Methods and compositions modulate the activity of electrically excitable cells. Photovoltaic compounds which, upon exposure to light energy, increase or decrease the electrical activity of cells. These supplement and/or replace of vision based on the conversion of light energy to electrical energy within certain cells of the visual system. A "patch" or bridge to circumvent one or more defective, damaged, or diseased cells in the visual system. Additionally, in several embodiments, subjects with normal vision can benefit from the methods, compositions, systems, and/or devices disclosed herein as normal visual acuity can be heightened. The exposure induces an energy (e.g., a receipt of light energy, conversion to electrical energy, and passage of that electrical energy) from the photovoltaic compound to the cell, thereby altering the transmembrane potential of the cell and/or the opening of one or more ion channels, thereby modulating the activity of the electrically excitable cell.
方法和配方调节电兴奋细胞的活动。光电池化合物,在受到光能照射时,增加或减少细胞电活动。这些补充和/或替代基于将光能转化为视觉系统内某些细胞的电能的视觉。一种“贴片”或桥梁,用以绕过视觉系统中的一个或多个缺陷、损坏或病变细胞。此外,在多种实施方式中,正常视力的受试者也可以从本公开的方法、配方、系统或设备中受益,因为正常视力可以增强。照射引发能量(例如,接收光能,转化为电能,并传递该电能)从光电池化合物到细胞,从而改变细胞的跨膜电位和/或打开一个或多个离子通道,从而调节电兴奋细胞的活动。
