It is obvious to all of us - except you - that Hercules Rockefeller knows a great deal more about biology than you do. You just post reams of stuff you have looked up on the internet about your pet obsessions, without any idea what the material you post really means. And you are so stubborn that you refuse to acknowledge any error in your fanciful interpretations of this material, even when it is staring you in the face. Microtubules have bugger all to do with the transmission of signals along an axon. Their role is in cell maintenance and possibly in the way connections are made with other cells. The latter may be important in neural processes, since the interconnections between neurons are important. But they do not "conduct" nerve impulses along axons.
