However, the advance of intracellular labeling techniques enables us not only to visualize more complete dendritic arbor for qualitative analysis, but also to examine the relation between changes in the dendritic arborization and the evoked fast postsynaptic curents - 3 - ( fpscs ) in the same neurons during the postnatal development the aim of this study was to systematically examine the postnatal changes in the configuration of fpscs evoked by the focal stimulation of the stratum radiatum of the ca1 region, and the relationship between the dendritic arborization and evoked fpscs in the rat hippocampal ca1 pyramidal neurons using whole - cell blind patch recording technique combined with biocytin intracellular labeling during the postnatal development ( postnatal day 2 - 70, p2 - p70 )
但是，細胞內染色技術的進步使我們不僅能觀察到更完整的樹突分支來用於定性研究，而且也可以在同一神經元上研究在發育過程中樹突分支的變化與誘發的快突觸后電流（ fastpostsynapticcurrents ， fpscs ）之間的關系。因此，本研究應用盲法腦片膜片鉗記錄並結合biocytin細胞內染色方法，對發育過程中（生后2 70天）局部刺激大鼠海馬ca1區輻射層在錐體神經元誘發的fpscs的成分變化，以及ca1錐體神經元的樹突分支與誘發的fpscs的關系進行了較為系統的研究。Myeloid dendritic cells, which contribute to an immunologic synapse responsible for activation of the adaptive immune system, are abundant within muscle in inclusion body myositis and polymyositis

一旦軸突連上了頂蓋神經元的樹突分枝，就會在其間形成突觸，哇啦，同時激發的神經元就串連在一起了。Fos + / th + / gfap + and fos + / vp + / gfap + triple labeled n - asc could be found in the mvz, pvn and son respectively ; ( 2 ) under electronic microscope, the astrocytic processes connected closely with the dendrites or axons of the neurons, where the bilateral membranes became thick. we call transiently it electron - dense areas ( edas ). the number of edas increased remarkably following hyperosmotic stimulation ; ( 3 ) when trace retrogradely, wga - hrp was microinjected into the unilateral son, pvn or nucleus of solitary tract ( nts ) respectively using the stereotaxic method, the n - ascs formed by the neurons triple - labeled with hrp / fos / th ( or vp ) and astrocytes labeled with gfap could be found in the mvz, son and pvn respectively ; ( 4 ) after being treated with heperosmotic nacl solution, intracellular calcium concentration in cultured hypothamic neurons and astrocytes increased and then decreased
腦內gfap陽性結構也明顯增多，其分佈與fos陽性細胞分佈基本一致，表現為胞體肥大、突起粗長； ast緊密包繞在神經元周圍形成神經元- ast復合體（ n - asc ） ；在mvz 、 pvn和son三重免疫組化染色切片上可見到fos + th + gfap +第四軍醫大學博士學位論文和fos vp gfap三重標記asc ； （ 2 ）免疫電鏡下son內星型膠質細胞突起與神經元樹突或軸突之間接觸部位出現增厚的膜結構一電于緻密區（ edas ） ，高滲刺激后數量明顯增多： （ 3 ）將們個mp注入大鼠一側n卜、卜卜或孤束核（ ws ） ，分別在延髓內臟帶（ mvz ） 、 so和pvn內出現fos hrp th 、 fos hrp八p三重標記神經元和gfap陽性標記ast形成的n asc ； （ 4 ）高滲刺激使培養神經元和ast內鈣水平先升高后降低，最後維持在比高滲刺激前稍高的靜息鈣水平上。Effects of transcranial magnetic stimulation on learning and memory, morphology and ultrastructure of contralateral hippocampal ca3 pyramidal neurons in rats with cerebral infarction
經顱磁刺激對腦梗死大鼠學習記憶與健側海馬錐體細胞樹突和突觸結構的影響Thus, correlated pre - and postsynaptic activity alters not only the strength of the activated input, but also its dendritic integration with other inputs
因此，突觸前後神經元的相關活動不僅影響被激化突觸的傳遞效率，還影響樹突的信號整合特性。Neurons p2 to p5 were diverse in both growth of the apical dendrite and generation of the evoked fpscs, and the total length and number of branches of apical dendrites were significantly longer or larger in neurons producing fpscs than in neurons producing no fpscs
在生后2 ? 5天，錐體神經元不僅在頂樹突的發育上，而且在fpscs的產生上均呈現多樣性，且可產生突觸反應的神經元的頂樹突的總長度及分支數量均明顯長于或多於不能產生突觸反應的神經元。I have 10 billion neurons in my brain and you do too. everybody does, young or old. they are held in place by 90 billion glial cells linked together electronically through branches called dendrites to roots, called neurotransmitters
我的腦袋有一百億個神經細胞，你也有，每個人都有不論是老是少，它們在九百億個細胞里，由樹狀突連系起來，根部稱為突觸，突觸是用作釋放神經傳送素的。Because dendritic spines are the sites of connection between neighbouring nerve cells, the increased number may mean more activity in the fathers ' brains than in those of the non - fathers
由於樹突棘是領近神經細胞之間相接觸的地方，因此樹突棘數量的增多可能意味著父絨猴大腦內的活動比非父絨猴的要多。There have been a mass of research documents showing that many visual functions deteriorate with age both for human beings and for animals. age - related visual function decline could not be completely attributed to optical and retinal changes. considerable visual impairments in the old might result from morphological ( such as cell loss, dendritic change and synaptic density decrease ) or functional ( such as weakened gaba inhibition ) degeneration of visual pathways. in this article we made preliminary studies on the mechnisam underlying visual function degradation by electrophysiological and morphological methods
隨著年齡的增長，人及動物的許多視覺功能出現衰退，老年性視覺能力降低並非完全由眼的光學因素和視網膜形態、功能變化導致，不少方面可能決定於衰老引起的視覺中樞結構（如神經元丟失、樹突野改變及突觸密度下降等）和生理功能（如皮層內gaba能抑制作用減弱等）的改變。Information processing in the neuron requires spatial summation of synaptic inputs at the dendrite
不同空間和時間的突觸活動在樹突上的整合過程是神經元信號處理的重要環節。In ca1 pyramidal neurons of the hippocampus, a brief period of correlated pre - and postsynaptic activity, which induces long - term potentiation ( ltp ) or long - term depression ( ltd ), results in a persistent increase or decrease in the linearity of spatial summation, respectively
在海馬ca1神經元上，短暫的突觸前後神經元的反復相關活動除誘導長時程的突觸增強或抑制以外，還能持久地提高或降低樹突空間整合的線性度。The results are consistent with contact - dependent signaling between dendritic protrusions and astrocyte processes during the formation of dendritic spines
在形成樹突脊的過程中樹突狀突起與星形膠質細胞相互作用的信號傳導是接觸依賴性的，本研究結果與之一致。Dendritic protrusions stabilized after making contact with astrocytes, such that protrusion lifetimes were longer if contact occurred
樹突狀突起與星形膠質細胞相互作用以後更加穩定，因此這種接觸發生后突起壽命會延長。分享友人
