(Phys.org)—A trio of researchers with the State University of New York has found a link between yawn duration and neuron density. In their paper published in the journal Biology Letters, Andrew Gallup, Allyson Church and Anthony Pelegrino describe a study they carried out comparing yawn lengths between species, what they found and their ideas on the purpose of yawning.
