The neural correlates supporting our perceptual experience of the world remain largely unknown. Recent studies have shown how stimulus detection and related confidence involve evidence accumulation (EA) processes similar to those involved in perceptual decision-making. Here, we propose that independently from any tasks, percepts are not static but fade in and out of consciousness according to the dynamics of a leaky evidence accumulation process (LEAP), and that confidence corresponds to the maximal evidence accumulated by this process. We discuss the implications and limitations of our proposal, assess how it may qualify as a neural correlate of consciousness, and illustrate how it brings us closer to a mechanistic understanding of phenomenal aspects of perceptual experience like intensity and duration, beyond mere detection.

支持我们对世界的感知体验的神经相关性在很大程度上仍然未知。最近的研究表明，刺激检测和相关信心如何涉及与感知决策相关的证据积累 (EA) 过程。在这里，我们建议独立于任何任务，感知不是静态的，而是根据泄漏证据积累过程（LEAP）的动态淡入和淡出意识，并且置信度对应于该过程积累的最大证据。我们讨论了我们的提议的含义和局限性，评估它如何成为意识的神经关联，并说明它如何使我们更接近于机械地理解感知体验的现象方面，如强度和持续时间，而不仅仅是检测。
