Brain size and neuron numbers drive differences in yawn duration across mammals and birds

Brain size and neuron numbers drive differences in yawn duration across mammals and birds

Massen, Hartlieb, Martin et al. study the duration of yawns across mammals and birds to test the brain cooling hypothesis. Consistent with this hypothesis, their findings indicate that brain mass and neuron numbers influence yawn duration, and that mammals yawn longer than birds with similar brain a...
