他注意到，手术并未导致“明显的行为变化”，除了“短期记忆严重流失。”
It was so severe, it prevented Henry from navigating his own house and recognizing his doctors.

但亨利其他类型的记忆，也即无需刻意思考的习惯，比如骑自行车等，并没有受到影响，这就是所谓的“内隐记忆”。
He also kept some conscious or “explicit” memories.
他还保留了一些有意识记忆，又名“外显”记忆。

在这段90年代初的录音中，他还和他的医生探讨过历史：
What happened in 1929?

亨利真正受损的是他的“情景记忆”，是有关他个人经历的记忆。

当他的医生问他，“你还记得昨天你做了什么吗？”
he replied: "No, I don't."
