Ever wondered how many neurons are in the human brain? Meet Suzana Herculano-Houzel, a professor at Vanderbilt University whose pioneering "brain soup" technique made it possible to accurately count the number of neurons in brains of all sizes. From elephants, to birds, whales, monkeys and even cats and dogs, she has studied over 100 species and her findings have fundamentally altered our understanding of interspecies neurology. Herculano-Houzel participated in the "Pioneers in Science Program" at the 2019 World Science Festival. The "Pioneers in Science" program gives high school students from around the globe rare and intimate access to some of the world’s most renowned scientists in a town hall-style discussion.
