【摘要】 用玻璃微电极引导出中华按蚊正常ERG为双相电位,有三种主要成分:正相(向下偏曲)给反应、负相撤反应和两者间的正相持续性慢电位;视叶内电位极性与ERo相反。在电极插入过程中,电位有二次反极。实验表明,刺激光强度、背景明暗状态及乙醚、窒息等对其光电反应均有明显的影响。更多还原

【Abstract】 This paper reports the results of the study on the gross electrical response of the visual system of An.sinensis with micropipette electrode.The normal electroretinogram (ERG) of An.sinensis is diphasic, including three main components, i.e.the positive (deflected downwards) on-effect, the negative off-effect and the positive slow sustained wave.The phase of the response in the optic lobe is opposite to ERG.From the tissues outside the optic lobe into the optic lobe and compound eye, the phase of wave changes twice.It shows that the strength of stimulation, light and dark adaptation condition, and the effect of ether and suffocation may affect the response of the visual system of the mosquito.更多还原
