一直以来,人们都非常重视癫痫发作在认知障碍(如癫痫记忆缺陷)的病因中所起的作用。在这里,我们专注于这些赤字背后的另一种假设,强调健康认知的信息处理机制,其特征在于速率,时间和人口编码。我们讨论了癫痫的潜在病因学在改变神经网络中的作用,从而导致癫痫发作的倾向和相关的认知障碍。此外,我们提出了可以在患病大脑的背景下恢复网络功能的潜在治疗方法,从而同时改善癫痫发作和认知结果。本文综述了在网络神经科学的指导下,从系统水平的角度超越癫痫发作和接近缺陷的重要性。
There has been a major emphasis on defining the role of seizures in the causation of cognitive impairments like memory deficits in epilepsy. Here we focus on an alternative hypothesis behind these deficits, emphasizing the mechanisms of information processing underlying healthy cognition characterized as rate, temporal and population coding. We discuss the role of the underlying etiology of epilepsy in altering neural networks thereby leading to both the propensity for seizures and the associated cognitive impairments. In addition, we address potential treatments that can recover the network function in the context of a diseased brain, thereby improving both seizure and cognitive outcomes simultaneously. This review shows the importance of moving beyond seizures and approaching the deficits from a system-level perspective with the guidance of network neuroscience.
