“…Experimental evidence of these highly restricted representations using the radial bipolar configuration in cats has been reported ͑van den Honert and Stypulkowski, 1987;Snyder et al, 1990͒. Although the radial bipolar configuration generated some very narrow STCs in some animals in this study the mean selectivity was greatest for the offset radial configuration. The trend to broader representation with increased interelectrode spacing, seen in limited numbers of animals studied in previous experiments ͑Merzenich et al., 1979;Snyder et al, 1990͒, was also observed in all animal groups in this study. However, this difference was statistically significant in only the neonatally deafened animals studied at less than 1.5 years of age.…”

“…As noted earlier, an obvious difference in electrically-evoked inferior colliculus (IC) vs acoustically-evoked IC responses was evident in temporally evoked patterns of activity (Merzenich et al, 1974a;Merzenich, 1975;Merzenich et al, 1979;Merzenich, 1983a;White, 1984). Electrical stimuli evoked more-simultaneous nerve array excitation.…”

“…In our earliest studies, we assumed that multichannel cochlear implants were most likely to be implemented in one of two forms (Merzenich, 1975;Merzenich et al, 1977;Merzenich et al, 1979;Merzenich et al, 1980a). A first model form would simulate, as faithfully as possible, the normal distributed patterns of auditory nerve inputs delivered from the inner ear to the brainstem, achieved via patterned multi-site electrical stimulation.…”

“…The results showed that with bipolar stimulation from electrodes on a mold of the scala tympani, the current could be localized to separate groups of nerve fibers . The current distribution for bipolar stimulation, however, varied depending on the orientation of the electrode pair and the presence or absence of peripheral processes (dendrites) of spiral ganglion cells (Merzenich et al 1979).…”
