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.
调节电兴奋细胞活性的方法和组合物。光电化合物,在光能照射下可增加或减少细胞的电活动。这些化合物可补充和/或替代视觉系统中某些细胞将光能转化为电能的过程。这种 "补丁 "或桥梁可避免视觉系统中一个或多个有缺陷、受损或患病的细胞。此外,在一些实施方案中,视力正常的受试者也能从本文公开的方法、组合物、系统和/或设备中获益,因为正常视力的敏锐度可以提高。曝光诱导一种能量(例如,接收光能、转换为电能和通过该电能)从光电化合物到细胞,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。
