The oscillatory response of the electroretinogram and neuronal adaptation

open access: yesActa Ophthalmologica, Volume 104, Issue 6, Page 616-637, September 2026.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

Injectable Artificial Photoreceptors: STEM Cell Functional Integration and in vivo Electrophysiological Validation in Retinal Degeneration Models

open access: yesSmall Science, Volume 6, Issue 8, August 2026.
Artificial photoreceptors are engineered to efficiently absorb light, with the strongest sensitivity in the green region of the visible spectrum. Upon illumination, they generate electrical signals that activate retinal ganglion cells, which are typically unaffected by disease, enabling transmission of visual information to the brain.
