TL;DR: This temporal resolution of 25 frames per second and spatial resolution of about 0.8 cm at about 1m and correspondingly 8 cm at 10 m distance seems sufficient for useful object recognition and visuo-motor behavior in many in- and out-door situations of daily life.

Implantation of retina stimulation electrodes and recording of electrical stimulation responses in the visual cortex of the cat
TL;DR: Intraocular implanted flat microelectrodes made of platinum and polyimide were well tolerated and higher stimulation thresholds than for needle electrodes were found, indicating insufficient con-tact to the retinal surface.

Activation zones in cat visual cortex evoked by electrical retina stimulation.
TL;DR: Effective low-power epi-retinal stimulation and intracortical recording in semichronically prepared cats is developed andarse visuomotor coordination and navigation seems possible with retina implants.

An Optically Powered Single-Channel Stimulation Implant as Test System for Chronic Biocompatibility and Biostability of Miniaturized Retinal Vision Prostheses
Thomas Schanze,L. Hesse,C. Lau,N. Greve,Werner Haberer,S. Kammer,Thomas Doerge,A. Rentzos,Thomas Stieglitz +8 more
TL;DR: A microsystem based microimplant with an optically powered single-channel stimulator was designed and developed as test system for an epi-retinal vision implant and indicated the feasibility of the system approach for chronic use.

TL;DR: The hypothesis states that the receptive field properties of visual neurons in different parts of the visual system can be linked into a perceptual whole by synchronizing the activities of those neurons that are activated by a coherent visual stimulus.
