extracellular recording meaning in Chinese

细胞外记录

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。
