Logiciel associé A3 - Comment produire une réponse adaptée ? Nous savons donc que le système nerveux est constitué de centres nerveux reliés aux organes par des nerfs... Mais comment ça marche ? Pour comprendre, étudions le comportement d'une grenouille... Grenouille intacte Observe bien le comportement de la grenouille : - elle voit l'insecte (l'oeil bouge) - elle bondit pour le saisir (mouvement) Tu vas maintenant chercher le rôle des différents organes du système nerveux : le cerveau, le nerf optique qui est un nerf sensitif, la moelle épinière, les nerfs de la cuisses qui sont des nerfs moteurs. ► Clique sur les ciseaux pour détruire un des organes et observer le résultat sur le comportement de la grenouille. Note au fur et à mesure les résultats dans le tableau que tu trouveras ici (garde l'onglet ouvert) : Grenouille avec le cerveau détruit Grenouille avec les nerfs optiques (sensitifs) détruits Grenouille avec la moelle épinière sectionnée Grenouille avec les nerfs des cuisses sectionnés
Gravity-defying video illusion goes with the flow | Games Blog The video you’re about to see by master illusionist Brusspup looks like some kind of expensive CGI footage scraped off the cutting room floor of the Matrix movies. In fact, though, all it takes is a hose, a subwoofer, a video camera, and a little technical know-how: Want to know how it’s done? Brusspup creates the stunning effect by exploiting an aspect of the way video cameras work. The camera records at 24 frames per second; by using the speaker to vibrate the water hose at a corresponding 24Hz (24 vibrations per second), Brusspup exactly matches the framerate.
