Over the past two decades, neurophysiological responses in the lateral intraparietal area (LIP) have received extensive study for insight into decision making. In a parallel manner, inferred cognitive processes have enriched interpretations of LIP activity. Because of this bidirectional interplay between physiology and cognition, LIP has served as fertile ground for developing quantitative models that link neural activity with decision making. These models stand as some of the most important frameworks for linking brain and mind, and they are now mature enough to be evaluated in finer detail and integrated with other lines of investigation of LIP function. Here, we focus on the relationship between LIP responses and known sensory and motor events in perceptual decision-making tasks, as assessed by correlative and causal methods. The resulting sensorimotor-focused approach offers an account of LIP activity as a multiplexed amalgam of sensory, cognitive, and motor-related activity, with a complex and often indirect relationship to decision processes. Our data-driven focus on multiplexing (and de-multiplexing) of various response components can complement decision-focused models and provides more detailed insight into how neural signals might relate to cognitive processes such as decision making.

腹膜外侧区在决策研究中的作用

在过去的二十年中,顶叶外侧区域(LIP)的神经生理反应已得到广泛研究,以深入了解决策制定。以类似的方式,推断的认知过程丰富了对LIP活动的解释。由于生理学和认知之间的双向相互作用,LIP为开发将神经活动与决策联系起来的定量模型提供了沃土。这些模型是连接大脑和思想的一些最重要的框架,现在已经足够成熟,可以进行更详细的评估,并且可以与LIP功能的其他研究领域相结合。在这里,我们重点研究通过相关和因果方法评估的LIP响应与知觉决策任务中已知的感觉和运动事件之间的关系。由此产生的以感觉运动为重点的方法提供了LIP活动的信息,该活动是感觉,认知和运动相关活动的多重混合体,与决策过程具有复杂且通常是间接的关系。我们对各种响应组件的复用(和解复用)的数据驱动的关注可以补充以决策为中心的模型,并提供有关神经信号如何与认知过程(如决策)相关的更详细的见解。
