shows the mean±S.D. of the auditory brainstem responses at .5 (3A1) −32 (3A8) kHz tones were recorded up to 30 days following cochlear implant surgery (at day 0) in rats. The responses were compared for three groups: normothermic cochleae receiving EIT (red, n=7 except for days 14, where n=5 and 28, where n=6), hypothermic cochleae receiving EIT (blue, n=7 except for days 14, where n=5 and 28, where n=6) and non-operated, contralateral control cochleae (black, n=14 except for days 14, where n=10 and 28, where n=12). The electrode was chronically implanted and remained in place throughout the duration. 3B) shows the results represented as mean±S.D. of the threshold shift on days 1, 3, 7, 14 and 28 following electrode insertion from intranimal pre-surgical thresholds.
