"From the Ted Talk by Suzana Herculano-Houzel: What is so special about the human brain?"

Unscramble the Blue Letters

So the human brain is larger than it should be, it uses much more energy than it should, so it's special. And this is where the story started to boehtr me. In bioogly, we look for rules that apply to all animals and to life in general, so why should the relus of evolution apply to everybody else but not to us? Maybe the problem was with the basic assumption that all bianrs are made in the same way. Maybe two brains of a similar size can actually be made of very different numbers of neurons. Maybe a very large brain does not necessarily have more neurons than a more modest-sized brain. Maybe the human bairn actually has the most neurons of any brain, regardless of its size, especially in the cerebral cortex. So this to me became the important question to answer: how many neurons does the human brain have, and how does that cropame to other animals?
