Abstract:
The cochlear microphonic measured in scala tympani referenced to that at the round window is used to determine characteristic frequency (CF) at two locations in an age-graded series of Mongolian gerbils. No significant ontogenic shift in CF is seen at a second turn location, while an approximately 1.5 octave shift is seen in the mid-basal turn.
