ABSTRACT
The ganglion cell easily produces signs by means of electrical potential differences caused by the movements of ions. Ganglion cells and the nervous system are also building blocks of the body, but their sign function can remain in the icon-stage. They do not form spinal syntactic structures necessary for the transmission of experience. The nerve-nets of the coelenterata consist of such cells. The sign-function of these cells does not transcend the body boundaries and the fiber-net that exists between these cells. The polarized ganglion cell is capable of loosing its tie to the icon-phase of the communication and, therefore, its ties to the body. The axons of cerebellar granular cells arise sometimes from cell bodies—more often though from dendrites. The cerebellum is necessary, because the neural system evolved as a new communication system out of the gastrular system.
