Efferente Summenaktionspotentiale am Nervus cochlearis des Meerschweinchens bei kontralateraler Beschallung

After removal of the organ of Corti on one side, four sequential efferent compound action potentials were registered from the cochlear nerve of the same side upon click stimulation of the contralateral ear. For an input of 105 dB SPL, there were three early potentials having maximum average latencies of 2.3, 3.1, and 4.7 msec, and average amplitude of 60, 50, and 25 µV respectively.
