[Abstract]  

Muscimol is a psychoactive isoxazole derived from the mushroom Amanita muscaria. As a potent GABAA receptor agonist, muscimol suppresses the activity of the central nervous system, reduces anxiety and induces sleep. We investigated the effects of muscimol on Drosophila behavior. Drosophila behavioral assays are powerful tools that are used to assess neural functions by focusing on specific changes in selected behavior, with the hypothesis that this behavioral change is due to alteration of the underlying neural function of interest. In this study, we developed a comparatively simple and cost-effective method for feeding adult flies muscimol, a pharmacologically active compound, and for quantifying the phenotypes of “resting” and “grooming+walking”. This protocol

[摘要]  [摘要] Muscimol是一种精神活性的异恶唑,衍生自蘑菇鹅膏菌(Amanita muscaria)。作为有效的GABA A受体激动剂,muscimol抑制中枢神经系统的活动,减轻焦虑并诱导睡眠。我们调查了麝香酚对果蝇行为的影响。果蝇行为分析小号是强大的工具,小号是用来评估通过着眼于选择行为的具体变化,与假设,这种行为的改变是由于利益的根本神经功能改变神经功能。在这项研究中, 我们开发了一种相对简单且经济高效的方法来喂养成年蝇麝香酚(一种药理活性化合物),并定量“休息”和“修饰+行走”的表型。该协议可以为研究人员提供一种便捷的方法来表征苍蝇中小分子诱导的行为输出。


[背景]越来越多的证据小分子可用于神经元病症的治疗(Rissman和莫布里,2011) 。因此,知识的小分子诱导行为的神经生物学人的变化和阐发IR底层机制将促进我们的理解的神经回路的功能机制。但是,大多数以前的行为研究都以小鼠或大鼠为模型,完成此类研究需要大量资源。果蝇已被用作研究许多遗传疾病的易处理的遗传模型(Mackay和Anholt,2006),近年来,它们被用作行为研究的模型变得越来越普遍(Zhukovskaya等,2013; Chen等。,2014; Hampel等人,2015; Kaur等人,2015; Pitmon等人,2016; Hidalgo等人,2017)。 ...
