And this is when it all started to fall apart.

Theyd had exactly the same dose as the teenagers
它們喝下的酒精量和青春期老鼠是一樣的
but clearly couldnt hold it.

Maybe the third would be different?
第三只是不是能成功呢
No.
也沒有
You'd imagine that there would either be no difference
你原先認為兩者的反應會相同
or in fact it would go the other way.
但是事實卻截然相反
That a young if you like a young brain would be more affected.
年輕老鼠的大腦在機能上要好一些
For these kinds of tasks we think that the adolescents are less sensitive
從實驗來看 青春期老鼠更能抵抗酒精
because of the brain regions that are responding to those tasks
它們大腦中對這些任務作出反應的區域
are different in terms of their developmental stage than adults.

So to drink more to be able to cope with more booze on board
所以它們能喝更多 抵抗力更強
but thats not to say theres no risk of damage.
但也并不是說 它們就不會受酒精損害
