Abstract
Direct visualization of individual axonal microtubules in Xenopus neurons indicates that they are primarily stationary, while another study shows that tubulin, the protein from which microtubules are made, can be transported in a non-microtubule form. Both results run contrary to a widely accepted model of slow axonal tubulin transport.
