TL;DR: This paper used ultra-high-density microelectrode arrays and a rare opportunity to perform intracranial recordings across multiple cortical areas in human participants to discover three distinct classes of cortical activity that are not locked to ongoing natural brain rhythmic activity.

Temporal response properties of retinal ganglion cells in rd1 mice evoked by amplitude-modulated electrical pulse trains.
TL;DR: The results suggest that pulse amplitude modulation is a feasible means of implementing a stimulation strategy for retinal prostheses, despite the marked change in the physiological properties of RGCs in degenerated retinas.

Response of Mouse Visual Cortical Neurons to Electric Stimulation of the Retina.
TL;DR: By examining the responses of single cells, this work was able to show that some retinal stimulation strategies can indeed better match the neural signaling patterns used by the healthy visual system.
Electrically-evoked Neural Activities of rd1 Mice Retinal Ganglion Cells by Repetitive Pulse Stimulation.
TL;DR: The results suggest that the evoked neural activities of RGCs in degenerated retina can be reliably controlled by pulse frequency modulation, and may be used as a stimulation strategy for visual neural prosthesis.

TL;DR: Improved focality with magnetic stimulation suggests that the effectiveness of cortical stimulation can be improved, particularly attractive for cortical prostheses that require high spatial resolution, e.g. devices that target sensory cortex.
