摘要
In the black cicada (C. atrata Fabricius ), the quiescent males are sensitive to stimulating sound pulses of about 70 dB (SPL); the latent periods and amplitudes of compound action potentials of the auditory nerve ( called"auditory nerve potential (AP)" for short) which are corresponding one by one to stimulating sound pulses are (3 92±0 28) ms and (0 32±0 22) mV on an average, respectively. Although the singing males are nonreactive to outside stimulating sound_pulses, they are still sensitive to calling pulses mingling in stimulating sound_pulses; the latent periods and amplitudes of auditory nerve potentials are (4 16±0 43) ms and (0 46±0 25) mV, respectively. In singing males the negative potential before each auditory nerve potential characterizes that the intrinsic link exists between sounding and auditory nerve system.
