"Cephalization" means that the animal has a defined "head" region in which there is a lot of nervous tissue (such as the brain in humans). Sponges are not cephalized because they do not have defined head region nor do they have a central location for their nervous system. The nervous system in sponges is very loose because their cells generally work more individually as opposed to being commanded by a nervous system.
