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
(5)large effect on brain function?
Recently, we tested the possibility that one of the
hormone’s actions outside the brain might be responsible.
Since one consequence of adrenaline release in an animal
is an increase in blood glucose levels, we examined the
(10)effects of glucose on memory in rats. We found that glu-
cose injected immediately after training enhances memory
tested the next day. Additional evidence was provided by
negative findings: drugs called adrenergic antagonists,
which block peripheral adrenaline receptors, disrupted
(15)adrenaline’s ability to regulate memory but did not affect
memory enhancements produced by glucose that was not
stimulated by adrenaline. These results are as they should
be if adrenaline affects memory modulation by increasing
blood glucose levels.
