AUDITORY FRACTAL RANDOM SIGNALS - EXPERIMENTAL-DATA AND CLINICAL-APPLICATION

In the mammalian primary cochlear afferents, fractals in the postsynap tic bursting behaviour triggered by a constant perisynaptic release of glutamatergic transmitter agonists have been demonstrated. In order t o test the validity of fractally coded auditory signal transmission in man, frequency, intensity and temporal resolution tests were performe d in cochlear implanted patients. All patients clearly recognized the fractally coded signals transmitted to the cochlear implants. These fi rst results demonstrate evidence for fractally coded auditory signal t ransmission in man.
