环境线索通常会触发对过去事件的记忆（联想提取），这些记忆是对即将发生的经历的一种预测。当过去和现在出现分歧时，学习是由预测违规的检测驱动的。使用颅内脑电图（iEEG），我们表明，关联预测违规引起增加的低频功率（在慢θ范围内）在人类海马，这种低频功率的增加是由条件是否允许预测产生调制，增加后迅速发病的那一刻的侵犯，并在低频功率的变化不存在于相邻的嗅周皮层。这些数据表明，关联失配计算海马内的线索触发预测，违反了即将到来的经验。
Environmental cues often trigger memories of past events (associative retrieval), and these memories are a form of prediction about imminent experience. Learning is driven by the detection of prediction violations, when the past and present diverge. Using intracranial electroencephalography (iEEG), we show that associative prediction violations elicit increased low-frequency power (in the slow-theta range) in human hippocampus, that this low-frequency power increase is modulated by whether conditions allow predictions to be generated, that the increase rapidly onsets after the moment of violation, and that changes in low-frequency power are not present in adjacent perirhinal cortex. These data suggest that associative mismatch is computed within hippocampus when cues trigger predictions that are violated by imminent experience.
