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。It consists of fusiform neurons with intensely expressed neuropeptides in the fibers, terminals, and neuronal somata. functional connections between the mrd and hippocampus, amygdala and the basal nucleus of meynert were identified by c - fos expression method [ 14 ]

到目前為止,還未見對發育過程中大鼠海馬ca1錐體神經元總突觸反應的生后發育進行研究的報道,因此對發育過程中誘發的突觸反應進行系統的研究有利於闡明ca1錐體神經元對神經信號的發育整合。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。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。General principles for activities of nervous ; synapse and synaptic transmission ; the basic process of classical synaptic transmission ; postsynaptic potential : excitatory postsynaptic potential and inhibitory postsynaptic potential ; the conception of transmitter and receptor : mostly transmitter and receptor system ; reflex and reflex arc ; the characters of central excitatory transmission, central inhibition ; the motor unit of skeleton muscle ; stretch reflex ; the function of autonomic nervous system and their chemistry transmission

施加在突觸后神經元上的、使其減少發出沖動的一種影響。An influence on a post - synaptic neuron which enhances the probability that the neuron emits a spike
對突觸后神經元的一種影響,它增強神經元發放沖動的概率。The concomitant application of dl - 2 - amino - 5 - phosphonopentanoic acid ( aps, 100 jim ) with bicuculline did not eliminate the polysynaptic second component, but the second component was only elicited in slices in which the ca3 region was kept intact. moreover, the bicuculline - and ap5 - resistant second component was due to the burst activity of ca3 pyramidal neurons, which were antidromically excited by the stimulation of the schaffer collaterals
在生后1121天,神經元的快興奮性突觸后電流( fstexcitatorypostsynapticcllntntsfepscs )出現了典型的多突觸第二種成分,同時給予nmda受體阻斷劑aps不能消除此多突觸第二種成分,但其只有在ca3區保持完整的腦片上才可被引出。So traditiona1 neura1 regrowth is just l imited in nerve fiber, inc1uding axon reprojection and synapse regrowth. in fact, scientists a1ways thought that mature brain neurona1 ce11 s cou1d not regenerate when the brain fu1ly deve1oped through almost the whoie twenty centure
因此,傳統意義上的神經再生只限於神經纖維再生,即神經元軸突的再生長及突觸重塑,而神經細胞在腦發育成熟停止后不能重新再生。When a neuron fires, sending an electrical signal down its axon to its tips ( presynaptic terminals ), neurotransmitters released from vesicles cross a tiny intercellular space ( the synaptic cleft ) to receptors on the surface of a recipient, or postsynaptic, neuron
神經元放電時,電性訊號沿著軸突傳至神經末梢(突觸前終端) ,造成神經傳遞物從囊泡釋放到細胞外,並通過微小的細胞間空隙(突觸間隙) ,抵達接收端,也就是突觸后神經元表面的受體。Both the fast excitatory postsyanptic postentials ( fepsps ) and fast inhibitory postsynaptic potentials ( flpsps ) elicited by the electrical stimulation of inputs to the ca1 neurons temporally overlap in the neuron

位於接受訊息端的突觸后神經元則帶有血清張力素受體,可與其相接,並啟動細胞內的生化反應,以改變神經元對其他刺激的反應能力,或是開啟或關閉基因。分享友人
