I am a little disappointed to find no comparison to the dolphin brain in the talk about the number of neurons! Why elephant? If it was about the size it could have been the animal with the largest brain out there (which happens to be a cetacean, like dolphins)!
- omalleyt 11y agoYup! And the article incorrectly states that humans have more cortical neurons than any other animal. Pilot whales (a misnomer, they're dolphins) have more cortical neurons than humans: https://en.wikipedia.org/wiki/List_of_animals_by_number_of_neurons#Cerebral_cortex https://en.wikipedia.org/wiki/List_of_animals_by_number_of_n... Which is especially important because the article takes as given that the number of cortical neurons is what makes humans special.

- bostonpete 11y agoThe comparison to elephants was made to illustrate the fact that number of neurons isn't closely correlated with brain size. Seemed like a reasonable point of comparison to me.
