Yawning is a very common and phylogenetically old behavioural event that occurs in vertebrates under different conditions. Yawning appeared very early in vertebrate history, with contagiousness evolving much later.
Yawning has many consequences, including opening of the eustachian tube, tearing, inflating the lungs, stretching and signaling drowsiness, but these may be incidental to its primal function which may something as unanticipated as sculpting the articulation of the gaping jaw during embryonic development.
Selecting a single function from the many options may be an unrealistic goal. However, reviewing the disparate facts, we may be impressed that yawning is associated with the change of behavioral state wakefulness to sleep, sleep to wakefulness, alertness to boredom, threshold of attack, sexual arousal, switching from one kind of activity to another. (R. Provine)
We are proud to announce the First International Conference on Yawning. These two days meetings bring together leading international speakers to review both emerging information and its convergence with current understanding. Join leaders in the field on June 24 & 25, 2010 in Paris.
The FICY 2010 will provide a forum for in-depth assessment of the challenges involved in the dynamic and fast moving field of research and conjectures on this intriguing behavior : yawning. Over 20 leading experts from 8 countries around the world have already confirmed they will be participating. FICY will bring together clinicians, researchers, ethologists, pharmacologists and other allied professionals to discuss and present the latest important developments in the field.

Le bâillement est un comportement très répandu parmi les vertébrés car phylogénétiquement ancien et survenant dans des circonstances variées. Le bâillement apparaît dès la fin du premier trimestre de la grossesse mais son caractère contagieux n'est manifeste qu'après 4 à 6 ans, chez l'homme.
Bâiller à de multiples conséquences: ouvrir la trompe d'Eustache, larmoyer, gonfler les poumons, s'étirer ou exprimer de la lassitude, par exemple, mais tout cela n'est sans doute qu'incident par rapport à son rôle primordial qui est, pourquoi pas, d'assurer la formation des articulations temporo-mandibulaires pendant la grossesse.
Ne retenir qu'une seule fonction parmi toutes celles envisagées est sans doute suivre une fausse piste. Quoiqu'il en soit, en revoyant tant de faits disparates, on peut retenir que le bâillement est un comportement apparaissant à des moments de transition entre deux états: éveil - endormissement, satiété - faim, pulsion sexuelle ou agressive - relaxation, décharge émotionnelle.
Nous sommes heureux de vous annoncer la tenue de la Première Conférence Internationale sur le Bâillement qui aura lieu à Paris les 24 et 25 juin 2010.
