Our continuous perception of the world could be the result of discrete sampling, where individual snapshots are seamlessly fused into a coherent stream. It has been argued that endogenous oscillatory brain activity could provide the functional substrate of cortical rhythmic sampling. A new study demonstrates that cortical rhythmic sampling is tightly linked to the oculomotor system, thus providing a novel perspective on the neural network underlying top-down guided visual perception.
我们对世界的持续感知可能是离散采样的结果,即各个瞬间被无缝融合成一个连贯的信息流。有人认为,内源性振荡脑活动可为皮层节律性采样提供功能基础。一项新研究表明,皮层节律性采样与动眼系统紧密相连,从而为自上而下引导的视觉感知背后的神经网络提供了新视角。
