The details of the morphology of the nervous system has been investigated in two turbellarian species Polycelis tenuis and Girardia tigrina using confocal laser scanning microscopy and immunostaining to neuropeptide FMRFamide. Abundant FMRFamide immunoreactivity (FMRF-IR) has been observed in central and peripheral nervous systems of both species. Intensive staining has been found in the sensory elements: cells and fibres surrounded the mouth opening, in the fibres enclosed the photoreceptors, triangular auricles in the head region of G. tigrina. The possible function of FMRF-IR neurons in the realization of sensory function in turbellarians is discussed.
利用共聚焦激光扫描显微镜和对神经肽FMRF酰胺进行免疫染色的方法，对两种涡虫（细身多盘涡虫和虎斑涡虫）神经系统的形态细节进行了研究。在这两种涡虫的中枢和外周神经系统中均观察到丰富的FMRF酰胺免疫反应性（FMRF-IR）。在感觉元件中发现了强烈的染色：围绕口部开口的细胞和纤维、包围光感受器的纤维、虎斑涡虫头部区域的三角形耳叶。本文讨论了FMRF-IR神经元在涡虫感觉功能实现中的可能作用。
