Résumé

Orexins (Oxs) are multifunctional neuropeptides, secreted from the lateral hypothalamus, that stimulate feeding behavior and energy expenditure. In this study, the direct effects of Oxs on the membrane properties of trigeminal motoneurons (TMNs) were examined, which critically participate in the genesis of rhythmical oral motor activities underlying suckling and mastication. Sprague-Dawley rats (3-6 day-old) were used to obtain whole-cell patch-clamp recordings from TMNs. Bath application of Ox-A depolarized the membrane potential and induced inward current, wherein Na
