    Abstract:
    The structure of the Mauthner cells in Xenopus laevis tadpole was investigated by light- and electron microscopy in norm and after early unilateral enucleation. It was found that enucleation at early stages caused a delay in morphological development of the contralateral neurons during embryogenesis. We observed a decrease in size of the soma and nucleus and in the number of dendrites, a marked structural underdevelopment of the majority of cell organoids, as well as proliferation and hypertrophy of transversal cisternae in the contralateral Mauthner cells. The ipsilateral neurostructure remained normal in embryogenesis. The data obtained suggest the availability of some unknown powerful afferent contralateral input to Mauthner cells from the optical analyzer.
