This review presents the current knowledge of the usage of critical flicker fusion frequency (CFF) in human and animal model studies. CFF has a wide application in different fields, especially as an indicator of cortical arousal and visual processing. In medicine, CFF may be helpful for diagnostic purposes, for example in epilepsy or minimal hepatic encephalopathy. Given the environmental studies and a limited number of other methods, it is applicable in diving and hyperbaric medicine. Current research also shows the relationship between CFF and other electrophysiological methods, such as electroencephalography. The human eye can detect flicker at 50-90 Hz but reports are showing the possibility to distinguish between steady and modulated light up to 500 Hz. Future research with the use of CFF is needed to better understand its utility and application.
这篇综述介绍了临界闪烁融合频率（CFF）在人类和动物模型研究中的应用现状。CFF 在许多领域都有广泛的应用，特别是作为大脑皮层唤醒和视觉处理的指标。在医学领域，CFF 可能有助于诊断，例如在癫痫或轻微肝性脑病中。鉴于环境研究和其他方法的局限性，它也适用于潜水和高压医学。目前的研究还表明 CFF 与其他电生理方法（如脑电图）之间存在关系。人类的眼睛可以检测到 50-90 Hz 的闪烁，但有报道称可以区分稳定和调制的光，频率高达 500 Hz。未来需要使用 CFF 进行更多的研究，以更好地了解其效用和应用。
