触连结的模式;突触的结构及其特点,这是频有意义的.

STUDIES ON THE AUDITORY CENTER OF THE BRAINSTEM OF THE RAT CHARACTERISTICS OF THE SYNAPSES IN THE CENTRAL NUCLEUS OF THE INFERIOR COLLICULUS

1.Usually, there are different types of terminals of axon and dendrite which form a clustered ending in the Central Nucleus of the Inferior Colliculus(ICCN) . The synaptic arrangements in ICCN is mainly serial.2. There are various components of the synaptic vesicles within the axon ter- minals of the clustered ending.3.Types of the synaptic structures in ICCN have been shown. One is the asymmetrical synapse, the other is the symmetrical synapse.4.A large number of the synaptic vesicles of ICCN often appear within the presynaptic terminals. It is also observable that there is one or two large mitochondria near the postsynaptic membrane.5.The results demonstrated the structure of the synapses, the types of synaptic arrangements, synaptic organization and its characteristics of the Central Nucleus of the Inferior Collisulus in the auditory center of the brainstem of the rat.
