简介:摘要在Helicoverpaarmigera的中央神经原的短暂的外面的钾水流上的cyhalothrin的效果被使用补丁学习夹钳技术。结果在使用cyhalothrin前显示出那(10?5mmol/L),激活潜力是近似-40mV在这药的申请以后,激活潜力粗略地转移了10mV到否定潜在的方向,隧道能因此更容易被激活。在cyhalothrin申请前后,当前的振幅的变化是不足道的。V1/2的价值和然而,inactivation的V1/2弄弯的曲线没显著地改变的激活的k显著地变化了。Inactivation曲线显著地变了到一个否定方向,以便隧道的inactivation被赶快。可以在那里退出cyhalothrin通过激活潜力的规定和IA隧道的inactivation状态在提供neurotoxicity给神经系统的一个主要方法,这被显示。
