2 . glomeruli are distinguished by their dense neuropil compared with peripheral coarse neuropil . almost all the synapses in the antennal lobe take place within the glomeruli ( 2 )嗅觉纤维球是由神经纤维组成的神经纤维网，大量的突触联系在神经纤维之间发生。

All neuropil regions of optic lobe , the lamina , medulla and lobula , contain 5 - ht immunoreactive varicose fibers , which are distinct in morphology and degree of staining 结果发现， 5 - ht分布很丰富，阳性纤维起源于少量的细胞体，但分布广泛，呈现明显的静脉曲张状。

The ratio of planocera reticulata , pheretima tschiliensis and nereis pelagica was 19 . 00 % , 20 . 13 % and 12 . 82 % . the conclusion of this study is the animal with strong motor ability and developed sense organ has little neuron body and more neuropil in ganglion 甲壳纲动物神经元胞体占神经节的比例最小(虾蛄和平背蜞神经元胞体所占神经节的比例分别为11 . 43和15 . 53 ) 。
4.
The results are as follows : 1 . there are many spheroidal glomeruli in the antennal lobe , either as individuals or in combination , surrounded by neuron cells , coarse neuropil , i . e . nonglomeruli region and more or less glia or glial processes 结果发现： ( 1 )日本弓背蚁触角叶中分布许多大小不一，近似球形的嗅觉纤维球。这些纤维球的分布是不连续的，被神经元细胞群、非嗅觉纤维球纤维分开。

Methods an immunohistochemical staining method was used . results nk3 receptor - li was localized in somatic and dendritic profiles in the most parts and in neuropil in a few regions of the mouse central nervous system 应用免疫组织化学染色方法对小鼠中枢系统内nk3受体的分布进行了观察，结果表明：在小鼠中枢神经系统的绝大部分区域， nk3受体样免疫阳性产物位于胞体和树突上，少部分区域位于神经毡( neuropil )内。
6.
In the ventral hippocampus , median and intralaminar nuclei of the thalamus and interpeduncular nuclei , nkr - li was localized in neuropil . colocalization of nig - li and vp were studied in paraventricular nucleus and superoptic nuclei . the excited nk3 - containing neurons expressed fos in major part neurons of paraventricular nucleus 在室旁核和视上核双标神经元占nk3第四军医大学博士学位论文阳性神经元总数的65和42 ，占加压素阳性神经元总数的60和39 。

Using colophony - paraffin ( cp ) embedding tissue section technique and immunohistochemical streptalidin - peroxidase ( sp ) method , we have investigated the distribution of 5 - ht neurons in the brain of camponotus japonicus ( big worker ant ) , compared the immunoreactivity with gaba , and primarily discussed the character of 5 - ht distribution . the results show that 5 - ht immunoreactive processes originate from a relatively small number of cell bodies but each neuron has processes over a large volume of the neuropil of the brain 本实验采用树脂石蜡( cp )组织包埋切片技术和链霉菌抗生物素蛋白-过氧化物酶( sp )免疫组织化学方法，研究了5 - ht能神经元在日本弓背蚁( camponotusjaponicus )大工蚁脑中的分布情况，并与gaba的分布进行了比较，初步探讨了5 - ht在各个脑区的分布规律和特点。
