How does the integrated and unified conscious experience arise from the vastly distributed activities of the nervous system? How is the information from the many cones of the retina bound with information coming from the cochlea to create the association of sounds with objects in visual space? In this perspective article, we assert a novel viewpoint on the "binding problem" in which we explain a metastable operation of the brain and body that may provide insight into this problem. In our view which is a component of the Default Space Theory (DST), consciousness arises from a metastable synchronization of local computations into a global coherence by a framework of widespread slow and ultraslow oscillations coordinated by the thalamus. We reinforce a notion shared by some consciousness researchers such as Revonsuo and the Fingelkurts that a spatiotemporal matrix is the foundation of phenomenological experience and that this phenomenology is directly tied to bioelectric operations of the nervous system. Through the oscillatory binding system we describe, cognitive neuroscientists may be able to more accurately correlate bioelectric activity of the brain and body with the phenomenology of human experience.
整合统一的意识体验是如何从神经系统广泛分布的活动中产生的？视网膜上众多视锥细胞的信息是如何与来自耳蜗的信息结合起来，从而在视觉空间中建立声音与物体的关联的？在这篇观点文章中，我们对“捆绑问题”提出了一种新颖的观点，在其中我们解释了大脑和身体的一种亚稳态运作，这可能为该问题提供见解。在我们作为默认空间理论（DST）一部分的观点中，意识源于局部计算通过丘脑协调的广泛的慢振荡和超慢振荡框架，亚稳态同步为全局连贯性。我们强化了一些意识研究者（如雷冯苏奥和芬格尔库茨）所共有的一个观念，即时空矩阵是现象学体验的基础，并且这种现象学与神经系统的生物电运作直接相关。通过我们所描述的振荡捆绑系统，认知神经科学家或许能够更准确地将大脑和身体的生物电活动与人类体验的现象学联系起来。
