摘要
Insects have rather a small number of constituent neurons of the centralnervous system (CNS), especially of the brain, and eventually display rather simple patterned movements; a so-called instinctive behavior, which principally does not occur with memory and learning. The diversity of behaviors observed in insects have been shaped by millions of years of biological evolution. The behavioral strategies employed by insects must be efficient and adaptive to circumstances which change every moment. Controlling such behavior exclusively relies on the CNS of the insects. Insects will become an excellent model for understanding adaptive control in biological system. As an example of that, in the present study we demonstrate the strategies and the neural basis for controlling the odor-source searching behavior in insects.
