In which zone do cells get longer
WebWhat has been described here is the action potential, which is presented as a graph of voltage over time in Figure 12.5.7. It is the electrical signal that nervous tissue generates for communication. The change in the membrane voltage from -70 mV at rest to +30 mV at the end of depolarization is a 100-mV change. WebBy the end of the process of corticogenesis, the ventricular zone has become nothing more than a single layer of ependymal cells that marks the boundary of the cerebral ventricles. Not all neurons complete their migration successfully. In fact, the experts believe that only one-third do so.
