Action potentials (ap's), because they have a relatively small frequency of about 10 to 1000 per second are slow at transmitting information. Why is that? Suppose a ganglion cell ...

Subventricular zone
The subventricular zone (SVZ) is a paired brain structure situated throughout the lateral walls of the lateral ventricles. It is composed of four distinct layers of variable thickness and cell density, as well as cellular composition. Along with the dentate gyrus of the hippocampus, the SVZ is one of two places where neurogenesis has been found to occur in the adult mammalian brain.
