摘要

It is known that a rat can take a shortcut even if it is an inexperienced path for the rat. Recently, the relation between the neurogenesis and learning mechanism has attracted attention. In this paper, we present a neural network model for the memory formation by introducing the neurogenesis in order to achieve successful navigation. We discuss two types of neurogeneses. Both types of neurogeneses play an important role in acquiring a universal rule in the navigation and avoiding incorrect learnings. It is considered that real animals use either type or both types of the neurogeneses presented here.
