title: [Spontaneous activity of the hair cells of the snail statocyst and changes in it as a result of intracellular stimulation].
abstract: The activity of hair cells in the stotocyst of Helix lucorum was studied by means of intracellular recording. Maximal magnitude of input resistance of hair cell membranes was observed in the range of the injected hyperpolarizing current between 0 and 0.1 nA. Voltage noise was a specific type of hair cell activity. It was independent of synaptic activity and had no pacemaker nature. The voltage noise depended only on the contact between hair cell cilia and statoconia. Hair cell depolarization enabled to reveal the pacemaker properties of the receptor membrane. Spike-triggering zone was found to be located in the axon of hair cell. IPSP recorded in the hair cells of the preparations with the static nerve cut confirmed the existence of inhibitory interactions within the statocyst.
