胚胎斑马鱼是一个很好的研究模型,可以用来研究协调运动行为的神经网络。它在发育早期表现出强大的运动行为,与哺乳动物系统相比,它的神经系统相对简单且容易接近,并且存在具有特定分子和运动缺陷的突变体。我们已经开发了一系列的四个练习,为学生提供运动行为发展,神经系统组织,神经递质反应性的发展和遗传学的基本理解。前两个练习可以在一个3小时的实验室周期内进行,第三和第四个练习,建立在前两个练习的基础上,可以在一个或两个后续周期内完成。在第一个练习中,学生观察和量化两个不同的行为,表征不同的发展阶段,自发运动,和触摸诱发的尾巴卷曲。在第二个实验中,学生们使用药理学方法来确定神经递质甘氨酸是否是胚胎执行每一种行为所必需的。在第三种情况下,他们使用简单的损伤来评估每种行为是否需要大脑。在第四个实验中,学生们通过观察自发运动和触摸诱发的尾巴卷曲、进行损伤和应用药理学药物期间的行为,检查了一种具有甘氨酸受体缺陷的斑马鱼运动突变体bandoneon。这些练习很容易适应,因此可以省略或扩展部分以检查其他神经递质系统或运动行为发展的后期阶段。
The embryonic zebrafish is an excellent research model to examine the neural networks that coordinate locomotive behavior. It demonstrates robust locomotive behavior early in development, its nervous system is relatively simple and accessible compared to mammalian systems, and there are mutants available with specific molecular and motor deficits. We have developed a series of four exercises that provide students with a basic understanding of locomotive behavior development, nervous system organization, development of neurotransmitter responsiveness, and genetics. The first two exercises can be performed in one 3-h laboratory period, and the third and fourth exercises, which build on the first two, can be completed in one or two subsequent periods. In the first exercise, students observe and quantify two distinct behaviors that characterize different developmental stages, spontaneous movement, and touch-evoked tail coiling. In the second, the students use a pharmacological approach to determine if the neurotransmitter glycine is required for the embryo to perform each behavior. In the third, they use simple lesions to assess whether the brain is required for each type of behavior. In the fourth, the students examinebandoneon, a zebrafish motility mutant that has a glycine receptor defect, by observing its behavior during spontaneous movement and touch-evoked tail coiling, performing lesions, and applying pharmacological drugs. These exercises are readily adaptable, such that portions can be omitted or expanded to examine other neurotransmitter systems or later stages of locomotive behavior development.
