设计、测试和部署控制论接口到人类大脑视觉区域的可能性激发了科学家、生物医学工程师、临床医生和科幻作家的灵感。作为皮质视觉假体,视觉知觉可能提供给失明个体。基于20世纪60年代后期的开创性工作,以及20世纪剩余时间内重要技术的发展,皮质内视觉假体(ICVP)正在计划进行临床试验。自主的,无线的,16通道的刺激器模块将用于平铺人类枕叶的背外侧表面。每个模块将包含16个皮质内电极,穿透皮质表面,为大脑的视觉处理区域提供模拟电流。通过使用时空整合,期望大脑将人工的视觉信息转化为有用的视觉感知。虽然ICVP不能产生正常的视觉,但之前的工作强烈表明,人工视觉感知可能会显著提高用户识别物体和导航的能力,并提高整体生活质量。
The possibility of engineering, testing, and deploying a cybernetic interface to the visual areas of the human brain has inspired scientists, biomedical engineers, clinicians, and science fiction writers. Implemented as a cortical visual prosthesis, visual perception might be provided to individuals with blindness. Based upon pioneering work in the late 1960’s, and the development of significant technology throughout the remainder of the twentieth century, the Intracortical Visual Prosthesis (ICVP) is being planned for clinical trial. Autonomous, wireless, 16-channel stimulator modules will be used to tile the dorsolateral surface of the human occipital lobe. Each module will contain 16 intracortical electrodes that penetrate the cortical surface and provide simulation currents to visual processing areas of the brain. Through the use of spatial and temporal integration, the expectation is that the brain will convert the artificial visual information into useful visual perceptions. While it is not expected that the ICVP will produce normal vision, prior work strongly suggests that the artificial visual perception may notably enhance the user’s ability to recognize objects and navigate, and improve overall quality of life.
