AT THE BASE OF THE COCHLEA, BASILAR-MEMBRANE RESPONSES TO CHARACTERISTIC-FREQUENCY TONES GROW AT HIGHLY COMPRESSIVE RATES (e.g., 0.2 dB/dB) chinchilla guinea pig cat
COMPRESSIVE NONLINEARITY IN BASILAR-MEMBRANE RESPONSES TO CLICKS
IN SPITE OF THE PROMINENT NONLINEARITIES OF BASILAR-MEMBRANE VIBRATIONS, THE FOURIER SPECTRA OF RESPONSES TO CLICKS MATCH, LEVEL BY LEVEL, THE RESPONSES TO TONES
GROWTH OF PEAKS IN RESPONSES TO CLICKS AS A FUNCTION OF STIMULUS LEVEL
COMPRESSIVE NONLINEARITY IS PRESENT WITHIN A SINGLE PERIOD OF RESPONSE OSCILLATION
IN THE CHINCHILLA, BASILAR-MEMBRANE RESPONSES ARE MORE SHARPLY TUNED AND EXHIBIT GREATER NONLINEARITY AT THE BASE OF THE COCHLEA THAN AT THE APEX
Compression and other nonlinearities of BM responses probably arise in nonlinear transduction in outer hair cells Cooper, 2003
RESPONSES OF AUDITORY-NERVE FIBERS EXHIBIT AN INTENSITY-DEPENDENT PHASE SHIFT THAT IS NOT PRESENT IN BASILAR- MEMBRANE RESPONSES
SECOND-ORDER WIENER KERNELS OF AUDITORY-NERVE FIBERS RESPONSES TO NOISE
MAP OF DELAYS FOR THE CHINCHILLA COCHLEA
COMPARISON OF GROUP DELAYS OF BASILAR-MEMBRANE VIBRATIONS AND STIMULUS-FREQUENCY OTOACOUSTIC EMISSIONS (SFOAEs)
BASILA-MEMBRANE RESPONSES AT THE BASE OF THE COCHLEA ARE NOT MINIMUM-PHASE Original response Minimum-phase version (time domain) 44 dB SPL 104 dB SPL
BASAL RESPONSES ARE NOT MINIMUM-PHASE 44 dB SPL 104 dB SPL (frequency domain)
THE MEASURED PHASE SHIFTS AS A FUNCTION OF GAIN ARE MUCH SMALLER THAN EXPECTED FROM MINIMUM-PHASE BEHAVIOR
EVEN POST-MORTEM RESPONSES ARE NOT MINIMUM-PHASE
BASILAR-MEMBRANE RESPONSES AT THE APEX OF THE COCHLEA ARE NOT MINIMUM-PHASE
DEVELOPMENT OF BASILAR-MEMBRANE VIBRATIONS IN NEW-BORN GERBILS: RUDIMENTARY TRAVELING WAVE
POST-MORTEM BASILAR-MEMBRANE RESPONSES IN ADULT GERBIL ARE NOT MINIMUM-PHASE
BUT IN-VIVO BASILAR-MEMBRANE RESPONSES IN IMMATURE COCHLEAE ARE MINIMUM-PHASE
