OBJECT #18: Brain book ends

    Brain anatomy seems to be a theme I can’t get away from.  The download-able brain hemisphere hat on my website has become the most popular free download item on my site.  It’s been used at science fairs from San Diego, CA, to Cambridge, England.  School teachers have used it in their classrooms then posted the pictures on their blogs.  An international publishing company discovered it and asked me to design a hat that was half brain/half elephant, for one of their advertising campaigns.  A neuroscientist emailed me about getting some printed to use as “microgifts” for his interns.  And, most recently, a brain imaging company in Boston had me do a mouse pad design using a modified version of the brain hat.

    This set of brain book ends was given to me by a former student who is now a young adult.  When she saw this item she said it just screamed my name, so she had to get it for me.  So now I have brain hemispheres between which I can keep all my books about brain hemispheres.  Works out nicely.

    I had to consult one of these books recently to do some fact checking for the left hemisphere brain mouse pad project.   According to this fairly scholarly book, the hemispheres are not quite as dissimilar as most popular science articles would have you believe, although language does seem to be solidly on the left side for about 90 percent of the population.  To date, there are no good theories as to why this should be so.  It just is.  (The same for handedness.  Why most people are right handed is a complete mystery.)  The unlucky 10 percent, whose brains have decided to use the right side for language, will almost certainly have issues with language processing, though in most cases the problems are mild enough that the affected persons can overcome the problems or learn to work around them.  (Many people who have this condition are unaware of it.)

    The left side of the brain has two special areas that the right side does not have--areas devoted to processing words.   Both areas bear the names of the people who discovered their significance.  Broca’s area is where we construct sentences before (or as) we say them.  Wernicke’s area is where we process the language that we hear, turning sounds into meaningful ideas.  These two areas connect to other areas of the brain, also.  No part of the brain functions independently from the others.

    This is the right hemisphere brain mouse pad.  The right hemisphere is usually non-verbal.  It is the center for creativity, music, and art.  It sees relationships between things, and understands “the whole picture.”  It is from the right hemisphere that those “Eureka!” moments come.

OBJECT #3: Replica skulls

    I’m not quite sure why I have a skull collection on the mantle in my basement workshop.  I’ve never been a collector of any sort (although I do remember collecting those “Wacky Cards” when I was a kid-- the ones that came with bubble gum and featured silly ads for funny (parody) products such as “Vomit Cleanser” and “Swiss Mess” hot chocolate packets).  (Okay, I did keep all my baby teeth in a little plastic case, but wasn’t throwing them out at the end of that silly Tooth Fairy charade a bit of a waste?)  And though I admire naturalists who have vast collections from nature, I’ve never really thought of myself as one.   Sure, I had a fetal pig in a jar as part of my bedroom decor when I was about 12, but I had normal things, too, like Star Trek posters on the wall and stuffed animals on my bed.


    I think my adventures with skulls began when I started teaching art.  I was looking for interesting shapes that my students could draw using only a monochrome pallet (no color).  I wanted objects that were odd enough that the students wouldn’t be overly concerned about getting it to look “just right.”   I think I saw these replica skulls in a surplus catalog (probably American Science and Surplus) and thought the price was low enough that I didn’t have much to lose if they turned out to be a disappointment.  When they arrived I was quite delighted with them and they’ve been a standard still life item in my art classes every since.  They are made of tough resin, and are therefore practically indestructible, but are so lifelike that my students often don’t realize they aren’t real.  I’ve got a coyote, a cougar, an ape, and a small monkey.  I would have purchased more, but those were the only skulls listed.  That’s surplus for you.

    My favorite assignment is to have the students draw the skulls using black and white conte pencils on gray paper.  I’ve found that this is assignment almost always produces nice drawings, even with beginning students.  I’ve also had them try white pencil on black paper, and this works pretty well, too.

    I’ve always had in the back of my mind that I would use these skulls somehow as part of a hands-on exhibit in my summer science museum project (a free hands-on science museum at various outdoor venues in my town).   I have a few other skulls I could use, too, as well as a picture book I came across, “The Skull Alphabet Book” by Jerry Pallota.  This book is the most kid-friendly skull book I’ve ever seen.  It was a “must-purchase” for me.  The whimsical sense of humor is so right down my alley, and I love the simple and striking (artistic) compositions on each page.   It’s a brilliant combination of science, humor and artwork.  (I don’t understand why the author felt compelled to hide the faces of US presidents in the pictures, but, oh well.)   The first page sets the tone: Warning-- this book contains the alphabet. If you are afraid of the alphabet, do not read any further,”  What a clever way to get the focus of the skulls being scary!  After reading, “A is for... we are not going to tell you!” I was sold.  It’s an engaging book that makes you think while you are reading.  Some day I will think of a way to combine this book with my skull collection and make a fun hands-on exhibit.   Until then, I guess both my collection and the book are... “junk in my basement.”
