Le sucre : poison légal

Le sucre est une drogue plus addictive que la cocaïne et pourtant il est partout ! Début des années 2000. Neurocampus de Bordeaux. Serge Ahmed, directeur de recherche au CNRS, est passionné par les mécanismes de l’addiction qu’il étudie depuis de nombreuses années. En travaillant sur des rats de laboratoire, il a démontré que l’accès prolongé à des drogues telles que l’héroïne ou la cocaïne, entraîne des modifications neurobiologiques dans le cerveau. Pour étudier ces addictions, il place des rats dans une cage avec un levier qui, quand il est pressé par le rongeur, actionne l’injection d’une dose de drogue. Mais l’expérience n’est pas complète. Le rongeur n’a pas le choix. Peut-être est-il addict «par défaut»? Le professeur Ahmed décide d’offrir au rat une alternativeà la drogue.Il choisit un produit apprécié par les animaux : De l’eau sucrée.Hébergé par Audiomeans.
