Quand le protoxyde d’azote ne fait plus rire : épidémiologie, aspects analytiques, incidences clinique et médicojudiciaire

2020

Objectifs Le 11/12/2019, le Senat adoptait la proposition de loi tendant a proteger les mineurs des usages dangereux du protoxyde d’azote (N2O). Cette utilisation n’est pas recente, son abus non plus. Neanmoins, ces dernieres annees sont marquees par un regain d’interet de son usage recreatif, notamment par une population jeune, souvent en association avec d’autres substances psychoactives. Les consequences medicales et medicolegales potentiellement graves que ce detournement peut entrainer en font actuellement une preoccupation grandissante des cliniciens et toxicologues. Il s’agit ici de faire un etat des lieux de la litterature scientifique sur le sujet. Methode Differentes sources d’inf…

A basal ganglia-like cortical-amygdalar-hypothalamic network mediates feeding behavior.

2020

International audience; The network connecting the insular cortex, the central nucleus of the amygdala, and a caudal hypothalamic nuclear complex including the parasubthalamic nucleus (PSTN) is of interest due to its role in controlling feeding behavior. Here, we show that the organization of this network is similar to that of the basal ganglia network, implying that both fit within a simplified structural plan of the forebrain. Then, we demonstrate that the PSTN complex modulates behavior in response to hedonic factors normally inducing a “reward effect.” The PSTN complex is involved in a “non-feed” response equivalent of a “non-reward” evaluation: “I don’t want to consume this food, recog…
