That is definitely the weirdest part to me. It is supposed to be a trial for this new implant right? So why isn't the company actually working with them on it? Like how is just telling someone do more therapy acceptable here? Studying their brain's reactions to the stimulus the implant is actually generating seems like something that should have already been done.

I would think you could take the audio processor out of the loop and run diagnostics on the implant itself using an EEG to determine how the brain is responding. They test the hearing of newborns with the tech, you don't need to "trust" a person or even need them to be able to communicate. Its right there in the data.

Based on my read of everything it feels like there is some issue with the implant sending electrical signals, but the nerve not actually picking them up and sending them on. Perhaps related to the original reason for the hearing loss. And the company should want to dig info it more. I know I would if it were my tech.
