适应性大脑功能要求社会和自然环境的感官印象动态地融入内在的大脑活动。虽然大脑状态之间的动态切换已经很好地表征在休息状态收购，这些状态转换的重塑参与自然刺激仍然知之甚少。在这里，我们表明，在功能磁共振成像测量的大脑状态的时间动态，重塑从主要是两个相对模糊的状态之间的过渡，在休息，对一系列定义明确的功能状态在观看电影的过渡时间对齐的电影的特定功能。这些大脑状态的表达随不同的生理状态而变化，并反映了电影中主观评价的参与度。总之，大脑状态的数据驱动解码揭示了功能网络表达的独特重塑和可靠的状态转换，这些状态转换伴随着从休息状态到生态有效的感官体验中的感知沉浸的切换。从休息到感知周围环境的转变需要对大脑活动进行根本性的重组。在这里，作者展示了大脑状态动力学的根本重塑如何支持自然主义刺激的感知参与。
Adaptive brain function requires that sensory impressions of the social and natural milieu are dynamically incorporated into intrinsic brain activity. While dynamic switches between brain states have been well characterised in resting state acquisitions, the remodelling of these state transitions by engagement in naturalistic stimuli remains poorly understood. Here, we show that the temporal dynamics of brain states, as measured in fMRI, are reshaped from predominantly bistable transitions between two relatively indistinct states at rest, toward a sequence of well-defined functional states during movie viewing whose transitions are temporally aligned to specific features of the movie. The expression of these brain states covaries with different physiological states and reflects subjectively rated engagement in the movie. In sum, a data-driven decoding of brain states reveals the distinct reshaping of functional network expression and reliable state transitions that accompany the switch from resting state to perceptual immersion in an ecologically valid sensory experience. The transition from resting to perceiving one’s milieu requires a fundamental reorganization of brain activity. Here, the authors show how a fundamental reshaping of brain state dynamics supports perceptual engagement in naturalistic stimuli.
