In several of the studies, when stressed-out female rats had their ovaries (the female reproductive organs) removed, their chemical responses became equal to those of the males.

在几项研究中，当受到压力的雌鼠的卵巢（雌性的生殖器官）被拿掉后，它们的化学反应变得和那些雄性的一样了。

The Tel Aviv team wanted to find out if those differences are significant enough to create two distinctly different types of brain, just as there are distinctly male and female reproductive organs.

特拉维夫大学这个研究团队希望查明这些差别是否足够显著，形成两种完全不同类型的大脑，就像男女生殖器官的差别一样。
