| Abstract: | The representation of the lateral line (LL) organs in the cerebellum was studied in acute experiments on skates. It was concluded from analysis of the origin of the various components of the evoked potential (EP) that the EP to stimulation of the LL nerves consists of a fast negative—positive presynaptic wave and a slower biphasic postsynaptic response. The projection zones of each of the LL nerves coincide in the region of the auriculum and posterior lobe. The existence of two functionally different types of LL representation, exhibited as diffuse and local projections, was demonstrated. Their presence is regarded as providing a basis for the integrative activity of the cerebellar structures connected with mechanical and electrical receptors of the LL.I. P.
