我们设计了一个实时计算机视觉系统,多蠕虫跟踪器(MWT),可以同时量化的行为,几十个秀丽隐杆线虫在传统的培养皿上的视频速率。三个传统的行为范式使用这个系统进行检查:食物上的自发运动,其中的行为在几十分钟内发生变化;趋化性,其中必须准确地检测到转折事件,以确定策略;和习惯化的响应自来水,其中的响应是随机的,并随着时间的推移而变化。在每种情况下,手动分析或自动化的单蠕虫跟踪都是繁琐和耗时的,但MWT系统允许以最少的人力快速量化行为。因此,该系统将能够对复杂行为进行大规模正向和反向遗传筛查。
We have designed a real-time computer vision system, the Multi-Worm Tracker (MWT), that can simultaneously quantify the behavior of dozens of Caenorhabditis elegans on a traditional petri plate at video rates. Three traditional behavioral paradigms are examined using this system: spontaneous movement on food, where the behavior changes over tens of minutes; chemotaxis, where turning events must be detected accurately to determine strategy; and habituation of response to tap, where the response is stochastic and changes over time. In each case, manual analysis or automated single-worm tracking would be tedious and time-consuming, but the MWT system allows rapid quantification of behavior with minimal human effort. Thus, this system will enablelarge scale forward and reverse genetic screens for complex behaviors.
