对于任何一个人来说，学习或记忆形成的速度都会随着时间的推移而变化，部分原因是大脑状态的时刻波动。功能神经成像揭示了学习和记忆的神经关联，但在这里，我们问的是，神经成像是否可以通过检测大脑状态来因果地增强人类的学习，这些状态揭示了一个人何时准备学习或不准备学习。海马旁皮质(PHC)对于场景记忆的形成是必不可少的。在这里，PHC中的激活被实时监控，当参与者进入学习新奇场景的“好”或“坏”大脑状态时，场景呈现被触发。随后的识别记忆对于呈现在“好”状态下的场景比“坏”状态下的场景更准确。这些发现表明，神经成像可以实时识别增强或抑制学习和记忆形成的大脑状态，有关这种大脑状态的知识可能有助于加快教育和培训。此外，使用功能神经成像作为研究人脑的因果工具，而不是相关工具，可能会为人类认知的神经基础打开新的洞察力。
The rate of learning or memory formation varies over time for any individual, partly due to moment-to-moment fluctuation of brain state. Functional neuroimaging has revealed the neural correlates of learning and memory, but here we asked if neuroimaging can causally enhance human learning by detection of brain states that reveal when a person is prepared or not prepared to learn. The parahippocampal cortex (PHC) is essential for memory formation for scenes. Here, activation in PHC was monitored in real-time, and scene presentations were triggered when participants entered “good” or “bad” brain states for learning of novel scenes. Subsequent recognition memory was more accurate for scenes presented in “good” than “bad” brain states. These findings show that neuroimaging can identify in real-time brain states that enhance or depress learning and memory formation, and knowledge about such brain states may be useful for accelerating education and training. Further, the use of functional neuroimaging as a causal, rather than correlative, tool to study the human brain may open new insights into the neural basis of human cognition.
