VIP en alerte : ces neurones qui d\u00e9clenchent l\u2019alarme face au danger<\/strong> <\/span><\/p>\n

Face \u00e0 une menace, le cerveau doit r\u00e9agir vite : fuir, se figer ou se d\u00e9fendre. Des neurones VIP situ\u00e9s au niveau du bulbe rachidien agissent comme un syst\u00e8me d\u2019alarme interne. Publi\u00e9s dans Advanced Science<\/em>, des travaux ont montr\u00e9 avec un test de visual looming<\/em>, simulant l\u2019approche d\u2019un pr\u00e9dateur a\u00e9rien que les neurones VIP d\u00e9tectent le danger et d\u00e9clenchent la fuite. Comprendre ce \u00ab\u202fcircuit d\u2019alerte\u202f\u00bb pourrait ouvrir de nouvelles perspectives pour d\u00e9crypter les m\u00e9canismes des troubles non-moteurs associ\u00e9s aux maladies neurod\u00e9g\u00e9n\u00e9ratives.<\/p>\n
