To compare insect brains, make bug brain 'soup'
To approximate how many brain cells make up insect brains, neuroscientists made “brain soup.” In addition to revealing interesting insights into the evolution of insect brains, the work provides a more meaningful metric than traditional studies measuring brain size or weight. The surprisingly simple technique—mashing up brains into a “soup”—let researchers discover that certain species of bees have a higher density of brain cells than even some species of birds, whereas ants turned out to have fewer brain cells than originally expected.
