They are the core components of both the central nervous system & peripheral nervous system.Neurons are sensors that send electric messages to the Central NervousSystem which send the electric messages back to the neurons tellingthem how to react, where the messages are finally sent back directly tothe brain. These messages travel at a usual pace of 100 meters persecond. 我学人工智能的课的时候老师讲过。。。速度很慢其实 100m/s
