The primate brain codes perceived events in a distributed fashion, which raises the question of how the codes referring to the same event are related to each other. Recent findings suggest that they are integrated into 'object files', episodic bindings of object-related information. However, the problem of integrating distributed codes is not restricted to perception but applies to action planning and sensorimotor processing as well. Here I argue that the brain addresses these problems by creating multi-layered networks of bindings - 'event files' - that temporarily link codes of perceptual events, the current task context, and the actions performed therein. These bindings produce systematic but often surprising and counter-intuitive interactions between, and impairments in, perception and action planning.
灵长类动物的大脑以分布式方式对感知到的事件进行编码,这就引出了一个问题:指代同一事件的编码是如何相互关联的。最近的研究结果表明,它们被整合到“对象文件”中,即与对象相关信息的情景绑定。然而,整合分布式编码的问题并不局限于感知,也适用于行动规划和感觉运动处理。在这里,我认为大脑通过创建多层绑定网络——“事件文件”来解决这些问题,这些网络临时链接感知事件的编码、当前任务背景以及其中执行的动作。这些绑定在感知和行动规划之间产生了系统的但往往令人惊讶和违反直觉的相互作用及损伤。
