多感知决策(MSDM)是一种在复杂环境中做出更准确和敏感决策的基本策略。虽然这一领域才刚刚兴起，但最近从不同角度的非凡工作，包括计算理论、心理物理行为和神经生理学，开始为MSDM带来新的曙光。在目前的综述中，我们通过使用视觉前庭标题的模型系统来关注MSDM。结合虚拟现实系统中控制良好的行为范式、单位记录、因果操作和基于放电活动的计算理论，最新进展表明，前庭信号在许多大脑区域包含复杂的时间动力学，包括单感觉、多感觉和感觉-运动关联区。这对大脑跨时间的线索整合和感觉通道(如主要包含运动速度信号的光流)提出了挑战。此外，来自更高级别决策相关区域(主要是后部和额叶/前额叶区域)的新证据有助于修正我们的传统思维，即来自不同感觉模式的信号如何通过神经回路进行处理、汇聚和时刻积累，以形成统一的、最优的感知决策。本文是“多感官知觉中的决策和控制过程”主题的一部分。
Integrating noisy signals across time as well as sensory modalities, a process named multi-sensory decision making (MSDM), is an essential strategy for making more accurate and sensitive decisions in complex environments. Although this field is just emerging, recent extraordinary works from different perspectives, including computational theory, psychophysical behaviour and neurophysiology, begin to shed new light onto MSDM. In the current review, we focus on MSDM by using a model system of visuo-vestibular heading. Combining well-controlled behavioural paradigms on virtual-reality systems, single-unit recordings, causal manipulations and computational theory based on spiking activity, recent progress reveals that vestibular signals contain complex temporal dynamics in many brain regions, including unisensory, multi-sensory and sensory-motor association areas. This challenges the brain for cue integration across time and sensory modality such as optic flow which mainly contains a motion velocity signal. In addition, new evidence from the higher-level decision-related areas, mostly in the posterior and frontal/prefrontal regions, helps revise our conventional thought on how signals from different sensory modalities may be processed, converged, and moment-by-moment accumulated through neural circuits for forming a unified, optimal perceptual decision. This article is part of the theme issue ‘Decision and control processes in multisensory perception’.
