The collection contains about 200 permanent histological whole-mount preparations of all five postembryonic stages of locust nymphs and imago (from a lab culture of the insectarium at the Institute of Evolutionary Physiology and Biochemistry RAS), whose nervous system is stained supravitally with methylene blue. Some preparations are whole mounts of the central nervous system stained for the anterograde transport by cobalt chloride and nickel chloride. The staining by administration of cobalt chloride was additionally enhanced by silver impregnation. The collection also includes serial sections of the ganglia of the ventral nerve cords stained with hematoxylin-eosin. The collection was created by the author in 1991-2004 at the Laboratory of Invertebrate Neurophysiology (Head of the laboratory is academician V.L. Svidersky) of the Institute of Evolutionary Physiology and Biochemistry and was donated by the author to the Laboratory of Evolutionary Morphology (Zoological Institute RAS), where it is currently stored. The collection contains whole mounts of the dissected body of the animals, isolated ventral nerve cords, brain, cerci and wing buds. The preparations can be of assistance in learning about the structure of the central nervous system and elements of the peripheral nervous system: morphology and innervation of the proprioceptors, and the innervation of the musculature. The collection may serve as a study guide for the teaching courses on zoology and physiology and in particular for studying the evolution of the neural structures initiating the flight and controlling the walking, climbing and jumping in insects. The preparations may also serve as an illustration of the ontogenetic changes in the CNS and the peripheral nervous system.
