About The Cover

Reconstruction of the adult form of an identified abdominal motoneuron from the tobacco hornworm moth. The neuron performs different functions in the larva and the adult and, accordingly, shows a dramatic restructuring of its dendritic tree during metamorphosis. See page 477. [James W. Truman and Shirley E. Reiss, University of Washington, Seattle]
