CONSTANT TOPOLOGICAL ORGANIZATION OF THE COLEOPTERAN METAMORPHOSING NERVOUS-SYSTEM - ANALYSIS OF PERSISTENT ELEMENTS IN THE NERVOUS-SYSTEM OF TENEBRIO-MOLITOR

Evidence is provided that the topological organization of the larval neuropil is preserved during metamorphosis of Tenebrio molitor. Constancies in neuronal organization were due in part to persistence of individual neurons whose morphologies were individually followed. It appears that the phenomenologically static situation of the metamorphosing neuropil is achieved by stabilization and regulation due to cellular interactions. Comparisons are made with features of hemimetabolan postembryogenesis. Copyright © 1990 John Wiley & Sons, Inc.
