细胞外记录 meaning in English
extracellular recording
Examples
- The stimulus selectivity and pattern adaptation of neurons in the primary visual cortex ( area 17 ) of young adult and old cats was , for the first time , comparatively examined using single - neuron in vivo recording techniques
本文采用电生理和形态学手段对老年猫初级视皮层神经元的功能衰退进行观察并对其潜在的神经机制作了初步探讨。 1 .运用在位细胞外记录方法比较研究视皮层v1区细胞的刺激选择和图形适应特性。 - Electrophysiological experiment : in 73 rats , extracellular recordings in vivo were made from pvn using 3 - barrel microelectrode . neurons were categorized as gastric distension excitatory ( gd - e ) or inhibitory ( gd - i ) neurons tested with gastric distension stimulus . drugs were applied through the 3 - barrel microelectrode by a 4 - programmable pressure injector ( pm2000b , mdi , usa ) : relin , saline ( control group ) relin , " [ d - lys - 3 ] - ghrp - 6 ( antagonist for ghrelin - r ) , to observe the effects of drugs on the neuron discharge
电生理实验方法：在73只大鼠中，应用三管玻璃微电极细胞外记录麻醉大鼠一侧pvn神经元自发放电，用水囊充盈胃鉴别胃扩张敏感神经元( gdsn ) ，以压力注射仪( pm2000b ， mdi ， usa )经三管玻璃微电极，对核团内中文摘要单个神经元分别微量注射给予: ghrelin 、生理盐水ns (对照) ghrelin 、 d一lys一3 ]一ghrp一6 ( ghrelin受体拮抗剂) ，观察药物对神经元单位放电的影响。 - Abstract : in order to clarify the location of the center for synchronized milk - ejection bursts of magnocellular oxytocin neurons in the hypothalamus , the bursts of these neurons were recorded extracellularly in lactating rats with selectively - cutting lesions of the middle brain or hypothalamus
文摘:为探究授乳大鼠双侧下丘脑巨细胞催产素神经元同步化射乳反射爆发放电的中枢所在,我们采用双微电极细胞外记录技术,观察了选择性脑切割损毁后的大鼠双侧视上核内催产素神经元在仔鼠吸吮刺激下射乳反射爆发放电。 - Using this system , we have studied matrine - inhibittory effect and trifluoperation - neuroprotection effect in hippocampal slices , also discussed the mechanism of long - term potentiation using anesthetic rats . the experiment results showed that matrine can inhibit the hyperactivity induced by penicillin sodium in dosage by changing the relative parameters of field potential ; trifluoperation can alter ps change with the time , enhance the degree and the ratio of ps recovery , then minis the hypoxic injury ; high frequency stimulate can increase ps amplitude and epsp slope for long time , buildup the in / out function of nerve cells , and enhance synaptic plasticity
结果表明，苦参碱能够剂量依赖性地抑制青霉素诱导的神经元顺向信号传导激活过程，使细胞外记录到的场电位各个参数发生相应改变；三氟拉嗪可以改变ps的时相变化，提高ps的恢复程度和恢复率，减小了神经元因缺氧引起的不可逆损伤；高频刺激( highfrequencystimulate ， hfs )可以长时间的增强ps的幅度和epsp的斜率，进而增强神经元的输入输出功能，增加了突触的可塑性。
