Vision plays a major role in perceiving external stimuli and information in our daily lives. The neural mechanism of color vision is complicated, involving the co-ordinated functions of a variety of cells, such as retinal cells and lateral geniculate nucleus cells, as well as multiple levels of the visual cortex. In this work, we reviewed the history of experimental and theoretical studies on this issue, from the fundamental functions of the individual cells of the visual system to the coding in the transmission of neural signals and sophisticated brain processes at different levels. We discuss various hypotheses, models, and theories related to the color vision mechanism and present some suggestions for developing novel implanted devices that may help restore color vision in visually impaired people or introduce artificial color vision to those who need it.
视觉在我们日常生活中感知外部刺激和信息方面起着重要作用。色觉的神经机制很复杂，涉及多种细胞的协同功能，如视网膜细胞和外侧膝状体细胞核细胞，以及视觉皮层的多个层次。在这项工作中，我们回顾了关于这个问题的实验和理论研究的历史，从视觉系统单个细胞的基本功能到神经信号传递中的编码以及不同层次复杂的大脑过程。我们讨论了与色觉机制相关的各种假设、模型和理论，并提出了一些关于开发新型植入设备的建议，这些设备可能有助于恢复视力受损者的色觉或为有需要的人引入人工色觉。
