en Experimental research article Experimental research article <p>  Electrocochleography (ECoG) records the electrophysiologic activity of the most peripheral part of the auditory system, the inner ear cochlea and the 8^th nerve. Auditory evoked potentials being recorded are Cochlear Microphonic (CM) and Summating Potential (AP). In order to provide the proper background for laboratory research and introducing an ECoG curve of a model animal, it was decided to record the ECoG from rabbit. Rabbits of either sex weighting about 2 kg (n=25) were experimented upon. Evoked auditory potentials to clicks of 75 and 85 dB were analyzed off-line and compared with human data obtained from a clinical audiometry laboratory. The results are as followed: -SP/AP amplitude and latency showed no significant difference in either intensities, in rabbit. -SP and AP amplitude and latency were significantly greater in rabbit. -The ratio of SP/AP amplitude and latency in rabbit and human indicated no differences. -AP amplitude in 75 dB intensity was greater in the right ear compared with the left (p ≤0.05) however, in other cases, amplitude of waves was greater in the left ear (p ≤0.05). </p> Electrocochleography; Evoked auditory potentials; Rabbits 32 37 http://ppj.phypha.ir/browse.php?a_code=A-10-110-58&slc_lang=en&sid=1
