Abstract:We have studied the effect of a weak electromagnetic field on the morphogenesis of the planarian Dugesia tigrina. The regeneration of the pharynx was examined after its amputation. We have determined the rate of the appearance of the food response of a new pharynx. Experimental conditions were varied, such as dose and duration of irradiation, season, and time of irradiation after surgery. The results of experiments conducted with 2966 planarians have shown that weak electromagnetic field has various effects, which appear either as stimulation of regeneration or as its inhibition. In some experiments, there was no effect at all. These differences depend on numerous factors and may be modulated.
Keywords:planarians  regeneration  pharynx  electromagnetic field
