General / Off-Topic Bionic eyes and applications

It's unclear how far off we are from getting artificial vision. What is clear is that changing the input is going to transform how and what we can see.



If there's a wireless feed directly to the retina, it does not have to come from the optical camera in the eyesocket. It does not even have to be live feed from the real world, from a remote camera.

It can contain whatever augmented information we wish to add. It can be a heat map in the dark, a sonic map built from a sonar tranciever underwater, an image of UV radiance, of radio waves, a movie, your internet feed, or whatever the Matrix/Metaverse wants you to see, or NOT see.

The potential for Totalitarianism continues to grow.

If we manage to decode the peripheral nerve transmission signal, this can migrate to a ring implant round the optic nerve, something that could be relatively easily installed in healthy eyed people, to augment, replace or hijack the normal signal.

Current understanding of what content nerve signals are actually composed of and their effects are on the recieving brain is shockingly limited and incomplete. We thought vagus nerves carried some just gut feedback. We were wrong.

Vagus nerve stimulation is used to treat epilepsy now, and here are the results from a Parkinson's disease trial:

Significant improvements in key gait parameters were observed with nVNS, including walking speed, stance time and step length, compared to sham. Similarly, overall motor function (MDS-UPDRS III) also improved significantly following nVNS stimulation. Serum Tumor Necrosis Factor (TNF)-α and glutathione levels decreased and brain-derived neurotrophic factor (BDNF) levels increased significantly (p < 0.05) after treatment with nVNS.
Change the nerve signal code, change brain chemistry, walking, and alter siezure thresholds.

Are optic nerves ONLY carrying a visual signal? Probably not. Flashing lights start fits. Visual input changes mood.
I guess we will be finding out.
