Researchers Say Spinach and Blueberries Improve
the Mental Abilities of Rats!
Naturally, this headline caught my attention.
I've always been interested in
rats, and most particularly in their mental abilities! It’s apparent to me that these rodents aren't
nearly as smart as they ought to be -- and I have first-hand knowledge of that
fact. I recall one rat from my childhood
who, if his mental facilities had been up to snuff, would have turned tail and
run when presented with the grim visage of my mother staring squint-eyed down
the barrel of a twelve-gauge shotgun.
Instead, this pest returned the stare and met its demise on our cellar
steps.
The
stairway didn't fare much better than the rat -- but that's beside the point.
It's obvious to me that our
tax dollars are well spent in performing experiments on rats. Don't they deserve to have improved mental
abilities? If rats were smarter, maybe they'd know enough to ring the doorbell when they wanted entrance to a
house, instead of fighting their way through the less-than-sanitary conditions
of a home's sewer pipes. Surely they would
prefer to make their appearance on the front porch, instead of poking up
through the water in the toilet bowl, especially when they can't be sure
whether or not said throne is in use at the time. I wonder, too, how many times they have almost reached their goal, only to hear
a thunderous WHOOSH that signaled a
speedy trip back down the pipe to the rodent's point of origin.
What really interested me in the
article was how scientists go about testing the mental abilities of rats. I have always associated rat tests with mazes, but not a single mention was made
of that time-honored puzzle. Instead,
the scientific conclusions were arrived at by another test. I quote the article in question.
"Rats
fed with a normal diet that contained 2% freeze-dried spinach learned to
associate the sound of a tone with an oncoming puff of air faster than those
fed regular rat chow.... The test measured the interval between the sound of
the tone and when the rats blinked."
Several questions come to mind. The first is, well…is there truly such a thing as rat chow?
Is that something you can pick up at the Farmers' Union or at Agway? What is the size of the market for such a chow?
I confess to calling rat chow by another name:
De-con.
Then, I wondered how these
scientists induced their subjects to eat
spinach. I know of only three people who
actually like the stuff, besides Popeye.
But then I remembered that these subjects were rats... rats that crawl
through sewers...and I realized that
spinach was probably a real treat.
As far as tones and puffs and
blinking -- well, this seems like a bit of wishful thinking on the scientists'
part. How can they be sure that the
rats' blinking wasn't just an involuntary
action? Maybe rats are prone to dry
eyes, especially if they are confined to cages that are constantly being
buffeted by blasts of air from well-meaning researchers?
Perhaps
rats were already smart and they
figured out that if they blinked properly like any respectable rat should, they
would continue to be fed that delicious spinach instead of ordinary, humdrum
rat chow.
Reading on, I learned that the
antioxidants in spinach blocked the effects of free radicals. I'm assuming
that free radicals are people like the members of PETA, who no doubt became
enraged upon discovering that rats were being puffed at with air, and began
campaigning for their release.
Apparently, as long as the scientists can continue to supply their rats
with spinach, these free radicals will stay blocked and the rodents will
remain status quo in their exalted position as scientific subjects.
It seems that blueberries fight the decline in rats’ memories. Another valiant effort! What a joy to realize that part of the money
that we send to the government each year supports this heroic endeavor. I can imagine the benefits now....
"Hey,
Ralph! Do you remember that puff of air we got on December 12, 1996?"
"Sure
do, Rudy! We flared our nostrils and
blinked three times, just to mess with their heads! What a riot!
We set them back six months, that time!"
"Yeah,
Ralph, but at least it got us off that diet of freeze-dried spinach we'd been
on for nine months, and into blueberries,
instead!"
And this, my friends, is how our
government allocates those tax monies we faithfully send to them each year on April
fifteenth.
Rats!
