WTF Fun Fact 12447 – The Tongue of a Woodpecker

We never really thought about it up until now, but it makes sense that woodpeckers would have to have some kind of mechanism to protect their brains from getting tossed around in their skulls while they hammer away. But in 2010, a team of Chinese scientists figured it out – and it’s fascinating.

To be honest, we didn’t even realize woodpeckers have such long tongues. But doing all that pecking is a way to chip into beetle grub nests, and their long tongues allow them to get in there without having to bash a big old hole in the tree like the Kool-Aid Man.

A woodpecker’s head strikes with around 1,000 times the force of gravity, about ten times more than what would definitely kill a human.

Their sharp beaks help them out a lot, as do their strong neck muscles, but up until relatively recently, no one knew how their heads could absorb the shock of that motion.

WTF Fun Fact 12403 – Your Brain on Math

Mathematics is a strange beast. It uses our language, but it isn’t quite the same – our brains hear it entirely differently from everyday speech. For example: when we hear a sentence like “cats like warm milk,” our brains process that information mainly in the left hemisphere. Something like “eight plus one is nine,” though, will fire neurons in both.

A study published in the journal Current Biology took a closer look at how our brains process mathematics (as opposed to regular speech). While our brains process ordinary language in the left hemisphere, math triggers neurons in both hemispheres.

The neuroscientists from the Universities of Tübingen and Bonn said in an interview: “We found that different neurons fired during additions than during subtractions.”

Esther Kutter, a doctoral candidate involved with the research group, confirmed: “Even when we replaced the mathematical symbols with words, the effect remained the same. For example, when subjects were asked to calculate ‘5 and 3’, their addition neurons sprang back into action; whereas for ‘7 less 4,’ their subtraction neurons did.”

The lead author of the study Prof. Dr. Dr. Florian Mormann of the Department of Epileptology at University Hospital Bonn, remarked on the study’s significance: “This study marks an important step towards a better understanding of one of our most important symbolic abilities, namely calculating with numbers.” – WTF Fun Facts

WTF Fun Fact - More Neurons As An Embryo

At the time of birth, a baby’s brain has roughly 100 billion neurons, but it began with nearly twice as many as an embryo. Starting in the third trimester, the brain eliminates unnecessary neurons via a process known as apoptosis. – WTF Fun Facts
