Grand Old Pachyderm Thursday


(August 12)

Conservationists have designated August 12 as World Elephant Day to raise awareness about conserving these majestic animals. Elephants have many engaging features, from their incredibly dexterous trunks to their memory abilities and complex social lives.

But there is much less discussion of their brains, even though it stands to reason that such a large animal has a pretty big brain (about 12 pounds). Indeed, until recently very little was actually known about the elephant brain, in part because obtaining well-preserved tissue suitable for microscopic study is extremely difficult.

That door was opened by the pioneering efforts of neurobiologist Paul Manger at the University of the Witwatersrand in South Africa, who obtained permission in 2009 to extract and preserve the brains of three African elephants that were scheduled to be culled as part of a larger population management strategy. We have thus learned more about the elephant brain in the last 10 years than ever before.

The research shared here was conducted at Colorado College in 2009-2011 in cooperation with Paul Manger, Columbia University anthropologist Chet Sherwood and neuroscientist Patrick Hof of the Icahn School of Medicine at Mount Sinai. Our goal was to explore the shapes and size of neurons in the elephant cortex.

    If only the Republicans were as intelligent as their mascots.

    Using a Skunk as a mascot would be more apropos, but offensive to Skunks.

    Looks like I may do a little mowing tomorrow. Just a tad, around the house and the ditch and down there in the low area that touched the ditch, Carter Rd. It’s all peat a eights of the way up. Used to be a swamp down there and the other side of Carter Road.

    We had lots of rain at long last, a couple days ago. My plants REALLY rallied. The hostas, which are everywhere, were standing up proudly, their leaves off the ground. I watered them pretty often, but there is nothing like rain water. Our well water, which probably was nutritious a couple centuries ago, suffers from the farm fields and all the crap they spray on them.

    Other plants also rallied, looked way better than they had.
