That settles it then, we're not only becoming cyborgs, we have super powers. Now who's working on that nose laser? In all seriousness, this is fascinating, that study on bees should also be done to bloodhounds!
I loved this video! Never really thought about how something so seemingly simple as the nose has such a complex job in deciphering the nature of smell. Do you have any more resources on the vibration model?
Suzana Herculano-Houzel: What is so special about the human brain?
Suzana Herculano-Houzel summarizes two decades of her research work focused on answering the question How do we explain the extraordinary cognitive abilities of human beings, including:
How she verified that human beings on average have ~86 billion neurons.
Brains of different animals are not made the same way. In particular, in a rodent (such as a rats and hamsters) the number of neurons is not proportional to the size of the brain, whereas in primates (such as chimps and humans), the number of neurons is proportional to the size of the brain.
Energy consumption of a brain is linear in the number of neurons.
How the brain size had been growing slowly but couldn't grow faster because of unavailability of energy. And how everything changed when we learnt how to cook!
This is really an amazing video. I love the irony that as a race the thing that propelled us to our current sentience level was the advent of cooking, but now thats causing all sorts of problems like obesity and unbalanced nutrition.
I wonder what sorts of mutations caused the rift in ...
