Pregnant rats were exposed to an oxygen depleted atmosphere (13% oxygen in nitrogen) at normal pressure in 2-hr daily sessions extending over approximately the last 14 days of pregnancy. Their progeny were compared with control progeny in terms of age of eye-opening, open-field behavior, and Hebb-Williams maze problem solving ability. The groups were not distinguishable by their performance in the open-field, but the experimental animals opened their eyes significantly earlier and made significantly more errors on Hebb-Williams maze problems.
在怀孕的最后约14天里，每天将怀孕的大鼠置于常压下的缺氧环境（氮气中含13%氧气）中2小时。将它们的后代与对照后代在睁眼年龄、旷场行为和赫布 - 威廉姆斯迷宫问题解决能力方面进行比较。两组在旷场中的表现没有差异，但实验动物睁眼明显更早，并且在赫布 - 威廉姆斯迷宫问题上犯的错误明显更多。
