Abstract

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.
