Though it was based on very little evidence, many scientists thought that all mammalian brains, including the human brain, were made in the same way, with a
number
of neurons that was always proportional to the size of the brain.
Now, you may have heard or read somewhere that we have 100 billion neurons, so 10 years ago, I asked my colleagues if they knew where this
number
came from.
I've been digging through the literature for the original reference for that number, and I could never find it.
It seems that nobody had actually ever counted the
number
of neurons in the human brain, or in any other brain for that matter.
Because we found that the relationship between the size of the brain and its
number
of neurons could be described mathematically, we could calculate what a human brain would look like if it was made like a rodent brain.
So the human brain may be remarkable, yes, but it is not special in its
number
of neurons.
So the total energetic cost of a brain is a simple, linear function of its
number
of neurons, and it turns out that the human brain costs just as much energy as you would expect.
So the reason why the human brain costs so much energy is simply because it has a huge
number
of neurons, and because we are primates with many more neurons for a given body size than any other animal, the relative cost of our brain is large, but just because we're primates, not because we're special.
Last question, then: how did we come by this remarkable
number
of neurons, and in particular, if great apes are larger than we are, why don't they have a larger brain than we do, with more neurons?
They just can't afford the energy for both a large body and a large
number
of neurons.
We calculated on the one hand how much energy a primate gets per day from eating raw foods, and on the other hand, how much energy a body of a certain size costs and how much energy a brain of a certain
number
of neurons costs, and we looked for the combinations of body size and
number
of brain neurons that a primate could afford if it ate a certain
number
of hours per day.
And what we found is that because neurons are so expensive, there is a tradeoff between body size and
number
of neurons.
So it's either a large body or a large
number
of neurons.
My answer is that we have the largest
number
of neurons in the cerebral cortex, and I think that's the simplest explanation for our remarkable cognitive abilities.
And what is it that we do that no other animal does, and which I believe was fundamental to allow us to reach that large, largest
number
of neurons in the cortex?
We all know quite a
number
of people who have everything that it would take to be happy, and they are not happy, because they want something else or they want more of the same.
This is a disease that affects a large
number
of individuals.

number
of community meetings in rooms like this to introduce the planning process, and people came out from all over the city, including areas that were stable neighborhoods, as well as areas that were beginning to see a lot of vacancy.
Now, to quickly give you all a sense of a scale, because I know that sounds like a big number, but I don't think you quite understand until you look at the city map.
It wasn't going to be our traditional residential neighborhoods as we had before, and urban agriculture, while a very productive and successful intervention happening in Detroit, was not the only answer, that what we had to do is look at these areas where we had significant vacancy but still had a significant
number
of population of what could be new, productive, innovative, and entrepreneurial uses that could stabilize those communities, where still nearly 300,000 residents lived.
Industrial machines are being equipped with a growing
number
of electronic sensors that allow them to see, hear, feel a lot more than ever before, generating prodigious amounts of data.
But then we hit a new challenge, and that's the
number
of skilled prosthetists who are able to fit knees.
It could be a phone number, it could be an e-mail address, it could be a postal address.
And I read out that
number
to them, and they use it to top up their phone.

number
of those healthy habits that a given person had.
Hundreds of these brightly-colored sculptures decorated the park for a
number
of weeks, and unlike work that's exhibited in a more neutral space, like on the walls of a gallery or a museum, this was work that was really in dialogue with this place, and in a lot of ways, The Gates was really a celebration of Frederick Olmsted's incredible design.
So I worked for quite a long time on these models and I implemented them on a
number
of robots.
It's the
number
