※ 引述《SuperMaster (神手)》之銘言：
: Although the hormone adrenaline is known to regulate
: memory storage, it does not pass from the blood into
: brain cells. We are faced with an apparent paradox: how
: can a hormone that does not act directly on the brain
: have such a large effect on brain function?
^^^^^^^^^^^^^^
這是作者的疑問
: Recently, we tested the possibility that one of the
: hormone’s actions outside the brain might be responsible.
^^^^^^^
這是作者對他的疑問的假設
: Since one consequence of adrenaline release in an animal
: is an increase in blood glucose levels, we examined the
: effects of glucose on memory in rats. We found that glucose
: injected immediately after training enhances memory tested
: the next day. Additional evidence was provided by negative
^^^^^^^^^
這一句就是他想要證實的: glucose會造成enhance memory
所以他想要反向證明: 這個enhance memory不是由adrenaline直接造成
而是由glucose
那要怎麼證明？
1.單純打glucose進去也會有類似的效果
2.就算有adrenaline，若不造成glucose上昇就沒有memory enhancement
3.所以用adrenergic blocker
