(filtered?) Evoked Compound Action Potential (ECAP) measures Explanation: I'm afraid I haven't been able to find the translation of 'filtrado' but I'm quite sure that 'ECAP measures' is right for the rest of the phrase. I'll carry on looking! The other measurement is the Evoked Compound Action Potential (ECAP) which measures the response of the nerve fibres inside the cochlea after electrical stimuli from the implant. https://www.duo.uio.no/handle/10852/53361 Electrically Evoked Compound Action Potential (ECAP). An alternative auditory evoked potential that can be used in much the same way as the EABR is the electrically evoked compound action potential (ECAP). This is a measure of the synchronized response of the auditory nerve to electrical stimulation. Rather than being measured using surface electrodes like those used to record the EABR, the ECAP typically is recorded from an intracochlear electrode. This requires specialized technology. Cochlear Corporation was the first company to develop this technology. Since the introduction of the Nucleus CI24M device in 1998, it has been possible to measure electrically evoked intracochlear potentials in all Nucleus cochlear implant users. Cochlear Corporation refers to the software and hardware used to record this response as Neural Response Telemetry (NRT). Recently Advanced Bionics has also introduced a cochlear implant with neural telemetry capabilities and is in the process of developing software to drive this system. http://www.asha.org/policy/TR2004-00041/ -------------------------------------------------- Note added at 22 hrs (2017-05-17 16:42:10 GMT) -------------------------------------------------- I've just realised that I forgot to add 'Electrically' at the beginning. The second part of my answer should be 'electrically evoked compound action potential (ECAP) measures'. -------------------------------------------------- Note added at 22 hrs (2017-05-17 16:56:22 GMT) -------------------------------------------------- Page 5 Potentials were then low-pass filtered using 4th order Bessel filters (3 dB cut-off frequency of 15 kHz) and sampled at 25,000 sample/s/channel. https://www.healthcare.uiowa.edu/otolaryngology/auditorylab/... Page 6 As in previous experiments, auditory nerve responses were recorded using a ball electrode positioned on the auditory nerve trunk. The evoked potentials were amplified (gain=10x) and low-pass filtered at 20 kHz (6 pole Butterworth low-pass filter) prior to digital sampling at a rate of 50 kHz for subsequent analysis. https://www.healthcare.uiowa.edu/otolaryngology/auditorylab/... |
