[Responses of ampullae of Lorenzini in a uniform electric field].
Analysis of discharges of a single electroreceptor in a uniform electric field resulted in the conclusion that there is a linear relationship between the potential difference on a single ampulla and relative changes in the spike frequency. The topography of the ampullar groups can be described as a system composed by electric gratings. It is supposed that the maximum of the directional diagram of a grating corresponds to the area of a maximum sensitivity of an ampular group.
