[Bradykinin as a factor regulating synaptic inflow to the neurons in Helix pomata].

The action of bradykinin on spontaneous electric activity of Helix pomata neurones from the subfaringeal complex was studied by microionophoresis. Bradykinin not only facilitates the neuronal responses to synaptic activation, but also prolongs the activation-induced generation of the potential action. Bradykinin effects were observed only in experiments conducted in spring.
