解釋
邊緣細胞 在木質線中之上下邊緣之細胞于縱切面可見之-
The patch clamp experiment : the cell - attached and inside - out configurations of the patch - clamp techniques were used to investigate single channel properties of nmd a receptors in the actuely dissociated neurons of the marginal division in the rat striatum, recording the current amplitude. long / short term opening / closing times indexes and the effects of incitants and agonists of the nmd a receptors on those parameters. we find that two types of conductance of 42ps and 20ps were recorded, the 42ps was the advantaged conductance
本研究是在本實驗室以前研究的基礎上,通過膜片鉗( pachclamp )觀測sd ( sprague - dawley , sd )的mrd上nmda受體通道的電生理特性;繼而對青壯年sd大鼠的mrd 、海馬進行毀損並腹腔注射nmda受體阻滯劑ktm ( ketamine , ktm ) ,觀察其對大鼠學習記憶能力的影響:對于學習記憶能力下降的老年鼠進一步做顱內定位注射nmda受體激動劑與抑制劑,觀察其在特定部位的作用;最後,應用fmri ( functionalmagneticresonanceimaging ; fmri )對注射ktm的志願者做學習記憶與痛覺的對比觀察。
