Abstract: The present disclosure provides devices, systems, and methods for spinal cord stimulation. In some exemplary embodiments, a lead is provided. In one exemplary embodiment, the lead includes a paddle and an electrode array distributed in the paddle. The electrode array includes a first column of electrodes and a second column of electrodes. The first column of electrodes and the second column of electrodes are symmetric about the midline of the paddle. The first column of electrodes includes a first electrode, a second electrode, and a third electrode. The second column of electrodes includes a fourth electrode corresponding to the first electrode, a fifth electrode corresponding to the second electrode, and a sixth electrode corresponding to the third electrode. A vertical inter-electrode distance between the first electrode and the second electrode is larger than that between the second electrode and the third electrode.

Abstract: An input signal (f) representative of a scene to be viewed comprises, for each pixel of a matrix of pixels, an event-based asynchronous-signal sequence obtained as a function of variations of light relating to the pixel in the scene. This input signal is transformed spatially within the matrix of pixels and temporally along the signal sequences to generate respective control signals (S) for pixel zones of a device for aiding vision (20).

Abstract: The invention relates to an implant which includes, in order to electrically stimulate a nerve structure, in particular the retina, an electrically insulating substrate (1), a array of recesses (2) formed in an upper surface of the substrate, stimulation electrodes (3) arranged at the bottom of the recesses, and an electrically conductive layer forming a ground plane (4) at the upper portion of the recesses. The sizes of the recesses and of the electrodes of the implant are such that the spatial selectivity of the stimulation current applied to the nerve structure is maximized.
