Redau viziunea orbilor Este cert ca se fac progrese in acest domeniu. Nu mai demult decat alaltaieri a aparut, ahead of print, un articol valoros in PNAS.
Rezumat: Retinal prosthetics offer hope for patients with retinal degenerative diseases. There are 20—25 million people worldwide who are blind or facing blindness due to these diseases, and they have few treatment options.
Drug therapies are able to help a small fraction of the population, but for the vast majority, their best hope is through prosthetic devices [reviewed in Chader et redau viziunea orbilor.
Current prosthetics, however, are still very limited in the vision that they provide: for example, they allow for perception of spots of light and high-contrast redau viziunea orbilor, but not natural images.
Using the mouse as a model system, we generated a prosthetic system that incorporates the code. Furthermore, the results show, using 9, optogenetically stimulated ganglion cell responses, that the combined effect of using the code and high-resolution stimulation is able to bring prosthetic cilindru miopie into the realm of normal image representation.
