Design outcomes

Primary

Measure	Time frame
The main study parameters are ECoG recordings, and specifically their amplitudes that will be compared before, during and after surgery. These measures can be correlated to the standard subjective clinical measures (pure tone audiograms) after surgery.	—

Secondary

Measure	Time frame
Benchmark recordings of the ECoG during surgery using standard (high-quality) BERA equipment. Similarly, eCAP recordings will be benchmarked against the normal standard-of care eCAP recordings obtained via the implant electronics. eCAPs will be analyzed through standard methods, including amplitude-growth functions and threshold measurements.	—
