该视频演示了如何从果蝇幼虫三龄中枢神经系统解剖。解剖后,中枢神经系统,可染色,使用一个标准的免疫组织化学协议。目前,很多仍然是未知的成年神经系统是如何产生以及如何存储和传输信息。发展中国家的果蝇幼虫中枢神经系统的研究应该加强我们的神经系统的布线和功能知识。
果蝇幼虫stereotpyed的行为,如环境因素的反应,表现出。如何教训和神经系统中存储的这些行为呢?幼虫发育期间的神经系统的研究将有助于回答这个问题。
此时在果蝇发育阶段,机体准备接受广大化蛹期间发生的形态学变化。在这段时间内发生大规模的重塑,神经肌肉系统从爬行蛆到成年飞organsim转换。这将是有趣,以确定神经元的变化如何在这个发展阶段,如果同一类型的行为,可以在高等动物的神经元观察。
