Extracellular recordings of cockroach nervous system bioelectrical activity. (a) An example of recordings of the cercal nerve activity as a response to cercus mechanostimulation (marked by black arrow); 1 – recording of a spontaneous activity, 2 – recording of a response to mechanostimulation, 3 – recording of the activity after stimulation. (b) An example of corresponding recordings from the connective nerve with the same value of stimulus as in a. (c) An example of recordings of the connective nerve response to a larger stimulus
