So far few studies have examined the ontogeny of the overall synaptic responses in rat hippocampal ca1 neurons during postnatal development a systematical study of the evoked synaptic responses during development is useful for understanding the developmental integration of neural signals on the ca1 pyramidal neurons
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。Tiny membranous bubbles called vesicles erupt from each signal - sending, or presynaptic, neuron, releasing serotonin into the synapse
位於訊息發送端的突觸前神經元末梢,帶有微小的膜狀囊泡包裹著血清張力素,可將其釋放到突觸中。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。Prozac and similar antidepressant drugs work by binding to serotonin transporters and preventing presynaptic neurons from soaking up the secreted serotonin too quickly, allowing it to linger a bit longer in the synapse and continue to transmit its soothing effect
百憂解及類似抗抑鬱藥的作用,就是與血清張力素轉運子相接,防止突觸前神經元太快將釋出的血清張力素重新吸收回去,使得血清張力素在突觸間停留的時間更長一些,持續傳遞其安定人心的效用。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。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。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。分享友人
