6. Evaluation of the method of inactivation of the cricket cercal sensilla by means of electrocercogramm

A new method of registration of electrical activity of isolated cercus, the electrocercogramm, was proposed. Waveform reaction to air puff consists of fast transient negative on-response, followed by sustained plato, and transient off- response on the stimulus termination. Cercus inactivation by applying glycerol layer onto its surface was employed before in behavioral experiments. Glycerol inactivation of isolated cercus reduces amplitudes of on- and off-responses by factor of 2–3, the plato value falled below the noise level for the majority of preparations.

Key words: electrocercogram, mechanoreception, cercus
