[Correlation of the electrical and mechanical resonance frequencies of the cochlear hair cells of the auditory nerve fibers in the pigeon].

Base period (BP) of the quasi-periodical spontaneous activity and characteristic frequency (CF) were determined in 67 auditory fibres of pigeon: BP.CF = 1.02 +/- 0.08 (c.f. 10, 11). This evidences for the coincidence between the frequencies of electrical and mechanical resonances of hair cell. Active electric resonance in the cell membrane is evoked by the positive feedback between mechanoelectric and electromechanical transduction in the cochlear hair cell.
