The first study to actually count the number of cortical neurons in the brains of a number of carnivores, including cats and dogs, has found that dogs possess significantly more of them than cats. Read More

When she finally applied her "brain soup" technique to the human brain, Herculano-Houzel discovered we have an average of 86 billion neurons. Surprisingly, though, the neuron density is the same as in other primates, showing a clear evolutionary pattern from monkeys to humans. “We somehow manage to have this large brain with a large number of neurons; but it’s still just a regular primate brain,” says Herculano-Houzel.

Artificial kidneys, gay-straight alliances and junkyard batteries captured readers' attention in 2016. Read More

Research by Associate Professor of Psychology Suzana Herculano-Houzel finds that human intelligence comes from the number of neurons in our brains—and it was the invention of cooking that made neuron development possible. Read More

The first study to systematically measure the number of neurons in the brains of birds has found that they have significantly more neurons packed into their small brains than are stuffed into mammalian and even primate brains of the same mass. Read More
