※ 引述《SuperMaster (神手)》之铭言：
: 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?
^^^^^^^^^^^^^^
这是作者的疑问
: Recently, we tested the possibility that one of the
: hormone’s actions outside the brain might be responsible.
^^^^^^^
这是作者对他的疑问的假设
: 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
^^^^^^^^^
这一句就是他想要证实的: glucose会造成enhance memory
所以他想要反向证明: 这个enhance memory不是由adrenaline直接造成
而是由glucose
那要怎么证明？
1.单纯打glucose进去也会有类似的效果
2.就算有adrenaline，若不造成glucose上升就没有memory enhancement
3.所以用adrenergic blocker
