Avez-vous pris un caf\u00e9 ce matin ? Une partie de la vie sociale d'un scientifique se d\u00e9roule pendant la pause caf\u00e9 lors de conf\u00e9rences scientifiques, de s\u00e9minaires de laboratoire et au quotidien dans le laboratoire. Mais le caf\u00e9 est aussi un sujet scientifique. Principalement en raison de la caf\u00e9ine, un stimulant du syst\u00e8me nerveux central (SNC) et la drogue psychoactive la plus consomm\u00e9e au monde.<\/p>\n\n\n\n

Alors, pour c\u00e9l\u00e9brer le caf\u00e9 - ou pour vous conseiller d'y aller doucement, voyons comment fonctionne la caf\u00e9ine.<\/h3>\n\n\n

La source la plus connue est le grain de caf\u00e9, un terme impropre pour d\u00e9signer la graine de la plante Coffea. Les boissons contenant de la caf\u00e9ine sont ing\u00e9r\u00e9es pour soulager ou pr\u00e9venir la somnolence et pour am\u00e9liorer les performances. Pour fabriquer ces boissons, la caf\u00e9ine est extraite par trempage du produit v\u00e9g\u00e9tal dans l'eau, un processus appel\u00e9 infusion. Ces boissons, telles que le caf\u00e9, le th\u00e9 et le cola, sont tr\u00e8s populaires ; en 2014, 85% des adultes am\u00e9ricains consommaient quotidiennement une forme de caf\u00e9ine, \u00e0 raison de 164 mg en moyenne.<\/p>\n\n\n

Il existe plusieurs m\u00e9canismes d'action connus pour expliquer les effets de la stimulation. Le plus important est qu'il bloque de mani\u00e8re r\u00e9versible l'action de l'ad\u00e9nosine sur son r\u00e9cepteur et emp\u00eache par cons\u00e9quent l'apparition de la somnolence induite par l'ad\u00e9nosine. Il stimule \u00e9galement certaines parties du syst\u00e8me nerveux autonome.<\/p>\n\n\n
