Further evidence for the involvement of microtubules in the intra‐axonal movement of noradrenaline storage granules

Abstract
1. Constricted cat hypogastric nerve/inferior mesenteric ganglion preparations maintained in vitro for 48 hr have been used to study the effects of different concentrations of colchicine on axonal microtubules and on the proximo-distal movement of catecholamine containing dense-cored vesicles in non-myelinated axons.
